Project Gamma downpipes for the 600LT models feature a stainless steel v-band to pipe transition that is machined with CNC to precision. 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 200HP. Flames and burbles can be added.
