Got a new 08' R6S. The super huge exhaust has got to go. Love the size of the R6 exhaust and it look like the end will fit, but it also gets loud as the R6 has some sort of fancy collector box to keep sound down. (At least thats what I can gather from reading some posts about the R6 to R6S exhaust swap)

Is there an option for a shorter style exhaust that isn't much louder than stock?

Thanks!

Find a used slip-on for the R6S and cut it down. Make a clean cut and don't disturb the packing and you can shorten the can a lot w/out it getting TOO loud. The first one I cut was a Blue Flame and I messed that one up so its too loud. The second one was a Jardine on my boy's bike and it turned out great.

damm i tought they stop making the R6S for the 08 models. well the only thing you can do to get rid of that huge pipe is to weld a gytr pipe or a stock R6 GP exhaust to yours. but its going to be loud because if am right R6S dont have cat. but it will look sick.

People in cars cannot hear you no matter what, and even if they could, they don't care. That whole "Loud Pipes Saves Lives" is actually pretty silly..

Shorter pipe doesnt have to be louder, The R6 is just as quiet as my bike with a very short exhaust. After market vendors usually don't want to make anything complicated with baffles, so they use the glasspack type mufflers because they are universal and are easier/cheaper for them to make.

I definately have a cat...

I'm sort of wondering if the R6S and R6 have such a similar engine, why hasn't anyone tried to fit the whole collector box and shorty exhaust from an R6? I'm guessing it doesnt fit for some reason or more people would have done it already... I'd love the have the short R6 exhaust and still remain stock for noise levels.

i hate to break it to you but im about 95% sure that your 08r6s doesnot have a cat....it has a muffler but please dont get those confused...i have an an 05 r6 pretty much the same bike minues a few things and definitely no cat.

o and 115hp not unless you have done some work to it...mine did 111 on the dyno with a full system, power commander, air filter and a custom map thats a decent up from the 104 stock

guys check out the Scorpion street extreme thread great looking exhaust but you have a removeable sound baffle to make it quieter no smaller exhaust will be as quiet as the stock one as they are huge and really restrictive they also hold a lot of heat.

I hate to break it to you, but my owners manual clearly states I have a cat :) Why would they put cats on the FZ6 and the R6 and not the R6S, that's just silly :) I'm assuming they all have to for emissions reasons at this point anyways... At least here in the United States anyways, other countries however, may not have cats on their bikes...

Everyone says the 03-04 R6's are the same as the new R6S, and while they are very similar they obviously have to update things to stay with the times, like emissions equipment and such... They certainly aren't the exact same bike... There have been updates and changes...

And yes, I do have 115hp, your thinking wheel hp which is about 10 lower. This is crank hp and it is stated as 115 right on the title.

For comparison for bikes sold in the US.... (These figures come right off the actual title for the bike)

07 FZ6 = 94hp
08 R6S = 115hp
08 R6 = 124hp

Now the R6 and the R6S also have ram air that adds about 5-6hp while moving at highway speeds and faster, but that is not taken into consideration for a stationary engine dyno. Those figures above are indeed what the motors make.

im not trying to argue with you im just tellling you there is not cat since i have torn apart atleast a dozen 03-05r6's and the 07"r6s" anyways heres a pic of the exhaust system setup directly from the parts catalog and if you dont believe go run to mrcycles and look up your year and model and it will show you that there is no cat.

i know for sure the new r6 06- current have a cat but the olders ones didnt i couldnt tell you why

o btw i know that those are crank numbers but most of us on here dont post crank numbers .....ask all the top racers what their crank hp and theyll give you a funny look.

as for adding 6-7 hp from riding down the street id have to see some kind of evidence to back that up

Dude I would just go look through the front of your bike and if you see a huge box right after your headers then you have a CAT if not then you probably don't..

there is a small catalyst in the first part of the big ass muffler (assuming #5 from that image) its basically right under the first riveted section.
how do i know this? well because i punched it out earlier today. so yes its there. want to see the pieces i took out?

Huh, yeah, in that pic I clearly see no cat... So i went out and took a good look at the bike, I certainly don't see any place where there could be a cat.. (my old 07' FZ6 definitely did have a cat, as I saw it when putting on new pipes)

My owners manual clearly states that this bike is equipped with a cat, what is up with that? Do they just lie in the owners manual like they lie about the fake redlines? Or is it possible there is some type of small cat in the bottom off the muffler?

I guess as far as performance goes im glad it doesn't have a cat, but i trying to figure out how they get it to pass emissions regulations without one?

Oh, and read this post complete with a dyno chart at the very end, it gives you some info on 5+ hp with ram air...
http://www.r6-forum.com/forums/showthread.php?t=9772

Ram air definitely works if designed right....

I don't have any wheel hp numbers for my bike so I posted the only number I do have. I'm certainly no racer :)

back to exhausts, how much shorter, If not that much, how about the street-legal akrapovic
Do you have any pics of that on a bike?

I guess ideally i'd love the super short R6 exhaust. but at the sounds levels that a stock R6 has... Are these engines similar enough that the R6's whole exhaust system would bolt right on? I got to imagine that there's folks selling their R6 exhaust when they upgrade?

you can put on the last section of the R6. the header wont work, you can make the "slip on" piece work with a little persuasion.
Right, I have seen that I think in the how-to section. But when I do that i also get no muffler and a very loud exhaust.. :)

cutting down any exhaust is going to make it louder
Well, I guess that's where I was going with this post. The R6 is not loud and it has a short exhaust, so it certainly can be done. There's got to be a way to replicate that on the R6S....
