Phoenyx Design Race Headers 200 Cell High-Flow Catalytic Converters Tune Included (20132016 Porsche 991.1 GT3)
High-Flow Catted Race Headers with Included GT3 Tune
The Phoenyx Design Race Headers with 200 Cell Euro 6 high-flow catalytic converters are engineered for Porsche owners who want a serious performance upgrade for their 20132016 Porsche 991.1 GT3 while retaining a high-performance catalytic converter design. These headers significantly improve exhaust flow over the restrictive factory units, delivering stronger throttle response, increased horsepower, and a sharper powerband across the RPM range.
Constructed from 100% high-quality T304 stainless steel, these headers are built to withstand extreme heat and track-level abuse. Precision TIG welding ensures long-term durability, while the heat-stamped integrated heat shielding helps manage under-engine temperatures during aggressive driving. The included 200 cell Euro 6 sport high-flow catalytic converters strike the ideal balance between performance and exhaust control for track-focused builds.
This package includes a GT3-specific performance tune designed to fully optimize the exhaust upgrade. The tune refines fueling, ignition timing, and throttle mapping to safely unlock additional power and torque. Tuning instructions are emailed after purchase. Installation is a direct bolt-on, includes all required mounting hardware, and remains 100% reversible if you ever need to return the car to stock.
