i have an 06 vfr800 and i just put a two bro's exhaust on it.. the one on the right side works and the one on the left is not hooked up. If I was to make it a true dual exhaust again by modding a pipe to the left one and possible taking the cat converter off will i be ok by doing that? will i lose or gain anything by making it a true dual again?:usa2:
