I'm considering a switch from an M4 full system to Yosh. Will I need to re-jet the bike? It's a '00 GSXR 600.
Shouldn't have to but a dyno run before and after will tell you if there is a difference in the power curve and maybe some jetting will help bring it back if it was lower. Why are you considering the change? M4 makes a hella of a pipe.
Right now its got an M4 header with M4 slip-on. I'm guessing the f/s can was damaged. I found a brand new Yosh RS3 full system w/ Ti can for $200.00. It's not that great a deal though, if I have to spend $250 to dyno tune the bike again.
