2021 Moto Guzzi V7 850: Mistral Exhaust Sound Comparison

[@VicoLanza]

Compliments on the review, exhaustive and precise! As an owner of the same bike and exhausts, I can tell that the sound it's very close to the real feel on person!

[@dreamreaver23]

Thank you very much, I tried really hard to get it as the best representation as I could. So your comment is greatly appreciated. Ride happy!

[@Dreddingbath]

‘Exhaustive’ 👍

[@Deetroiter]

I rode around for a while with mistrals on my 750 and no DB killers in…now I understand why no cars wanted to drive behind me LOL…115 db omg The sound was really damn good, but I out the killers back in. I have a tune on mine but still seems to run a little stronger all the way around with the killers in. Great video, thank you for sharing it with us!

[@electricsynthesis]

You do NOT need an ECU remap when you remove the DB Killer, I have asked Mistral about this directly and mentioned so

[@FrankB1110]

Sounds awesome, would keep the db killers in personally cause I'm not 16 anymore

[@dreamreaver23]

lol, yup, that and I ain't trying to compete with "Harley Guy" lol

[@jeffgravitt3732]

Or Squid Guy.....because you haven't that DNA. ;-)

[@mark.e.p]

I had a T3 in the 80's and put Lafranconis on, what a beautiful sound.

[@Varagis]

Very well detailed review. Thanks fot that. Here, in Italy and Europe as well, we have a lot of restrictions for what concerns pollution and the result is bikes that make the same sound of a toaster. I'm not a fun of excessive noise, it gets rude...but...there's no Guzzi engine without Guzzi music! Ciao

[@dreamreaver23]

hey, glad you like it.

[@jsirkerp]

I am more of the quiet type. But man 10 pounds weight savings is great. I would levar the DBK in because of the noise. Great video.

[@lorimcquinn3966]

Your bike sounds great w/ the Mistrals. While I don't think you'll get any complaints from the authorities or neighbors, I did notice the disclaimer on the supplier's site for use of the bike with the Mistrals, this is usually reserved for parts which don't comply w/ U.S. emissions requirements. 10 lbs loss is really impressive, it's very tough to cut that amount of weight, makes the price easier to swallow:-) Find some tight twisty back roads and enjoy the new sound.

[@markfortin8286]

It sounds great with the baffles in. You can even hear it's out of tune with them out. The improved sound is pleasing, and knocking 10+ pounds off the bike in one go is a big benefit, too.

[@dreamreaver23]

agreed, and yes the 10 pounds off the bike is awesome, according to the dyno stats there is roughly a 2 hp increase and a 1.5 ft lbs torque increase. all of which are very welcome. lol

[@shabletent]

Thanks for that very interesting comparison, I now know what to get when I get a V7 850.

[@dreamreaver23]

Awesome, glad it helped

[@emixmim]

Excellent video! Thanks a lot, sealed the deal for me!

[@dreamreaver23]

Thank you, so glad it helped.

[@bikerbeliever8169]

It's at almost perfect volume level with the db killers in.

[@dreamreaver23]

I really like it with the DBK in, gives it a little rasp and just a bit more volume. I won't be taking them out for anything other than this test.

[@endo9913]

The best review out there on this subject. Many thanks! The screen look good on your v7. Does it work well and if so, which one is it?

[@aaron.hudacky]

Great video and attention to detail! If I get an 850 V7, I'll be watching this again, and I subscribed because of this video. I have an 18 V7III Special with long Mistrals. The motorcycle has 18,000 miles, the Mistrals 16,000. Mapping isn't required on mine with the DB killers out, but I also have an unusual (in the US) E3 compliant version with cats that I got from Germany because they were cheaper. No remapping was required, although I did try an aftermarket map briefly. The sound is deep, and I measured decibels but don't remember the numbers... maybe I'll make a video about them. After two years, they look like new and sound great. I'm sure yours will be the same.

[@dreamreaver23]

Great info and thank you for the info

[@stevemiller1203]

I like this comparison, big weight difference, the gap doesn't bother me at all, in fact I think it looks fine, I actually prefer the sound with the db killers in so that's perfect, no extra money to have to spend on a remap. Thanks for the video.

[@dreamreaver23]

Yeah , I do like the DB killer in sound. Even in the video it's hard to compare just how loud the exhaust is with the dbk out. Wife was sitting about 20 ft away, and said that it hurt her ears.

[@grahamblair5566]

Very helpful review -real world, context, in the UK, got it.

[@dreamreaver23]

thanks bud

[@thegnosianjournals1350]

Great review. I like the sound both with the db killers in and out but will have to try it out myself to see which I would keep. I like the fact that keeping them in I don’t have to anymore though. Thanks!

[@dreamreaver23]

i would also say that with the sound in, you're not obvioius to police for being too loud, it's just a bit more bite, but not obnoxious. works really well.

[@yuriymolchanov8711]

Thanks a lot for your test! Brgds, Yuriy

[@Mandofour]

Thanks for doing this awesome sound test. Actually, the stock don't sound too bad compared to other videos out there. I would love the Mistrals but not want to risk it being illegal and also affecting the insurance.

[@dreamreaver23]

That's understandable

[@weed46]

This is how you do exhaust videos

[@dreamreaver23]

Thank you, Glad you found it helpful.

[@NormanGnome11]

Am sure I read somewhere that a 'get around' for the remap was as simple as disconnecting the battery for a few minutes and then connecting it back up with the new exhausts on - the ECU will then 're learn' the parameters for correct fuelling.

[@pacmancalgary]

Great video. The DB killers out sounds fantastic. I've got a 2014 V7 with Agostini slip ons. With the DB Killer's out it's unbearable, obnoxious and embarrassing. DB Killers in still sounds louder than yours with the DB's out. I prefer your sound

[@hschokker86]

Satin, polished or black on my v7 ii stone in black? Black is t really an option since the rest of the exhaust isn’t black probably polished looks best(?)

[@dreamreaver23]

Polished looks nice, but I wouldn't rule out black, sport bikes do that all the time. Maybe just some photoshop to give an idea on how it will look

[@IIshadowriderII]

Very nice video dude! Mistral or Arrow ?!!

[@reborn3559]

If I heard well, you say that the cat is out on these mufflers, however I just ordered a pair, and it is written clearly that they have a catalyst Euro 5. Great video though with proper recording, thanks. Gerard (Paris France)

[@LuisRamos-nz8us]

Hi! Congratulations for the video! I wonder to ear the sound of the longer version exausts ! Is the sound the same as the short version or there are diferences?

[@dreamreaver23]

that i would like to know as well.

[@hugodacosta]

In terms of sound and weight loss, that exhaust is a great improvement. But that gap...for someone with OCD it can be annoying.

[@dreamreaver23]

Trust me, I understand completely

[@mark.e.p]

Get some clamps on.

[@bozzy9887]

Do Agostini make clip ons yet for your bike? What made you go for Mistrals? Sounds good with DB Killers in.

[@dreamreaver23]

as far as i know, Mistrals are the only ones on the market for the 2021 v7 850 as of right now. I looked at a lot of the previous year models and the different exhausts on those, and the mistrals were always one of the better sounding ones. That and price and availability played a factor. lol

[@alextoma6992]

Any thoughts after almost a year with the Mistrals? I plan on using with the DBkillers in and I was thinking if the engine runs well and whether they get annoyingly loud on longer rides.

[@dreamreaver23]

after a full year with the mistrals, i have no complaints, and am enjoying them even more as the bike really set's in. the sound is nice, and audible in the lower speeds, once you get up to highway speeds of around 70-75 mph, they are still audible but not very loud, and definitely not overbearing. the wind is much louder than them, i still would like to try with the db killers out, i just don't want to flash and remap in order to test it.

[@FirinMahLazer1]

On film I think they sound better with the dB killers out but I'm sure it doesn't do it justice to just how loud it actually is.

[@Speedytrip]

Great exhaust video thanks!

[@dreamreaver23]

Glad you liked it!

[@whitmanft]

i dont mean to get off base here but how does it ride w/ a passenger(for the driver and passenger) thx

[@dreamreaver23]

i will try to convince my wife to go for a ride as a passenger with me. it's hard, because she has her own motorcycle and would rather ride it that ride as a passenger. but i will see what i can do about that.

[@coreyk644]

Very nice. Are bd killers removed from the back end or from where it attaches to header. Thanks

[@dreamreaver23]

The back end

[@Roger_Ramjet]

Nice vid. Are the pipes plug and play or do they require tuning ?

[@dreamreaver23]

Thank you, so these ones are specifically made for the 2021 V7 850. If you don't take the decibel killers out no ECU remapping or tuning is required, however, if you take out the decibel killers then you do need to have a remap for the ECU.

[@Roger_Ramjet]

@@dreamreaver23 got it. Thanks a lot. It sounds perfect with them in. I am to the Guzzi fold with a 1981 V1000 G5 but I'm loving your bike too.

[@dreamreaver23]

Very nice, and thank you for the compliment.

[@sirrealistoftheparanoiacsh9182]

Just got mine installed a few days ago with the new ECU map and it is glorious! What are you going to do with your stock exhaust? Sell them?

[@dreamreaver23]

Not sure if I will sell them or keep them. Did you keep the db killers in, or take them out?

[@sirrealistoftheparanoiacsh9182]

@@dreamreaver23 I kept them in. Taking them out makes the engine run especially lean. My mechanic was telling me he had a couple V7s come in for an exhaust swap and they wanted the DBs out and they were back within a month with issues of rough idling, stalling, etc. I would say if you are going to take them out, just upgrade the headers to mistrals as well and buy the ECU reflash from GuzziTech and just remap the entire system with a custom tune to suit the new hardware.

[@Lemmy12345678]

@@sirrealistoftheparanoiacsh9182 Hi there! What new ecu map do you mean in your first comment? Some new map which can be installed at the dealership without a big hassle or do you mean a complete new map directly fitting your motorcycle with reflash and all? Which would be pretty expensive to be honest... I also wanna install the Mistrals a few months from now and definitely keep the dB killers in. But I would like the bike to run perfect with these new exhaust but without spending hundreds of dollars for the reflash tool alone...

Hi mate and thanks for the video. Quick question, how do you take the db killers out?

There is a little screw in there with a weird t bit. It has a hole in the center. Just unscrew the screw and pull out the baffle

Anytime buddy. Next I'm probably gonna look at the flyscreen, to test out, and then I want to look at saddle bags.

[@reborn3559]

"N.B. For the installation of the exhausts, in case of possession of the Special Edition version, it is necessary to purchase the relative specific brackets " I read this on the Italian website. Could this be why you have a gap between the mufflers and head pipes ? (A wild guess, since you probably had not missed this)

[@fredarthur-art]

thanks but do you need a special pair of exhausts for the or just order an additional part to mount?

[@reborn3559]

@@fredarthur-art Sorry I don't Know. I have since bought a pair for my V7 Stone, I have the gap too 😜. Not a big deal really

[@fredarthur-art]

I talked to mistral support. They told me for the "850 special" (NOT "Special Edition") you do not need an extra bracket and that the exhaust can be fitted without a gap - you just need to push it a little further in. (Funny thing they have the gaps visible on their own photos on their product page.)

[@reborn3559]

@@fredarthur-art If they say so. I don't think it goes further in, plus you need the tightening brackets to be in the right place

[@fredarthur-art]

I will find out soon. Here's the answer I got from them "it is solvable :) It is just a mounting mistake. When you are pushing the exhausts inside, you will feel like a step and think you cannot push it inside anymore, instead, there is almost one cm more so you will just have to gently push inside a little more"

[@Dreddingbath]

Thanks dreamweaver, I’m persuaded, they’re a must have. Does this really remove the cat, I don’t understand how they can meet the same Euro5 standard as the stock pipes with a cat, but I’m not arguing. Thanks for the great video.

[@dreamreaver23]

Anytime, yes they do remove the cat.

[@alextoma6992]

I asked Mistral and they said they still have the cat

[@mrsilbo6499]

Easiest way to lose weight & enjoy a lovely exhaust note! DBK in is definitely the way to go.

[@frufan100]

Gosh that sounds good

[@saddle8bag]

How does one get the ECU modified? Does a dealer need a dyno? Can they do it directly or does it need something like a Power Commander? Also, are the cats in the mufflers of the OEM exhausts? Usually, mfgs put them in the header pipes.

[@dreamreaver23]

hey buddy, there are tools that you can buy online that allow you to do the ECU Remapping, but to get an ecu map, you need to pay money to different people who have them available. the most used for moto guzzi is Beetle Maps, you can find some maps and info on how to do it on Griso.org. as for the location of the CAT, at 1:44 they are on the left side of the screen, on this moto guzzi, they are after the header pipe and before the silencer, i guess technically the cat and silencer are one piece.. so any change to the exhaust removes the CAT.

Is it the same engine like in breva 850?

[@jfro5867]

Appreciate the video. I actually think the original silencers are best. They look ‘right’ and I think the quieter more refined sound sounds the bike better (think Rolls Royce with a noisy exhaust, just not right).

It sucks that you have to pay an extra 800 on a 900p euro bike just to get a decent sound.

Dont waste your money on a exhaust for this bike,I got these mistrals and the bike started running badly after a ecu remap (upmap) and original exhaust on it ran beautifully put on mistrals and it was better than before the ecu remap but still not good,hesitant to rev less crisp throttle response and worse of all they create a vibration in the bike so for me it's the original exhaust all day... Almost forgot after remap the original exhaust definitely have a slightly deeper sound to them.

Thanks for the info

[@styx85]

Sounds like the remap was the problem, not the exhaust? You don't need a remap if you leave the dB killers in.

Please guys don't use your kill switch to turn your bike of, it's best practice to always use the key to shut down the engine because this turns off the electrical system as well. The kill switch is an emergency use only.
