730HP Audi RS6-R ABT with Milltek Exhaust INSANE Sound on the Dyno!

Just listen to this insanely loud Audi RS6-R C7 ABT fitted with Milltek catless exhaust system making some dyno runs. The sound coming out of the 4.0 TFSI Twin-Turbo V8 engine is just INSANE! Special thanks go to the guys at BIESSE racing for making this possible: Follow me also on: - Facebook: - Google : NM2255 - Twitter: - 2nd Car Channel:
