REN NKRAFT Modular GTLM Exhaust Package

The Fabspeed RENNKRAFT Modular GTLM Exhaust Package is a complete, headers-to-tips exhaust solution engineered for the Porsche 992 GT3 and GT3 RS models from 2022 onwards. This system leverages over 25 years of Fabspeed's Porsche exhaust design expertise and advanced manufacturing techniques to deliver the most powerful, emissions-compliant exhaust system available. The system features precisely engineered equal-length headers with Burns Stainless Formula 1/Indy car-style high-velocity merge collectors, constructed from T321 stainless steel Mil Spec tubing with a 2.75-inch (70mm) diameter. Investment cast stainless steel flanges ensure maximum flow and strength, while CNC mandrel-bent tubing maintains optimal exhaust gas velocity. At its core are German-made HJS HD tri-metallic 200-cell EURO 6 homologated catalytic converters, designed for high performance and reliability. A key innovation is the patented RENNKRAFT™ modular system, which uses quick-release V-band clamps. This allows for quick and easy swapping between the included catted configuration for street use and optional cat-bypass pipes for track events, preventing catalytic converter degradation during intense competition. This exhaust system is characterized by an aggressive, race-bred sound that includes pops and gurgles at lower RPMs and a scream at redline. However, this comes at the expense of some interior drone and reduced day-to-day livability. For performance, the system is claimed to add a maximum of 31 WHP and 39 ft-lbs of torque at 4250 RPM (35 HP at the crank), with gains of over 20 WHP sustained from 6000 RPM to redline. It also offers a significant weight saving of 18 lbs (8.2 kgs) compared to the stock OEM system.
