it was customlely made mate, it is full stainless steel, 3" with a hot dog cat and a 4" cannon, has that agressive rb sound when it opens up, its making 260kw very comfortable at the moment, not really fussed if i dont get rid of it and i was mostly after a 3.5" later on so i might aswell upgrqade it now b4 the turbos go ojn
cheers tony
