ba xr8 exhaust help!
i just bought a difilippo big boy system from the cats back from ebay for $1350, i recieved it yesterday and bolted it on but its not what i expected.
i didnt get the note that i was looking for and its no where near loud enough. i was wondering if i buy some headers and a hi flow cat will it change the note and make it louder? ive also been told that i would be better off with a dual 2 1/2in exhaust because my xr8 is fully stock and this exhaust is too big?
would like to hear your opinions or solutions please
