I looked through the unofficial A6/S6 exhaust thread, and it seemed it was full of 2.7TT and 4.2 exhaust. Was hoping to find some users with the 3.0 and custom exhaust. Stock is way to quiet for me, and I want to liven it up some. If youve done something custom with yours, please post it up. I found a few videos of Miltek and another brand's cat back, but looking for different setups.
