Loud tuned Audi RS6 with full Miltek Exhaust. All the way from turbo back. Main part/Sound part of the video starts a little ways in, where we mounted a microphone to the back of the RS6 to try and capture some high quality sound clips. Unfortunately the mic kept clipping even with everything turned down as low as it goes. But i think you get the idea. Absolute beast of a car. 4L V8 Twin turbo straight pipe
