Yoshimura RS-3 vs M4 Exhaust Comparison w/ Sound Clips (Suzuki SV650)

In a recent video I made. I did a side by side comparison of the Yoshimura TRS & Yoshimura RS-3 slip on exhaust systems. In today's video we are going to be comparing my Yoshimura RS-3 to an M4 exhaust. Both of these systems were tested on second generation Suzuki SV650 motorcycles. If you are on the market for one of these exhaust systems, check this video out.

just ordered one of those polished M4 slip ons. Can't wait! Thank you so much for all your SV videos this whole channel is a treasure.

[@PASSIONBUILT]

Glad to hear! I’m sure you’re going to enjoy that sweet exhaust tone 😎 Thanks for the positive feedback on the channel!

After listening to 59 different exhaust clips, I think I'll go with the M4 slipon for my 2008 sv.

[@PASSIONBUILT]

Lol I commend you for listening to 59 different exhaust clips. If you have any interest in a full M4 system. I will have a complete M4 system for your 2008 available on my website WWW.MOTOPARTSSOURCE.COM sometime early next week. I also have 2 2008 SV650s. What color is yours?

@@PASSIONBUILT hmmmmm full system? I may just need that

[@sv650nyc7]

The big determinants are end pipe length and pipe diameter. The shorter and narrower, the louder and higher the pitch is. In my view the best sounding mufflers for the SV have a length of 13-14 in and a pipe diameter of 2-3 in. Deep rumble with a baffle, and loud but not annoying without one. Anything shorter (as is popular due to their low price) and it will be very loud. I had a Fuel Exhaust and now a Delkevic (both 14 in) and they both sound exactly the same as the ones in this video with their baffle out. Unlike the race mufflers in this video, they also came with baffles which make long rides much more comfortable on your ears. What few exhaust manufacturers tell you is how the muffler is packed inside. The cheap ones may just have a thin layer of fiberglass mat, that will need to be renewed after 8k miles or so. The better ones will have multiple layers of metal under the fiberglass packing to prolongue longevity. How airtight the packing is has a direct effect on back pressure and hence performance. But all after-market mufflers will have to be re-packed at some point, unlike the stock muffler that has steel chambers instead of packing material. Unfortunately that information is hard to come by. So I don't see the point of spending $600 on a muffler when a $200-300 one does the same job. However, stay away from the super cheap ones, as they may burn through quickly and will be torn apart if they're used in more aggressive riding scenarios.

They pretty much sound all sound similar, I went the Dominator exhaust plus the cans were much shorter. I have a comparison video like this with said exhaust. Good video though.

[@lightning1games]

Nice vid done well.

[@PASSIONBUILT]

Thank you!

[@Zokambaa]

m4 is way better in person... this video doesn't do either any justice

[@PASSIONBUILT]

The M4 does sound super nice and has an aggressive tone. 🙂👍🏼

[@JPRATT537]

M4 all the way

[@PASSIONBUILT]

M4 never disappoints! 🙂

[@ralphvalkenhoff2887]

Do you have the SV650R decal available? Really like it and want one on my side cover.

[@PASSIONBUILT]

Hey there. No, I do not have any decals available.

[@stanza77]

A bit new to this how come the SV650 with the M4 has fairings?

[@PASSIONBUILT]

Hey there. Both of these SV650S models came from factory with lower fairings. Unfortunately the one without lower fairings was dropped by the previous owner and he had removed the lower fairings because they were damaged prior to me buying the bike. The SV with the M4 is my other personal SV that came from factory with lower fairings as well. SV650s that come from factory with full fairings are considered SV650SF or SV650SFA if it has full fairings and ABS like the one in the video. I also made a video that gives you a comparison and detailed explanation of the differences on all 2003-2009 Suzuki SV650 second generation models. Linked below. You can definitely learn a lot about the SV650 from this channel so please subscribe if you enjoy the content 🙂👍🏼 kzbin.info/www/bejne/iIuXYqmGhr6kh7c

Fantastic thanks dude!@@PASSIONBUILT

[@PASSIONBUILT]

No problem at all. Thanks for watching 🙂

One more question, there is an 09 Gladius for sale near me for 3k. What upgrades does a Gladius/SFV650 have over the 1st and 2nd gen SV650? Can't find anything comprehensive online other than power and torque curve tweaks, thanks. @@PASSIONBUILT

[@PASSIONBUILT]

The SFV650 is a bike that was not really accepted by the SV community and does not appear to have much aftermarket support as the SV community does. I have honestly never had the opportunity to work with an SFV650 but as far as I know. A lot of the engine components are the same so I can assume that the cam swap upgrades and such would be the same or very similar.

[@tannerdaudelin8080]

Anyone know where to find the RS-3? It seems to be out of stock everywhere :(

[@PASSIONBUILT]

eBay is usually your best bet if you can’t find one online. I have them from time to time on www.motopartssource.com

[@renaissancerider4747]

Hello! How is the DB levels of the M4?

[@PASSIONBUILT]

Hey there. I don’t have a DB meter so I honestly couldn’t tell you.

[@Alpha-ms8nl]

my akra sound similar. But I would like to have some pops and bangs, could you help me? I already removed the db killer but do I also need to torn down the honey-cat within the pipe?

[@PASSIONBUILT]

Just remove your pipe if you really want loud pops and bangs but you will probably get sick of it over time and you can throw your pipe back on.

[@Alpha-ms8nl]

@@PASSIONBUILT nah in the country I live they give a €500 ticket and I have to give my bike to them

[@joatmon7621]

I have the yoshi rs3 and it’s super underwhelming. Literally can’t hear the engine over the sound of the wind even with baffle removed. Going to try out the m4 next.

[@PASSIONBUILT]

Wow. I love my RS3. But the M4 does sound very aggressive. Sooo to each his own. Hope the M4 works out for you.

Sad there's no trailblazer videos anymore

[@PASSIONBUILT]

I’m currently working on a back log of trailblazer content. I have been focusing on creating content for my business but you are right. I need to create some more trailblazer content. So stay tuned. I’ll have some uploaded soon! 🙂

[@t0xyg3n]

What are max dbs

[@PASSIONBUILT]

Hey there. I’m not sure. I do not have a dB meter. I apologize.

[@moonskyphotography2268]

Yoshimua sounds no different to my Beowulf

[@PASSIONBUILT]

I’ve never heard of Beowulf. I just checked and it looks like they’re UK based which explains why I’ve never heard of them. Some of the photos shown online of their exhausts looked like Yoshi pipes. I wonder if they get them from the same manufacturer and rebrand them as their own 🤷🏻‍♂️

[@moonskyphotography2268]
