Hi there just purchased my new 2022 R7,
Looking for advice on best exhaust system for it,
can anyone help please.
Thanks Darren
This forum is full with best exhaust advice. But as it is in real life also, what means best and what is your individual preference.
In my opinion, the best of all is, that there is already an exhaust mounted. I will go with it.

In other words, it depends what you want. Some just care about sound, some a power increase, maybe both. There are unfortunately not a lot of A) Reliable dyno tests to show power differences side by side from the choices available. B) noise sample videos/charts.

I have the Yosh R77. Their dyno chart shows very similar power gains to the Graves, the only other dyno chart I've seen, but they could both be marketing nonsense. People here have done dyno runs but there was no stock run done so who knows if Yamahas advertised numbers are accurate.

As for the sound, I really liked the Yosh but it eventually became tiring for my old ears in the rpm zones I'm typically riding in so I installed the DB Killer. Much better for my taste.

Hi there thanks I’ve been looking at the yodh more and more now. It does sound nice on the videos, just hope it’s sound good in real life. I’m heading to the Scottish bike show next week so hopefully I can pick one up

I’m running the Yosh R77 with the DB Killer and she sounds AMAZING. I get compliments all the time on the look and sound. I went with the DB Killer right off the bat because I didn’t want to be too obnoxious for my neighbors when i leave for work at 530 am lol even my husband, who rides a new S1000RR, absolutely loves the sound of my Yosh. Getting a good quality sound clip is impossible - I’ve tried - but I can honestly say my first sound check after I installed it… I drooled.

Did you go with a full system or slip on?

Having run it both ways, I do prefer it with the DBK insert in. I wear ear plugs and it was still obnoxious without it.

Super glad I went with the killer right away then. Just did ~8 hours on it in the last 2 days & couldn’t imagine it without the insert in. It’s just loud enough at cruising speed (for us, between 60-90 depending) that I can hear it over the music on my Cardo but it doesn’t drown it out or irritate me. I watched enough YouTube vids of folks saying it was just painfully loud without the insert in so I didn’t even wanna try lol

Full system
Did you change the air filter? ECU flash or Dyno tune?
The bike will make slightly more HP with the decibel insert in. Thats what I was told when I put the full exhaust on my ninja 400. I went with an aftermarket air filter with the full exhaust and had the bike Dyno tuned.

Nah I didn’t do any of that. I changed the exhaust just for appearance & sound - I’m not HP chasing or anything. I’m not tracking it & everyone I ride with rides a leader bike - I ain’t racin nobody haha

I had to read that a couple times, I thought you were saying with the insert in it's just right for someone who is 60-90 years old. LOL Regardless of the exhaust, I nearly always wear ear plugs, the highway noise at those speeds (wind noise, not age) can be just as dangerous as the exhaust sound. The only time I am not wearing them is if I can't find a pair. They make the sound from the Cardo a whole lot better as well. Not super sound deadening ones, just deadening enough to take the edge off. Like these, from the Wal Mart shooting gear section.

haha my apologies - I definitely could’ve worded that better lol we have a ton of those plugs around the house (we shoot a bunch) so maybe I’ll give them a try next time we go out for a long ride. I hate earplugs in general - years of flying in a helicopter with plugs in every flight did that for me lol but I’ll see how it goes for wind noise. I don’t get too bothered by it, if anything I get more annoyed by the neck pain fighting the wind lol. Once I reach that point I’ll just tuck in for a bit to get some relief

I went with the Akrapovic from the MT07 for the clearance on the lean angles. There are two models. The first one has more flow but, the second one has a better cat if that is what you want. View attachment 980
I didn’t even think of the clearance of the Yosh until someone here posted the photo of the contact point on it. Gonna be real pissed if I start scraping mine up haha

It was my damn son that did that, and you need to be over really far to hit it, I just wanted to point out it is quite possible, that it is the hard part location that hits first, apparently. I do not have stock pegs but what I am using are in the stock mounts. I would think the stock pegs would have made contact first, certainly if they had the peg feelers still installed. There would have been no contact this time without the R&G pipe protector, but I am glad to know that point was safely reached.

A study from way back showed that wind noise was far worse for your hearing than bike noise, I guess that is very much bike dependent though, and helmet dependent now too. For me, it is just much more comfortable wearing ear plugs and it greatly improves the headset sound. Knocks the high end sounds down and increases the bass to a much more good stereo like levels. Phone calls sound better too.
