U.S. based auto tuners RENNtech have just released a sweet video of an Akrapovic titanium exhaust system for the Mercedes-Benz C63 AMG. The new exhaust system reduces weight by 43 pounds, increases horsepower by 12 and torque by 16 pound-feet. The Akrapovic exhaust system also increases the Mercedes C63 AMG’s bad-assery by 2 notches compared to a regular C63.
