I purchased my CBR a few weeks ago, it has a Yoshimura RS-1 Stainless pipe on it, well the pipe is stainless and the canister i think is titanium. DOes anyone have any opinions on this exhaust, is it good or should I look into upgrading?

I would save your money and keep what you have. Yosh is a good pipe ans I doubt you would notice a performance increase with a different one. The only reason I would change up is if you don't like how it looks.

THanks for the insight guys, I think its a good lookin pipe so I guess I'll keep it. Its still like new.

Another question, wuts the difference between the RS-1 and RS-3?

isnt rs3 side mount exhausts. thats what i had on my gixxer. and rs5 is the undertail one for honda right? correct me if im wrong guys.
