Product Description

 

 

The Fabspeed RENNKRAFT® Modular Street & Racing Headers are an elite performance exhaust upgrade for the Porsche 992 GT3 and GT3 RS (2022 +) built to deliver real horsepower and torque gains, improved engine sound, and dual-purpose functionality for both street and track use. These headers utilize Fabspeed’s U.S. patented RENNKRAFT® modular design, which allows you to quickly switch between high-flow HJS catalytic converters for emissions-friendly road use and cat-bypass link pipes for uncompromised track-only performance. Precision engineered using 3D laser scans and developed with German HJS technology, this header system elevates the 4.0 L flat-six’s breathing efficiency while enhancing the GT3’s distinctive exhaust note.

Fitment Notes

  • Designed for Porsche 911 992 GT3 and GT3 RS models from 2022 onward.

  • Direct bolt-on fitment engineered from OEM 3D scans — no cutting or welding required.

  • Street configuration uses high-flow HJS catalytic converters to avoid CEL and support emissions compliance (outside EU/GPF-monitored cars without a simulator or tune).

  • Track configuration with included cat-bypass pipes is intended track-only use (may trigger codes and is not emissions legal).

  • May delete the GPF on EU/GPF-monitored vehicles unless paired with an appropriate simulator or tune.

Included

  • Modular RENNKRAFT® long tube headers tailored for the 992 GT3/GT3 RS.

  • HJS German-imported 200-cell catalytic converters (street use).

  • Cat-bypass QUICKTRACK™ link pipes for track configuration.

  • Quick-release V-band hardware for modular switching.

  • Mounting hardware and installation instructions for bolt-on setup.

Product Specs

  • Material: CNC-mandrel-bent T304L stainless steel for durability and heat resistance.

  • Configuration: Modular long tube header system with quick-swap HJS cats and cat-bypass pipes.

  • Gains (sport cats): Typically ~+19 HP / +20 lb-ft torque at the crank and ~16 whp / ~20 ft-lb at the wheels over stock.

  • Gains (cat-bypass): Up to ~+23 HP / +26 lb-ft torque at the crank and ~19 whp / ~26 ft-lb at the wheels.

  • Weight Savings: Approximately 6 lbs (2.7 kg) lighter than factory headers.

  • Sound Character: More aggressive, race-bred tone with robust burbles and deceleration sound, especially with cat bypass.

  • Warranty: Backed by Fabspeed’s Lifetime Warranty (terms vary by reseller).

Product Features

  • US-Patented RENNKRAFT® modular design lets you quickly swap between emissions-compliant and race-only configurations.

  • High-flow HJS catalytic converters deliver strong power gains with minimal check-engine light risk when used properly.

  • Cat-bypass link pipes allow uncompromised flow and sound for track sessions.

  • Long tube header geometry enhances exhaust scavenging and mid-range torque.

  • Precision engineering with F1-style merge collectors improves flow dynamics and sound quality.

  • CNC mandrel construction with premium stainless steel ensures strength, heat tolerance, and durability
