Porsche Rennkraft Modular GTLM Exhaust System For Porsche 992 GT3 (2022-2025), 992 GT3 RS (2023-2025) Models.

Rennkraft Modular GTLM Exhaust System, meticulously engineered to be the most powerful emissions-compliant exhaust solution available for all 992 GT3 and GT3 RS models worldwide. Leveraging over 25 years of Porsche exhaust design expertise and cutting-edge manufacturing techniques, this patented RENNKRAFT system offers a modular design for ultimate performance and versatility.

For the catalytic converters and rear section, we implemented extra-large 200-cell HJS German-imported high-flow racing catalytic converters from EMITEC. These highly efficient cats allow for maximum "Clean and Green Performance," with dyno testing showing minimal peak WHP difference compared to a catless configuration. To further enhance flow, we incorporated our signature investment-cast CAD-designed 70mm (2.75") X-pipe, which demonstrated significant gains in the 3-6K RPM range compared to simpler designs.

The patented RENNKRAFT system features a modular design with quick-release v-band clamps (patent pending), enabling easy swapping between the emissions-compliant catted configuration and cat-bypass pipes for off-road endurance racing events. This flexibility ensures optimal performance for both street and track use while safeguarding the catalytic converters from degradation during intense racing.

Performance Gains:

Experience maximum gains of +37 HP at the crank (31 WHP) and 39 lb-ft of torque at 4250 RPM. This system delivers usable power across the entire RPM band, with gains of over 20 WHP sustained from 6000 RPM to redline. Feel the significant power enhancement that over 30 years of air-cooled and water-cooled Porsche expertise from Fabspeed Motorsport delivers to your GT3.

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).
• Adds 31 WHP and 39 lb-ft of TQ at 4250 RPM (37 HP at the crank).
• Saves a significant 18 lbs / 8.2 kg compared to the stock factory Porsche OEM system.
• Features equal-length headers with Burns Stainless Formula 1/Indy car style high-velocity merge collectors for optimized exhaust scavenging.
  
• Utilizes springs for collector retention to accommodate thermal expansion and increase durability.
• Fabricated from T321 stainless steel Mil Spec tubing to ASME specifications.
• Incorporates CNC mandrel-bent tubing with a 2.75in / 70mm diameter for maximum flow.
• Features CAD-designed investment-cast stainless steel flanges for maximum flow and strength.
• Employs a modular design with V-band clamps for quick and easy swapping between catted and cat-bypass configurations.
  
• Switching to cat-bypass for track events prevents catalytic converter degradation during all-out Endurance Racing competition racing abuse
