My exhaust is a Milltek resonated with added pre-muffler (yet post-resonator) "dump" valves that work off of the factory Sport-button. (you just extend the vacuum line to reach a bit farther) They simply dump to the ground via flanges we added... creating a more "evil" sound when engaged and on initial startup, yet not raspy/ricey/obnoxious. My neighbors love that I can turn it down, yet still romp by them when asked to!

I have my stock exhaust (which you can have) but it'd be much easier just to do a straight-up swap with somebody on one day and get some cash back out of it.

More details available via PM.. let me know if you're interested. I'm just south of Boston, MA and can also meet you in Connecticut or Western Mass.

I have other stuff available as well... European flat-bottomed steering wheel with actual RS4 airbag & harness (not an A8 airbag), OEM RS4 wheel (as a spare) with tire, SD cards for the RNS-E (2GB and 4GB, both used thoroughly), spare grille without aluminum ring (missing), OEM European front-plate holder, bumper-reflectors (orange) colormatched to silver mirrors, etc.

Picture of one of the valved-bypass dumps below! Sounds great. Like stock but more free-flowing and loud. But not too loud, and controlled by the Sport button.
