Cutting down a Yoshimura muffler?

I have an RF900R Suzuki, and the Yoshi can is badly dented near the back end. I figure I could drill out the rivets, cut off the last 6" or so off the can and baffle, and re-attach the end plate.

Anybody try this on a sport bike? If so (and only if you have actual knowledge -- no guesses from squids, OK?), did it become obnoxiously loud? Were there other problems (with performance)? I'm not worried about mounting.

Lastly, is there a shorter 3-hole muffler that would work (in case I screw it all up)? URL, if you have it. Thanks.

Added:
1) I do have a stock muffler, but it's so ridiculously heavy, and it is huge -- bad for back-seater's leg to clear.

2) Bike is set up for Yoshi (full-length) as it is.

don't do it your bike will not run very good,be annoyingly loud and mess your tuning up. the yoshimura mufflers are designed to a certain length so they perform. you will be better off replacing it. my younger brother has a rf900r and we just replaced the yoshi pipe with a termigoni and now we have the tunning right it goes and sounds great.

it'll totally mess up your jetting. and you do not mention which yosh can you have. possible the internal baffle will not take it.

assuming you have the skills to cut down the can and the baffle, yes, it WILL be very loud.


If it were MY bike? I'd buy a new slip-on.
