Decent exhaust on B8 S4 ?
 

About to order the S4 and every review I have read talks about how great the car is but how weak or unsatisfying the sound is. Being that this car has been out in Europe for a while now, what exhausts are out there (available in the US)that look stock but give the car a deeper more interesting sound ?

Would expect a Milltek exhaust soon.

Audio clip from YouTube I found of a new intake being worked on by Stratmosphere sounds like, if you want to hear your supercharger:

They are also working with Milltek on exhaust(pictured here)
