In today's video you'll see a sound comparison between a stock 2020 Audi RS6 C8 Avant, Akrapovic and Milltek exhaust with ECU remap by BiesseRacing. This beast is powered by a 4.0 liter V8 TFSI engine that ended up making some pretty impressive numbers on the dyno!


Special thanks go to the guys at BIESSE racing for making this possible:   / biesseracing
