Project Gamma Stainless Steel Downpipes 


Made specifically for Mercedes-Benz S63 AMG 4.0amg engine. 


Project Gamma downpipes for the S63 AMG 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 S63 AMG 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.


Ceramic coating is offered to reduce temperature in the engine bay. 

 ******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.*******

Note: This product requires installation by a technician and will need tune recalibration to avoid cel light.
