Mercedes-Benz GT63 | E63 Downpipes and Project Gamma Tune Package

Project Gamma downpipes for the AMG GT63 / GT63S models feature a 4 to 3” construction along with a stainless steel v-band to pipe transition that is machined with CNC to precision. Our downpipes are the best bang for your buck mod available for your AMG GT63 / GT63S with gains from 50 Horsepower and 60 Torque when tuned. Rather than necking down closer to the turbos like most of our competitors, our downpipes present a full 3D design up to the last inches proving a greater increase in flow. These downpipes allow for cooler temperatures in the engine bay with the addition of heat shielding. Project Gamma downpipes are handcrafted to extreme rust resistance using 304 Stainless Steel.

Project Gamma Tune

With the Project Gamma custom tune, the vehicle will have power gains up to 180 HP with supporting mods.

The customer will receive a handheld device with the Project Gamma Tune and the factory tune. The vehicle can be flashed at any time.
