**First let me say, some of the pictures are courtesy of cafercr35 from sportbikes.net.**







1) First things first.

You need a muffler from a 06 and up R6r :dunce:



2) Prepping the new muffler

You need to cut 2 and 7/8 inches off. The part with the exup/butterfly flap is what needs to come off. Start measuring from the lip.



Dispose of the exup/butterfly flap piece.



Next I cut off the hanger on the muffler as well. To me it wasn't a huge problem with it not being the cleanest cut, because it is hidden, and the cut will not be visible.



3) Prepping the bike

Now is, what I thought to be, the hardest part. You need unbolt the support for the exhaust pipe. (blue circle on the right)



Next you need to literally pry down the pipe that is on the bike down from its original position about an inch or so. The goal here is to set the hanger that is on the manifold on the bottom of the hanger that is on the bike; wedging it if you will....





Now there's a few ways of performing the next task...



***It's important to understand that the whole manifold is still very secure even with the removal of this hanger***



You can fabricate something to secure the pipe from moving back to its original position, like this. This is really the better thing to do.





Or what I did is I used the original bolt I took off that supported the pipe and put a huge washer on it and fastened the bolt right back on, with the pipe under it. The purpose being that it will not bump over and slide into the original position (if it did slip over, it would cause the new pipe to hit the swing arm). This worked just fine for me!



4) Fitting the new, prepped, muffler on the bike

The outer diameter of the muffler is 2 inches. The inner diameter of the stock exhaust is 2. It does fit. What some people will do is apply a relief cut at the end of the pipe (the pipe that is on the bike itself) for extra clamping power. However, the clamp I used (pictured below) allows for more than enough clamping power.





Now bolt everything back up!



F.A.Q.


Q- Is there a lack of support for the mufflers weight? (If you went the washer route)

A- No, it would probably take at least 50 pounds to move the thing.

Q- Does it rub on the swing arm?

A- I had about a half inch clearance, with full travel of swing arm.

Q- Does your foot hit the can?

A- I wear size 11, and the back of my shoe made contact maybe twice while the time I owned the bike.

Q- Will the heat from the new muffler damage my plastic (because it is closer)?

A- No. There is a black metal shield at the base of the new muffler. This piece will be the only part that will make contact with your plastic. It acts like a heat shield, it will not get hot enough to cause damage.

I posted my experience over on the Exhaust forums.
http://www.r6-forum.com/forums/showthread.php?t=70657



It was easy. The lower pipe bracket needed to be moved because without it, the exhaust would go right into the swingarm and peg.
And i used the same clamp that held the old pipe on.

Just for updates!! Your mid pipe, i would cut a small slit on one side to allow more clamping power to hold it on.

THANK YOU!!! I wanted to do this really badly! How does it sound? I want something a bit louder than the stock exhaust. How much would someone sell one for?

I'm wondering about the non-stock exhausts also. I was wanting to find a used GYTR or something like it, but I don't want to spend the money and then have to resell the thing if it doesn't work.

Well, I think the gytr pipe is shorter, but fatter. Because it is fatter, I do not think it will have enough clearance without the swingarm hitting it. But do not know for sure. My two cents...

Where did you go to get the clamp? and is that all that is holding the mid-pipe and the exhaust can on? it just doesn't seem like a 2 inch pipe will fit into a 2 inch pipe without heating up the inlet on the can and stretching it a bit

The clamp can be bought at any autoparts store look in the exhaust section. I bought a nicer looking one . but who cares you can see it after its installed.
As for holding it on. it is fine. mine took a hard side swipe from a truck that jumped over and was fine. :mad: and what i did was cut a small slit in the midpipe to allow flexing so the pipe goes on easier and the clamp can bite harder. just dont cut to far or the pipe will not cover it.


And the 2 bros looks like it is thin like the r6r can. so it should be ok. just have to cut off some of the tubing like with the butterfly.
And you want to know if it sounds good well lets say lots of R6r are taking our headers and putting it on there bikes with there stock can and aftermarket cans, to do this exact thing but switched HAHA.

I can't wait to get this done on my bike. I picked up a stock pipe from a member on here, should be here middle of this week. I've been looking for a reason to take pics of the bike anyway.

I'm going to be doing a Graves CF shorty on my 2000. Using an aftermarket system is a lot easier because there's no exup valve ;)

nice writeup!

Damn, I didn't know the aftermarket pipes didn't have valves on them. I know what I'm putting on my list for Christmas.
