I have a 2003 gsxr 600 with stock exhaust and headers on my stunt bike. If i got a FULL tri yoshi exhaust, would i have to rejet or adjust/add anything to my bike to be complete?

 

Why would anyone want to pute a Yoshi exaust on a GSXR ? I mean, That's just un-heard of.

 

no doubt! you want a Muzzy on that pig!



leave it stock, aftermarket exhausts are aimed to give you more HP/Torque in the upper RPM range, typically 6000-9000 depending on the bike. Those systems usually rob the bike of low end torque which most of us like for stunting. even on a stock bike for street wheelies... leave it stock, you dont need any more power to make wheelies. If you absolutely must attract attention from the cops, get yourself a used D&D slip-on off ebay. Nah, you really dont need to mess with the EFI, you can if you have a power commander but you wont notice the power difference unless you have a dyno to read and tune it or unless you are on a track and then you can tell if your lap times are 1/100th of a second faster. Even if you had a power commander, you still can not unleash the full potential of the bike unless you have hours of time and access to a dyno to keep playing with the maps. Powder Commanders are a waste of money in that respect.

 

Gotcha.....thanks. I will just leave it the hell alone then and worry about stunts instead of sound. ha ha
