Question has anyone done 3" from cat back in their passat preferably turbo and straight through pipe want to know what sounds like.
I have a 3" S/S system from the cat back, but not a straight through pipe, it has two APR mufflers fitted, I have a 103 kw turbo diesel motor with an APR cold air intake and a performance tune. Sounds a little throatier, but not much else.
