Fabspeed Performance Package for 991.1 Porsche 911 GT3 & GT3 RS

The Fabspeed Performance Package for the 991.1 Porsche 911 GT3 & GT3 RS provides a noticeable increase in horsepower and torque across the RPM range, significantly enhancing both performance and driving experience. Constructed from high-quality 14-16 gauge, CNC mandrel-bent T304L stainless steel, the package includes hand TIG-welded and backpurged components crafted by Fabspeed artisans. CAD-designed and incrementally tested on a Dynojet, the system features sport headers with 200-cell HJS high-flow sport cats, along with high-velocity 3-into-1 pyramidal investment cast merge collectors for optimized exhaust scavenging. The race header system is engineered using Burns Stainless proprietary X-design parametric engine/exhaust design software, ensuring peak performance. Additionally, the side muffler bypass replaces the restrictive factory mufflers, improving exhaust flow and saving 34lbs. Designed for easy installation, the system complies with emissions standards and the factory Porsche warranty while guaranteeing maximum performance with no check engine light.
