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.

The product you see has been Ceramic Coated. To protect your engine bay from possible heat damage please purchase our Ceramic Coating add-on before checking out, otherwise your downpipes will just come polished.

Features:

• Major increases in power throughout the powerband
• Improved turbo and throttle response
• Elimination of turbo lag
• Exotic exhaust note
• Precise and proper fitment using factory heat shielding
