So I installed the RS6 sport exhaust on my 4.2 today and it sounds insane. This is the way the car should have sounded. Also i had bought RS6 Upper Lower and side grills a while ago and installed them a while ago but never got around to making the sides grills work. So i got creative with my dremel and cut out my stock grills and my RS6 grills and hot glued them into the stock ones. Check my account for some pics. Also got some H&R Coilovers in my garage that should be going on this week.
