I was just thinking to myself I wonder how a single muffler exhaust system would perform on an S4? If you had the same inch aftermarket exhaust system built by the same company but instead of having the dual mufflers you had the piping connect into one muffler would it perform? I would love to hear some thoughts on such a system. I know it sounds dumb but I was just asking the question because I'm all about racing and I was thinking of ways to drop some weight.
