Honda CRF300L/Rally MotoX Exhaust Noise Test 4K

Honda CRF300L/Rally MotoX Exhaust Noise Test 4K
Ask any enduro or older dual sport rider about the Honda CRF300L/Rally and they will tell you it's too heavy. They may have a point, even if you don't notice it as much when riding. One component which weighs a lot, in an inconvenient place on the bike is the exhaust system, and in particular the silencer/muffler/end can depending on where you are in the world!
In the UK, having a quiet exhaust on a trail bike is ideal, as the lanes are shared with other users, of which some groups are looking for opportunities to limit access for motorcycles. Loud pipes that scare livestock and intimidate other trail users are not great, and only strengthen the case for the trails to be shut.
Accordingly, whenever there is talk of exhaust replacement, one of the first questions is 'how loud is it'? The answers are entirely subjective and range from not too loud, to the ever helpful 'it sounds much better' (for what I always wonder!).
So, to this video, I have a MotoX exhaust from Thailand, and I want to know how loud it is, and more importantly, how load it is compared to the stock exhaust (see my other video)
The two tests I'm using are the ACU static rpm test and the 2 metre max test, and the technical descriptions of these can be found on:
www.acu.org.uk/Uploaded/1/Doc...
I'm also aware that there are sometimes claims that new exhausts increase power, and though this can be shown on a Dyno, I don't have one and don't plan to get my bike on one, so this is a noise test only. If anyone has a Dyno and is near the Peak District, please let me know, and I'd be happy to do a video comparing the power of the two exhausts.

14:28 Results
15:50 Explanation of the differences, comparable sounds and Conclusion
If you don't want to watch the video (and let's face it, it's not of interest to everyone!), the results are:
Test: Stock/MotoX standard/MotoX Baffle removed
Idle: 72.6dB/69.1dB/72.0dB
Static RPM: 83.4dB/80.1dB/81.3dB
2m Max: 96.2dB/97.7dB/99.0dB
Thanks to Suzette Shipman who suggested it would be useful to explain dB's (decibels) to people who might not be familiar. I'll not go into the detailed explanation as it's a long time since I had to know it and it's probably not that useful to understand the mathematics if you understand the scale. Essentially it's a logarithmic scale which means that for an increase of 10dB the sound level doubles and this scales up so taking 70dB as a starting point, as this is a useful baseline, roughly equivalent to a vacuum cleaner or traffic.
80dB is twice as loud as 70dB
90dB is four times as loud as 70dB
100dB is eight times as loud as 70dB
110dB is sixteen times as loud as 70dB
For additional context, exposure to sound levels over 85dB for sustained periods (8h+) can cause permanent hearing loss. Sound levels of 90dB+ can cause damage after 30 minutes and levels of
120dB+ damage after 30 seconds.
The upper limit set by the ACU does vary but is around 112dB for racing and 105dB for track days (though lower limits can apply) Max noise for an enduro bike is 112dB and for a trials bike 100dB.
I hope this has been interesting and useful, and if it has, please like and subscribe.
See you next time!

[@anthonylimpus7189]

Great follow-up vid Andre. You are becoming the "go-to" guy for anything Rally 👍 I think Moto X may experience a surge in sales - certainly I am now seriously considering this accessory based on your testing...

[@PeakMotorcycles]

For the alloy one at least. If the carbon end cap can’t survive 200 miles, then there’s a problem there… the alloy one is cheaper at least, and while it’s not as fancy as some exhausts, it is a bargain price!

[@chrisallen5548]

Surprising results, especially with the baffle out, seems a bit throatier - nice. Thanks for another top video.

[@PeakMotorcycles]

Someone described it as being a bit deeper vs the stock which is a bit chirpier. I guess throatier is similar to deeper!

[@2012theraven]

I removed the baffle in the tail pipe. noticed quite a bit more power. do you think the bike would be running too lean without a EjK tuner with it removed? i didnt do any air box mods, just the header and tail pipe.Thanks

[@Aengen]

Super content again! And anterestings finds. I have the full stainless system, and I think it is very much louder without the baffle. Really big difference! I actually ordered an extra baffle when I ordered it and have drilled out the all holes to 10mm in one of then, and maybe 8mm would have been perfect to my ears.

[@PeakMotorcycles]

There was another comment about how the type of sound can sound louder in that the stock exhaust has a more ‘chirpy’ sound and the MotoX has a deeper sound and perhaps we perceive a deeper sound to be louder? What I don’t have is the point between 4.5k rpm and 10.5k rpm where the MotoX becomes louder. If it’s 6k rpm then it would be more apparent, if 8.5k then less so.

[@joediesel8267]

Excellent video. Well constructed. You have made my mind up to purchase a MotoX. I like the sound level, here in Australia we have similar issues with noise complaints in some forests. The quieter the better I think

[@PeakMotorcycles]

Yup, there’s definitely two camps on this, people who want it loud, and those who would like to save a bit of weight as quietly as possible. Welcome to the 2nd camp, it’s busy in here 🤣

[@slakk5093]

Really good results! I will be going for this exhaust if I get a rally. Thanks

[@PeakMotorcycles]

It‘s the same engine, exhaust and mountings on the L as the Rally and this fits both.

[@jondotcom8706]

Another excellent, thorough video. Thanks for measuring the baffle dimensions. I think this will sound great with a screen-type spark arrester, but not too loud! I’m guessing that internal baffle is a good thing, creating enough back-pressure, and preventing it from being deafening. CHEERS!

[@PeakMotorcycles]

Yup, good luck with that. I hope it works out.

[@eurekaqi]

I have done just that and am pleased with the results.

[@240LTS]

... GREAT video so Thank you. Wrote all your numbers down and I am going to search for a sound test with the Yoshimura RS4 to compare. Installed the RS4 Full system on my Rally 3/2024. I have been a subscriber since I found your channel. Thanks again, Jeff

[@PeakMotorcycles]

Thanks Jeff. I’m sure it’s not perfect but then there’s so many variables based on environment and having calibrated mics etc. that said, doing multiple exhausts in the same way does give me a comparison. I have a saved eBay search for a RS4. If one ever comes up, I’ll do another comparison. Ride safe 👍

[@Terry-Tibbs]

Another excellent informative vid Many thanks

[@PeakMotorcycles]

You're very welcome. Apologies they are taking a while to come through...

[@cjohn8440]

Lots of data in this which I like. My goal would be to not increase the noise as well so this was great info. I was really trying to hold out for the Q4 but doesn’t look like FMF is coming out with anything soon so this may do for now. Thanks for another great video. 🤙

[@PeakMotorcycles]

As @Croaking Toad mentioned, I think the MotoX has a deeper sound and the stock more chirpy, and the deeper sounds louder, but isn’t, if that makes any sense at all! 🤣

[@keesverhagen9227]

And again, thank you. When is was asking for a soundfile without the baffle i meant just a few revving ups that would be recorded. But you can't really do anything without it being to be extremely pro.😂 But wel done.👍

[@PeakMotorcycles]

It’s the most popular video I’ve ever done with 1000 views in the first 12 hours, so clearly an inspired request. Thank you!

[@kiwiadventurer]

'André that was so thorough and just what I needed to know. You put a lot of work into that and done properly so.... much appreciated. Did you have the full exhaust or just the slip on silencer? Look forward to your next video. My Rally hasn't arrived yet, was due end of Mch but not long to the end of April now. Will be a great winter project for me here in NZ. My top 5 mods are Tyres, Suspension, Gearing, 550 ECU, Exhaust ...Cheers.

[@PeakMotorcycles]

Hi, the stock exhaust has a 1 piece link pipe and silencer, so unless you’re willing to cut that, just a silencer will be a challenge. This one is the full system. There do seem to be supply problems still for all sorts of things. I have a van coming which was ordered in May last year for a February delivery. That became March, then April, now May…. We shall see! From your list, I’d hold off on the gearing, at least initially; Honda have changed it from the 250 and made 1-5 lower and 6 higher. With the extra power and torque increase, 1 and 2 are quite low for off road use and 6 is great for highway cruising. Lucky you that you can get the 550 ECU. We can’t due to the EU/UK ECU… hoping your bike turns up soon. 🤞

[@yorkshiremanphil219]

Excellent video again André I have the stainless version as I thought that the carbon end cap might be a week spot especially when venturing off-road it will be interesting to see if you're bike rides better with or without the baffle in due to the loss of any back pressure Cheers Phil 👍

[@PeakMotorcycles]

Yup, will give it a go during the week and let you know. With the baffle in there was minimal difference from stock.

[@WillPower46]

Thank you for another great video.

[@PeakMotorcycles]

You are welcome. I hope it makes a bit of a change from just saying exhausts sound great/loud/quiet etc. I did look up rolling roads on eBay, just in case, but they don’t come cheap, and it’s a bit of an extravagance for a video 😉

[@Jmaninaz1]

Great job and very interesting! Even though I don't own a bike yet (the 300 Rally is probably what I'll get), this was a test I was looking forward to seeing. Good to see you can save some weight switching out the exhaust without it becoming obnoxiously loud. Well done and thank you!!

[@jasongeorge5228]

Hi, Great series on upgrading the crf300. It would be great if you could do a video breaking down the costs and shipping fees, what upgrades are a must have and costs buying direct from Thailand. Thanks and safe riding.

[@PeakMotorcycles]

Hi, Thanks. I did think about that, but the costs seem to vary significantly depending on weight, destination, size of package and import costs. This can be as much as 50%, and will probably be out of date before too long. About 20% (each) of the audience is in the US, UK, and Australia with 15% in Canada and Germany, and the other 10% a handful of other countries. I only have experience of shipping to the UK and even that seems to have varied depending on if there are import charges (or not!) I’ve found some things, particularly the Honda parts made in Thailand are a lot cheaper, but others (e.g. spark plugs) are cheaper if sourced locally. As for what’s a must, I think it comes down to how and where your’re riding, and how tall and heavy you are. If you’re 65kg, stock suspension is fine, if you’re 5’7” risers are probably not needed. If you only ride on road, most of the mods are overkill, and if you ride mostly off, then most would probably help. I’d rather folks make their own judgements about what’s a ‘must-have’ for them, and I wouldn’t presume to be able to define what other’s ‘must have’. To do so might even be considered rude! 🤣

[@anthonydendle4768]

Have been watching your videos for a while now well done , with this 1 and the baffle I wander if drilling the holes bigger or more holes same side would give you better back pressure for low down... Another thing I used to tinker with with smaller thumpsters etc was the weights of the flywheel to give better riding and economy as I learnt this years ago off people that rally the old ford escorts so would be interesting to see in the future if flywheels become mods to these as they look and sound like an awesome bike to own , I still cant source 1 here in Australia zero stock and no estimated arrival date like the ship sank bringing them here 😄😀😃

[@PeakMotorcycles]

Aye, the supply chain still seems to be broken. Even in the UK, ordering one now won’t be here before Easter… I guess I got lucky with mine (frame #99!). The flywheel is an interesting one. I’ve not seen it as a mod, but for a bike like this, where you don’t need the fast spin-up and all out power, a heavier flywheel would certainly help with the lower speed handling. Not sure about the holes. If I had a dyno I’d have a go, but trying to work out 1hp here or there or an increase in low down torque is challenging. Sometimes I think I can feel a difference, but other times I’m not sure.

[@RedC63AMG]

The sound “quality “ is better than stock especially with the baffle removed. I ordered this same setup yesterday along with the bash guard and frame protectors. Last thing I’m waiting on are the Motoz Tractionator RallZ tires !

[@PeakMotorcycles]

Yup, though one persons 'quality' is another persons 'torture'! I have a C43 with the AMG switchable exhaust, which no where near as exciting as the C63, is still a giggle with the pops and bangs. Some of my family members are less convinced 🤣. Sounds like you'll have a sweet setup. Have fun!

[@DaveDayve]

When u refer to quality, do u mean a deeper tone?

[@PeakMotorcycles]

@@DaveDayve me or Red? For me personally, I don’t think I’d use the word quality. Without the baffle, it’s a deeper sound, as you mentioned. That might be more appealing to others. I’m sure for some, near silence would be a better indication of quality, but everyone’s different. It’s also hard to capture on a microphone, so if you can find someone that’s done it, you’d be able to decide if it’s for you.

[@Aengen]

Oh, I have the Rallz on mine. Love them!!

[@steved733]

Thank you Andre for all the videos. They have helped me quite a bit with my 300 Rally. Have you noticed any negatives with the performance with the MotoX exhaust? I was hoping you'd do the acceleration tests for the new pipe, but I do understand why you didn't.

[@PeakMotorcycles]

Hi Steve, I haven’t noticed any performance impact. No flat spots in the rev range, and top speed is the same. I’ll ride it a bit without the baffle and see if that’s changed. A dyno is perhaps the only way to tell if there’s a real change, so maybe I’ll see if I can do that.

[@ronald8673]

Excellent video. Thanks

[@PeakMotorcycles]

Thanks Ron. I’m still learning, and plenty of room for improvement…

[@eurekaqi]

Thank you Andre. Absolutely spot on information for my exhaust decision. I too want to lose weight, improve exhaust tone and not produce offensive exhaust volume. You have shown that MotoX does all that. Also thank you for measuring the baffle. It does look like I can fit a US legal spark arrester. I am sure I can make it work but will only know if it requires modification when I get mine and try it.

[@PeakMotorcycles]

You’re very welcome, and yes, I had the same questions and I’m sure we’re not the only ones. Good luck with the spark arrestor and let me know how you get on.

[@mikeschlup5279]

I would drill some holes in the baffle...keep adding until the sound picks up a little bit..

[@twowheeledadventures5615]

MrScamp, Did you find a spark arrestor that will work with the Moto X. I just ordered my exhaust and I want to keep it legal as I ride USFS often. Thanks for any insight,

[@eurekaqi]

​@@twowheeledadventures5615 Yes, I was able to fit an FMF spark arrestor but since my new exhaust measured 42.5mm. internally and my spark arrester measured 42mm. some modification was necessary. The inside metal shows grind markings so tolerances likely vary unit to unit. I was able to remove a little material from both pieces to make it all fit. I also had to extend the mounting bolt hole slightly. I wish I could give a blanket recommendation but not everyone would want to do such fitting. I installed the standard FMF spark arrestor and find that it does nothing to quiet the exhaust. I plan to order their “quiet” Q4 version spark arrestor and give that a try.

[@tonydaulsportadventurer5186]

Hi Andre, great vid, I never would of thought your testing could prove that, I must ask though do you think that this will vary when you're riding as the rev range changes. I'm very interested to see what you think, cheers.

[@PeakMotorcycles]

It is a tricky one. Sound is such a difficult thing to assess, and I couldn’t think of any other way. This is how levels are measured for track days and ACU events, so if it’s good enough for them! The sound meter isn’t calibrated but it’s the same meter used for both stock and MotoX exhausts so if it’s off, it’ll be off for both. It will vary when riding, and ideally you’d do tests at every 1000 (or 500?) rpm to understand where it changes. Also drive by measurements are useful for the bike under load. I’d like to think that the 4500rpm is a sort of middle measure and most riding on a bike like this will be in the 3000-6000rpm rev range, so it’s a representative single value for comparison. Ultimately I guess the only way is to try it, and see what longer term effects are from noise fatigue and how many people complain 😉

[@Franzuccato]

Your videos are always extremely helpful. Well done mate! I'm wondering if it's ok to install the MotoX exhaust without an EJK/ fuel controller? Is that something you would recommend? I'm interested in buying it but I'm concerned about harming the engine if I don't buy an EJK. Thank you so much for your attention and well done for creating such great content. Cheers!

[@PeakMotorcycles]

I don’t have an EJK. I’ve done nearly 1000 miles on mine with no problems (other than a bit of the plastic on the end cap melted… get the one with the metal end cap!) I think you can probably squeeze some more power out with an EJK, though probably also need to do something with the air intake. It’s all a balance, exhaust let’s the air flow more freely out, EJK can increase the fuel going in but ideally this would be combined with more air too. I know that’s a massive over simplification! I’m not aware of any harm that can come to the engine without an EJK. Maybe it’s too soon to know for sure but there’s some folks with 3k miles plus on their bikes with the MotoX and I’m not aware of any problems. I was interested in the weight saving, not a power increase so haven’t tried an EJK yet. I’ll let you know if I do.

[@Franzuccato]

@@PeakMotorcycles thanks for your reply! I share the same thoughts and I'm not purchasing it to get more power.. I'm more interested in weight saving and a louder noise at higher speeds (so I can be slightly more noticed by other cars without having the whole neighborhood hating me for that 😅🤣). I'll give it a go with the metal end cap and will be looking forward for any updates you may have. Again, thanks for such quality content. 👏👏👏👏

@@Franzuccato you’re welcome and yes, I think it will do what you’re looking for!

[@davidroberts7490]

Another very useful video !👍 Certainly good to know you can buy a full exhaust system which is as quiet but lighter than stock and at a very good price.( Pity they don't sell the silencers seperately ) I bought another make for mine and am stll trying too modify it to get an acceptable tone. On the 250 Rally the stock silencer is so quiet that you start to hear whines etc from the engine so a little burble from an aftermarket tailpipe helps !😎

[@PeakMotorcycles]

On the 300, the silencer and link pipe (including Cat?) is one piece, so the only way to replace the silencer only would be to cut the stock one and hope! And yes, you can’t beat a bit of burble!

[@davidroberts7490]

@@PeakMotorcycles the after market silencer I got comes with a link pipe ( separate ) and the silecer actually has a beefy cat inside. Infact I was wondering if the Moto X silencer maybe has something else other than the db killer that you kindly measured for everyone, and the screened tube at the other end. At the end of the day these silencers are fairly basic, the good thing about the one you chose is that its quiet ,well built and a very good price.

[@PeakMotorcycles]

@@davidroberts7490 I’m not sure it does, as I think the header and link pipe were straight through. There is some wadding in the silencer, but little else. Then again, for £150 for the alloy one, which includes distribution and the retailers commission, they don’t have a lot to play with.

[@davidroberts7490]

@@PeakMotorcycles when you say the alloy one, do you mean the one they describe as stainless steel. If so then yes, its a really good price. I think with Thai Post delivery to Italy its 174 euro plus 64 euro delivery. I used Thai post the last purchase I got from them. Seems ok.

[@PeakMotorcycles]

@@davidroberts7490 yes. I thought the stainless referred to the header and link pipe, and that the silencer was aluminium alloy, but if it’s all stainless, then yes, that one!

[@aymericvn6346]

Hey man ! Awesome video, as always. I discovered you, and it's awesome to see someone taking care of the crf 300 like this, i'm learning a LOT. Quick question, i've seen that with the yoshimura exhaust, you need to reflash the ECU, becaus eit's running too lean, and at low rpm, the bike shut off. Anything like this with the motoX exhaust ? Is it good quality ? would be curious to buy it, since it has a good noise, without being annoying for others. Edit: any opinion on Akrapovic ? CHEERS !

[@PeakMotorcycles]

Hi Aymeric, welcome! So, there’s a a few things to consider. Are you in the UK or EU? If so, you’ll have a different ECU to the rest of the world, and currently there is no remap option that can unlock the Euro5 restrictions. If outside the UK/EU, remaps are available from the likes of 550 Performance. The problem occurs when there isn’t enough back pressure from the exhaust. If you have a straight through with no cat, then more air can come out than goes in and the bike will run lean. I ran my MotoX with both the end and mid inserts in and it was ok. Not quite the same as stock, but close enough. I think they are good enough quality for the price, but they are cheap. I’d go for the aluminium/stainless one if buying now as the end caps on the carbon ones melts! I’m not sure that Akrapovic do one yet for the 300. I’ve seen some that folks have fitted, but none that are CRF300 specific. If they have the same back pressure as stock, then they would be great. The quality is also good. I have an Akra pipe on both my CB1000R and my R1250GS. Both are dedicated parts from new and perform very well. I hope this helps. If I was buying now on a budget, I’d get the stainless MotoX. If my pockets were deeper, I’d get the Arrow with a cat as it’s homologated (same back pressure as stock), lighter than MotoX and has a similar sound to stock. Cheers,

[@aymericvn6346]

@@PeakMotorcycles i've looked into the arrow exhaust in france, and they don't sell the collector, because it's not "street legal". 670€ with the collector, i'm ok with that. But is there any problem if i only use the silencer + link pipe, without the arrow collector ? Thank you man, you're a gold mine, and really kind !

[@RickGreen_McNutt]

As a note, if purchasing the MotoX exhaust from BikerzBits in Thailand, it appears that package (the V1 full exhaust) has changed. They no longer include the db killer insert with the package, and they don't include a spark arrestor 'bucket' to go on the input side. I recently bought the V1 full exhaust and it arrived with a screen-type spark arrestor in the end, and no db killer. I had to order and ship the db killer separately. This seems a somewhat recent change. I'm going to assume that because I don't have the spark arrestor bucket (that goes on the input side of the muffler it seems) - because it didn't ship with one and I so far haven't found one - my exhaust is noticeably louder than the stock setup (with the db killer inserted). I bought the MotoX based on this test/review. I think it's important to note. The loudness is just barely tolerable for me (without the db killer insert, it was very loud and obnoxious and absolutely no tolerable to me), compared to the stock setup. I also note a slight difference in my db killer insert in that the leading surface (that's inserted into the muffler) is rounded, rather than square as seen in this video. My experience seems to differ from others I've talked with online - although, those I've talked with bought theirs well before I did.

[@PeakMotorcycles]

Thanks for the update. It has been a couple of years since I did that video. I did switch mine out for an Arrow homolgated exhaust with a catalytic convertor a few months later.

[@RickGreen_McNutt]

@baerv3753 Any updates would be appreciated. Oddly, I just searched the store ("Moto-x") and I get one exhaust system and the internal spark arrestor bucket in the search - last time I got the db killer - seems like the search isn't reliable or their products are 'shifting'.)

[@spartancaptain5691]

When you were talking about spark arrestor where the baffle was. In your first video you showed a small metal screen that went between the link pipe and exhaust and you stated that was a spark arrestor. Is that not correct? Why would you need another one?

[@PeakMotorcycles]

Good point! I’ve no idea 😁. We have way too much rain in the UK (most of the time) for a spark arrestor to be a thing. Baffles are more familiar, and if removable, they are the thing in the back end of the silencer. That seems to be the thing that is called the spark arrestor elsewhere. There were no instructions or other documentation with the guide, and if in the UK, the bit at the back is the baffle, (and why would you need another one!) then there must be a name for the forward one, so I, incorrectly as it turns out, called that a spark arrestor. I don’t suppose you know what the insert at the front end should be called by any chance? Happy to publish a correction if you or anyone else knows.

[@twowheelslater7112]

Just installed one. Header pipe is very well made but the can is just ok. Had to file the carbon to get the baffle out. Did you run this for a long time with the baffle in? It says not to on the package. That’s kind of stupid. Built with a baffle your not supposed to use. I like the sound with the end baffle in and the mid baffle removed.

[@PeakMotorcycles]

I did 250 miles across 5 days and the end cap started to melt. Not a lot and it didn’t affect the performance or fall off, but when I asked MotoX about it they referenced that note. I asked them if they thought 250 mile in 5 days was a lot (I don’t) and they stopped responding.

[@corax2012]

My theory as to why the Motox seems louder is frequency .... stock exhaust sounds a little chirpy ... the deeper tone makes the Motox feel louder.

[@PeakMotorcycles]

Yup. That makes a lot of sense. Chirpy vs deeper is a far better explanation than the over-used ‘better’! Thank you

[@DarcemanCRF300L]

I run this exhaust with a 550 performance tune... I run it without the baffle as well. I think there's something wrong with your decibel metre. I do like the sound in the performance gains and I'm willing to put up with it. But this exhaust is by far louder than the stock exhaust I have to wear earplugs and I don't rev it that high.

[@PeakMotorcycles]

Thanks! When you say ‘far louder’ have you measured it? Just curious really. Same for the performance gains, is that something you’ve dyno’d or it just feels more powerful?

[@DarcemanCRF300L]

No Dyno but it would barely spin the stock tires in dirt and now I can spin the tire if I want in the dirt while accelerating , it’s also far smoother on off throttle. Mid range is far stronger also. I will get a decimal meter and try it. This exhaust is very loud. I need earplugs.

[@DaveDayve]

I'm sure if u remove the inner spark arrestor shown as a small separate pipe, would definitely make a difference in sound level

[@PeakMotorcycles]

Yup. I expect that’d make it louder, as it’s then effectively a straight through pipe, though my aim was never to make it as loud as possible, if anything the opposite, while saving some weight.

[@DaveDayve]

@@PeakMotorcycles definitely agree

[@kevinim300]

considering the arena for testing is quite acoustically contained, i would say this is worst case of exposure over compared to more open areas.

[@PeakMotorcycles]

Never really thought about that. I guess being inside a garage or tunnel would be worse? Being on gravel, surround by rough gritstone dry stone walls is a pretty good noise absorber.

[@someguy5035]

Sound levels aside, have you noticed any increase in power or any other benefits? I am debating this or the full yosh RS4 setup. Any insights would be appreciated. Thanks.

[@PeakMotorcycles]

No significant power change. Some people swear there’s more mid-range torque, but I hadn’t really noticed much. Without a dyno, I think it’s how it feels rather than how it is. The full Yoshi will be better quality, better finish, louder and probably lighter. They look awesome and come at a price. If you don’t mind the sound and you have the cash, then go for it!

Correct

[@2012theraven]

Just installed one on my 300l. i couldn't get the muffler mounting bolt hole to line up on the bike with the spark arrestor installed. I had to take it out to mount it. did you have any trouble with that? the motox exhaust seems quite a bit louder than stock. I assume its because the arrestor is not installed. I did notice more low end power. great looking and sounding unit though.

[@PeakMotorcycles]

I had to twist the sections a bit to get it all to line up, but it went on as in the video and seemed to be an ok fit. I’ve found mine to be too loud so will be putting the spark arrestor back in. I’d not noticed any power change, but I maybe there’s something if it’s a bit more free flowing.

[@shmack-dab-in-da-middle3960]

Did you have to get the computer tuned after doing the exhaust and intake or air filter?

[@PeakMotorcycles]

I haven’t, but to get the most from it, yes I think a fuel controller and airbox mod/high flow filter would give the best results. I guess it’s what you want from it. For me, the bike has enough ‘go’ for an entry level dual sport. Saving 3kg high up on the bike was my main reason for changing the exhaust.

[@gary9768]

Can the OEM exhaust heat shield be fitted back on the bike?

[@PeakMotorcycles]

Not easily. If you could get some jubilee clips, with some threaded fittings that the stock heat shield could bolt to, then maybe, but it’d take some work.

[@jimconradtee1684]

How much did you buy your exhaust good sir? I have been trying to find it in ur description. Maybe I wasnt trying hard enought.😆

[@PeakMotorcycles]

I didn’t put it in, as the audience is no more than 20% in any country, and the shipping and tax costs mean that what it costs in one place is significantly different from another. I suggest you look it up on Bikerzbits and select your shipping country to get the total. Then depending on what your local import taxes might be, you may have to add that on. This is the exhaust: bikerzbits.com/honda-crf300l-rally-full-system-exhaust-muffler-231039.html So around £190 + UK shipping (£20) + £10 clearance charges + £40 VAT. Though it seems not everyone gets the import charges, so to the UK, somewhere between £210-£260. Other countries will be different.

[@FoxEnduro976]

I'm having a hard time removing my baffle. I have the screw removed but I can't seem to move the baffle. Any advice?

[@PeakMotorcycles]

Mine came out easy, but I had a stuck one on a Triumph Speed Triple 1050R in the past. Sometimes heat helps, so run the bike for a few minutes, then try again. Sometimes getting something to pull on is tricky. I’ve found that cutting a wire coat hanger and making a tight hook on one end that will hook onto something inside, perhaps through the holes in the end of the baffle, and then have a bigger bend on the other end so you have something to pull on can help. If none of that works, take off the silencer, the one at the ‘front’ end should be loose, and see if you can knock the baffle out from the inside with a broom handle or similar. Good luck.

[@tescofood]

Hi. Just wondering what indicators these are? Are they stock rally?

[@PeakMotorcycles]

Yes. They are LED signals and came as stock on my UK spec rally. They look like they are the same ones that came stock on my CB1000R so I guess Honda are making good use of them!

[@mosheasaf677]

I installed this exhaust and I am thinking of going back to the original exhaust. The reason, the replacement exhaust stinks of my shirts. The original exhaust with the catalytic converter does not do that. It's a real nuisance. Did you notice that?

[@PeakMotorcycles]

I’m sorry but I didn’t…. Did you have both inserts in yours? (The mid one and the end one) Could it be cleaning material, or something else melting onto it? I changed mine out for an Arrow with a catalytic converter, though not because of any shirt odours 🤣. Apologies and good luck.

[@deltajegga]

you should compare the yoshimura exhaust against this and the stock one.

[@PeakMotorcycles]

I would if I had one. As a Yorkshireman, spending £250 on an experiment was a challenge, which fortunately worked out. Not sure I’m ready to spend £800 to find out that it’s the same or worse, though if they want to lend me one to test, I’d be happy to! 🤣

[@EEEEMMMMKKKK]

Interesting. How does it compare to stock temperature and is there a heat shield?

[@PeakMotorcycles]

Hi, The stock exhaust has a large (plastic with insulation on the underside) heat shield, so the outside of that runs a lot cooler than the outside of the MotoX. I did a 200 mile ride with my Enduristan Blizzard panniers which included a mix of 60-70mph paved roads, town riding and trails to give it a good variety and I used an Enduristan Inferno heat shield. It worked well and though there was a bit of warmth on the bags, certainly nothing approaching a temperature of concern. It looks a bit like: instagram.com/p/CQfvlhSH0vl And this is their shop photos: enduristan.co.uk/collections/saddle-bags/products/inferno-heat-shield I've not properly tested it without a heat shield, but can take a thermometer next time I ride without luggage and see how it's doing.

@@PeakMotorcycles Thank you. i don't need measurement, only if it melts or not😃

[@materna5572]

Do I need to make any changes to the injection settings after the exhaust installation? Cheers.

[@PeakMotorcycles]

I’ve ridden mine with the stock settings, as have many others. In the UK, I’m not sure we have much choice as the UK/EU ECU is different to the rest of the world. I think the ideal is to do the exhaust, and an airbox mod to get more in and then adjust the fueling to match. I think this is possible on non-UK/EU bikes, but I’ve not had the opportunity to try it I’m afraid.

[@materna5572]

@@PeakMotorcycles I meant more about whether when changing to any accessory muffler, you need to make some injection adjustments so that the engine works properly, as the manufacturer recommends. I didn't mean regulation to increase power. When changing the original silencers to accessory, the operating temperature of the engine may change, due to different designs and exhaust gas discharge.

[@twowheeledadventures5615]

I find the stock exhaust to be really hot, especially for slow, off-road maneuvering. Do you find this exhaust system to lower the operating temperature? Thanks,

Hi, I hadn’t noticed much difference. The fan still starts up when it’s slow going. Perhaps it’s a bit more free breathing without the heat buildup around the Cat but I don’t think it’s a big change.

Hi, Not really. Top speed is about the same. No flat spots in the Rev range. Someone else had mentioned they thought it had more midrange torque at the expense of top end, but I hadn’t noticed that. 6th is still sluggish. If I can find an economically priced dyno, perhaps I’ll try that.

[@damacknificent151]

Does it run more lean? Runs hotter and fuel range difference?

[@PeakMotorcycles]

I hadn’t noticed much change. Some people have reported more torque and less top end, but I hadn’t really noticed that. I’ve been running mine with the baffle and spark arrestor in, and that seems to be a flow rate similar to stock, so I expect the ECU is able to monitor and manage the slight change.

Probably not. The only two E marked, street legal ones that I know of are the stock one, and the Arrow one (if a catalytic converter is used).

I used it for a few months with no problems and then switched to an Arrow exhaust. I don’t know what your local laws are though. I know that in Germany, modification is much more controlled than it is in the UK. Not sure about anywhere else.
