Phoenyx Design Race Headers No Catalytic Converters No Tune (20132016 Porsche 991.1 GT3)
Catless Race Headers for Porsche 991.1 GT3
The Phoenyx Design Race Headers No Catalytic Converters for the 20132016 Porsche 991.1 GT3 are engineered for drivers who want maximum exhaust flow, reduced backpressure, and uncompromised track performance. By eliminating the restrictive factory catalytic converters, these race headers significantly improve exhaust scavenging, throttle response, and high-RPM power deliveryexactly where the GT3 lives.
Manufactured from 100% high-quality T304 stainless steel, these headers are built to handle extreme exhaust temperatures and sustained track abuse. Precision TIG welds ensure long-term durability and structural integrity, while the heat-stamped integrated heat shielding helps manage under-hood temperatures during aggressive driving.
This system installs as a direct bolt-on replacement and includes all necessary mounting hardware for proper factory-style fitment. The design is also 100% reversible, allowing you to return the vehicle to stock if desired. No tuning is included, though racing software is strongly recommended to maximize performance and manage fault codes.
