I have just changed the rear diffuser to an S4 diffuser and want to fit twin 3.5" outlet single skin staggered tailpipes, local custom exhaust place only has 3" and in my opinion they look a bit small for the diffuser, they have 3.5" double skin tips but not keen on the look of them.
the pic is ideally what I am after as don't really want a high polished chrome look either!
