I'm trying to identify the exhaust system that Dialynx fitted to my S4 Avant? It came from TAP. It's not a Scorpion or Stebro, has a *single* muffler and dual 3" upswept DTM-style tailpipes. Any idea of the original manufacturer, there are no obvious signs? It does sound awesome! Anyone want to buy an Alpine 3+6 CD system. I have all the music I need now! :-) Regards, Malcolm
