Porsche Rennkraft Modular Sport Headers with HJS Catalytic Converters For Porsche 992 GT3 (2022-2025), 992 GT3 RS (2023-2025) Models.

Introducing the Rennkraft Modular Headers with HJS Catalytic Converters, the ultimate solution for street-driven 992 GT3 and GT3 RS models worldwide. Our U.S. Patented RENNKRAFT modular design features a quick-release V-band connector, allowing owners to effortlessly switch between our German-imported EMITEC HJS 200-cell Euro 6 homologated catalytic converters and our QUICKTRACK "link pipes" for dedicated track use.

Rennkraft, meaning "Race Power" in German, embodies the true street and racetrack functionality of these innovative, precision-engineered headers. Fabspeed Motorsport USA was the pioneering company to 3D laser scan, design, patent, and dyno-develop these premium headers in collaboration with HJS Germany and renowned Porsche engine builders. We confidently guarantee that there is no superior header available for your 992 GT3 worldwide.

SOUND:

Leveraging over 29 years of air-cooled and water-cooled Porsche expertise, Fabspeed Equipped with our super-premium HJS German 200-cell catalytic converters, you'll experience a more aggressive CUP car-style exhaust note with a significantly more raw Flat 6 sports car sound. Higher frequency tones are more pronounced, and deceleration burbles are more robust and distinct.

Extensive dyno development has allowed us to identify the optimal header length and diameter. Compared to a stock car with no tune, our Sport Cats yielded gains of +19 HP / 16 whp and 20 lb-ft of torque, while the Cat Bypass pipes resulted in +23 HP / 19 whp and 26 lb-ft of torque at the crank. Peak horsepower also increased from our baseline of 452 whp to 461 whp with our HJS Sport Cats and 468 whp with Cat Bypass Pipes. As clearly demonstrated, EMITEC HJS German tri-metallic catalytic converters deliver exceptional CLEAN and Green Power. Refer to our dyno graph for detailed performance data.

FEATURES:

• Fits all Porsche 992 GT3, GT3 RS Models worldwide (This system does delete the GPF on EU cars and will cause a check engine light for a monitored GPF system unless a simulator or tune is used).
• Impressive dyno-proven power gains of 20 horsepower and 25 lb-ft of torque at the crank (16 whp and 20 lb-ft of TQ with Sport Cats, and 19 whp and 26 lb-ft of TQ with link comp pipes installed).
• PATENTED SYSTEM WORLDWIDE: The world's first dual-use STREET and RACETRACK Competition system.
• Saves 6 lbs / 2.7 kg compared to the factory headers.
• Modular design with a V-band clamp allows for quick swapping between catalytic converters and competition link pipes for racing, preserving your HJS catalytic converters from the harsh conditions of endurance racing and long-term closed-course competition.
• Modular patented design also allows for HJS catalytic converter replacement as needed.
• The cat bypass pipes are 100% NOT intended for street usage and are designed to bypass emissions controls for off-road track use only.
• Constructed from CNC mandrel-bent T304L stainless steel, lost wax precision investment cast inlet flanges, and CAD-designed CNC flanges.
• Switching to cat-bypass for track events prevents catalytic converter degradation during all-out competition racing abuse.
• The RENNKRAFT system allows for the quick installation of our QUICKTRACK cat bypass pipes for racing and track-only competition events.
• Features F1-style high-velocity triangular merge collectors with a merge spike for maximum exhaust scavenging.
