200 Cell Euro 6 Sport Catted Racing Downpipes for Porsche 718 Cayman GT4 RS
The Phoenyx Design Racing Downpipes with 200 Cell Euro 6 Sport High Flow Catalytic Converters are engineered to deliver aggressive performance gains for the Porsche 718 Cayman GT4 RS while retaining a high-flow sport-catted configuration. Designed for high-RPM, track-focused driving, these downpipes improve exhaust efficiency, sharpen throttle response, and support meaningful gains in horsepower and torque.
Each system is constructed from 100% high-quality T304 stainless steel and features precision TIG welds paired with an integrated heat-stamped heat shield to withstand extreme exhaust temperatures generated during hard driving and sustained track sessions. The 200-cell Euro 6 sport Catalytic Converter significantly reduces restriction compared to factory components while maintaining a race-inspired exhaust design.
This setup 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 installation. Due to catalytic converter modification, racing software may be recommended to manage fault codes.
