Phoenyx Design Racing Downpipes No Cat, No Tune (20192023 Porsche 718 Cayman GT4)
Catless Racing Downpipes for Porsche 718 Cayman GT4
The Phoenyx Design Racing Downpipes are engineered to unleash unrestricted exhaust flow and aggressive performance from the Porsche 718 Cayman GT4. Designed for track-focused applications, these catless racing downpipes remove the restrictive factory catalytic converters to improve throttle response and deliver noticeable gains in horsepower and torque.
Each downpipe is fabricated from 100% high-quality T304 stainless steel and features precision TIG welds along with an integrated heat-stamped heat shield to withstand extreme exhaust temperatures during hard driving. This motorsport-grade construction ensures durability, reliability, and consistent performance under demanding track conditions.
This system is offered as a no-tune racing solution and is 100% reversible, allowing the vehicle to be returned to stock at any time. All necessary mounting hardware is included for a clean, direct bolt-on installation. Due to catalytic converter removal, racing software may be recommended to manage fault codes.
