High-Flow Catted Racing Downpipe with Tune for Porsche 718 Cayman
The Phoenyx Design Racing Downpipe with 200 Cell Euro 6 Sport High Flow Catalytic Converter and Tune Included for the Porsche 718 Cayman and Cayman S is engineered to deliver a major step up in exhaust flow, throttle response, and overall performance. By replacing the restrictive factory downpipe with a motorsport-grade high-flow Catalytic Converter, this system helps unlock significant horsepower and torque gains while maintaining strong exhaust velocity.
Constructed from 100% high-quality T304 stainless steel, this downpipe is built to handle extreme exhaust temperatures and sustained high-performance driving. Precision TIG welds provide exceptional strength and longevity, while the heat-stamped integrated heat shield helps control underbody temperatures during aggressive street driving and track use.
This setup is designed as a direct bolt-on upgrade and includes all necessary mounting hardware for factory-style fitment. The system is also 100% reversible, allowing you to return the vehicle to stock at any time. A performance tune is included and tailored specifically for Cayman and Cayman S models to maximize gains and drivability.
