Project Gamma downpipes for the C63 models feature a 4” 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 C63 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. Project Gamma's Mercedes C63s downpipes are handcrafted to extreme rust resistance using 304 Stainless Steel.
