Modular Street and Racing Headers And HJS Catalytic Converters For Porsche 718 Boxster Spyder (2020-2023), and 718 Cayman GT4 (2020-2023) Models.

POWER:

• Optimal Mid-Range Design: Extensive dyno testing determined that mid-length headers provide the best power gains across the entire RPM band.
• Sport Cat Gains (No Tune): Achieved 31 wheel horsepower (whp) and 19 ft-lbs of torque at 7400 RPM compared to a stock car.
• Cat Bypass Gains (No Tune): Achieved even higher gains of 33 whp and 24 ft-lbs of torque at 7200 RPM compared to a stock car.
• Significant Crank Horsepower Increase: Represents a gain of 33 HP at the crank with Sport Cats and 36 HP at the crank with Cat Bypass Pipes.
• Improved Peak Horsepower: Peak horsepower increased from the baseline of 383 whp to 405 whp with HJS Sport Cats and 409 whp with Cat Bypass Pipes.

FEATURES:

• Impressive Dyno-Proven Gains: Delivers significant power increases of 31 whp and 19 ft-lbs of torque with Sport Cats, and 33 whp and 24 ft-lbs of torque with Cat Bypass installed.
• Weight Reduction: Saves 2 lbs / 0.9 KGs with Sport Cats and 7 lbs / 3.2 KGs with Cat Bypass compared to the factory headers.
• Modular and Swappable Design: Features a V-band clamp for quick and easy swapping between catalytic converters and cat bypass pipes.
• QUICKTRACK System: The patented RENNKRAFT system allows for rapid installation of QUICKTRACK cat bypass pipes specifically for racing and track-only events.
• Catalyst Protection for Track Use: Switching to cat bypass for track events prevents potential degradation of the catalytic converters during intense racing.
• Optimized Exhaust Flow: Incorporates F1-style high-velocity merge collectors for improved exhaust scavenging.
• Precise OEM Fitment: Designed using 3D scans of the OEM headers to ensure perfect bolt-on fitment.
• Premium Catalytic Converters: Utilizes German-made HJS HD tri-metallic 200-cell EURO 6 homologated catalytic converters for optimal performance and reliability.
• Maximum Flow Catalytic Converters: Employs the largest catalytic converters that fit in the factory location to maximize exhaust flow.
• High Flow Rate: The 200-cell catalytic converters flow at 93% of a 2.5-inch straight pipe.
• No Check Engine Light (Sport Cats): Optimized for maximum performance without triggering catalyst-related check engine lights when Sport Cats are installed.
• No ECU Tune Required: Designed to deliver these power gains without the need for an ECU tune.
• Not Street Legal: NOT EPA or CARB Certified and should not be used on street-driven vehicles.
• Universal Exhaust Compatibility: Will fit with any aftermarket exhaust system designed to work with the factory headers.
• Made in the USA: Built entirely in-house at Fabspeed Motorsport USA in Fort Washington, PA.
• Expert Development: Developed in collaboration with HJS Emissions Technology, leveraging over 25 years of Porsche experience.
• Premium Construction: Constructed from CNC mandrel-bent T304L stainless steel for durability and optimal flow.
• Easy Bolt-On Installation: Simple Do-It-Yourself bolt-on installation process that requires no cutting or welding.
