No one has the car yet, let alone an exhaust. Are you referring to a B5 S4?
If so, hop over to that forum. <ul><li><a href="https://www.audiworld.com/forum/s4.html">B5 S4</a></li></ul>

B6 Milltek S4 Exhaust...
AmD in the UK has seen a 20hp gain on the new S4 with the new Milltek catback exhaust. Dyno charts to follow. That's exciting news for everyone. We may even have a system on display at the NE Audi Show and Waterfest. What's next after that? Testing of new high-flow cats. -Pete, Strat
