SlipOn Vs Full System

[Ryan300exRider]

I have a Yoshimura slip on and i just ordered my headpipe to complete the whole system....I was wondering do you notice the power and speed gain with the full system and jets over just the slip on ?:huh

well i know with the 400 u gain soem top end but sacrifice some bottom unless you have motorwork, it should make a improvement on your 3
