Your exhaust is not that loud, go to a reputable muffler shop and tell them what you want and they will be able to complete your setup. Give me a minute and I will post a video of my exhaust for you guys to judge.
It really actually does That vid was not a good representation of what it sounds like IRL. Also when sitting parked and actually under load it sounds totally different. When a buddy pickled up a newsed M this summer, he and I went for a drive and our cars sounded almost identical

Superhiro, did you ever try an H-pipe?
Nope, but the X-Pipe on the Magnaflow should help.

I tried looking into just replacing the forward resonator with a manaflow unit, but that didnt work out (details and original idea found here: http://forum.e46fanatics.com/showthread.php?t=700120).

Did you ever get an Ikon?
So I kept me eyes open for a used Ikon and never saw one. But thankfully the Magnaflow with built in X-Pipe finally was produced. So I just ordered it and we'll see if it helps
