Project Gamma downpipes for the C300  model features 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 C300 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. Ceramic coating is offered to reduce temperature in the engine bay.  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 Note: This product requires installation by a technician and will need tune recalibration to avoid cel light.   This product fits the following Mercedes-Benz models: - 2014-2020 Mercedes-Benz (W205) C300  (M274)
