MTM already modifies the Audi A7Well... that was fast. MTM managed to already get a hold of an A7 and tweak it. The most obvious difference is a modified rear diffuser which accepts a quad exhaust. Wheel spacers and MTM rims were installed as well. A lowering module designed to work with the stock suspension is in the works. A tune for the 3.0 TDI in this A7 was added which boosts horsepower by about 40 to 285.
