Well, i really wasnt expecting much anyways, im thinking i'll start from the top and work my way down for the exhaust. Extractors, CAT, then cat back.
Hmm, should be seeing some gains, coz i knw for a fact im loosing power / compression with the massive 3 or 4" i got on the NA right now. Waiting for my group certificate and lovely tax return hehe!
