I have Silmotor exhaust, they sell slip-on and whole exhaust.
Tried Akrapovic, but is was too noisy for race use, even with noisekiller.

and yes you need to re-jet, it would be too lean.

I'm getting a FMF Powercore, I rode my friends bike who had that on there. Lets just say it felt like 10 hp difference. Its alot lighter than stock too.
