Installed Milltek Resonated Valved Exhaust on the RS4
 

I bought this from a fellow member who had custom valves (through the factory sport mode) and i can bypass the mufflers with a push of a button or run full exhaust. I can't even explain how much the car picked up off a roll over 50mph. The car pulls so so much harder. I am thrilled!! I will post some vids tomorrow of no muffler and with muffler. The great thing is that even at 70mph with the valves open there is no drone whatsoever.

My old exhaust! :) Glad you like it, it was a steal for $570 ;)
