View Full Version : S4 Muffler into a A4?

I have a full b5 s4 exhaust laying around was wondering if i can swap my b5 1.8t muffler with the s4 muffler? Any differences? Or just a simple cut and weld?

Everything should be the same, only thing that may be different is the inlet size, maybe have to reduce the opening on the muffler, not to sure about the s4 stock size piping compared to ours.

Yeah... I blew a tire on my old set and it needed new tires neway. So I just decided it would be a good time to get a whole new set of wheels and change it up a bit ha. The black/black was getting a little old with me, wanted a different look.
