Project Gamma downpipes for M3 | M4 (G80/G82) models feature a 3.5” 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 M3 | M4 (G80/G82) 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 downpipes are handcrafted to extreme rust resistance using 304 Stainless Steel.
