Made specifically for Mclaren 720S


Project Gamma catless downpipes for the 720S models feature a stainless steel v-band to pipe transition that is machined with CNC to precision.  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 catless downpipes are handcrafted to extreme rust resistance using 304 Stainless Steel.


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


- 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 Mclaren models:

- 2018+ Mclaren 720S Coupe

- 2019+ Mclaren 720S Coupe
