i am running stage 2a at the moment and was wondering how important is to have a 3" exhaust as i think mine is just under 2.5"
i still have the standard elbow on at the moment also.
is it worth putting a aftermarket elbow and 3" exhaust on it,
just thinking of changing for a blitz nur spec and wanted to see if i should change the elbow at the same time
any thoughts would be good
