Did it on my '97. Perfect fit first time, sounds great with an obvious power-boost as soon as I left the driveway. Did'nt even do any carb jet mods or anything from stock and have had no problems at all. Nice.

 

I'll be in the market for exhaust here soon........guess I didnt realize that the two bros and procircuit were louder.....how much louder????

 

The Pro Circuit that I have is somewhat louder but not so much you neighbours will lynch ya. Sounds really good.

 

There's always the option of a stock 01-02 GSXR 1000 muffler. A bit louder than stock, but not obnoxious. I have one for my DR650. See here for info.

 

I contacted Two Bros on Friday. They won't make me a carbon fiber slip-on. They said it'd get too hot
I still like the Pro-Circuit... I wonder if it's quieter than my Yoshi?

 

I had Pro-Circuit ones and really liked it. It is much louder then stock but I've never had a problem with cops. It was so nice that some scumbag stole it of my bike and now I'm using stock one.
