Hey guys, so first off I hope this is the right spot to ask about custom exhaust fabricating. I currently have a 3.2 A6 with the rear mufflers and al resonators removed. Its sounds good. Loud as hell. And burbly. But a little raspy at times. I want a deeper "bellow" sound. So this is what I had planned for next spring.. 3inch piping from the cats back, into single chamber muffler. No X pipe. Keeping the H. Would the increase diameter and some minimal muffler make the intended note that I want? I just want insight in someone who knows exhaust technology better than I do. Thanks.
