like airjor13 said , the diameter compared to the stock one is not much bigger, so you spend alot of money on sound basically
the bottleneck on the whole exhaust is the downpipe, if you want sound you could buy the magnaflow exhaust (the end of it) and replace the stock one and save some money. when u hear all the exhausts, did they all had stock downpipe?
not to jack the thread but does anyone have a clip of the 2j racing catback?
