Fabspeed Porsche 997.2 Carrera RENNKRAFT® Modular Headers with HJS Catalytic Converters (2009-2011)

Patented RENNKRAFT modular headers deliver race-bred performance for 2009-2012 Porsche 997.2 Carrera models worldwide, including Cayman R and Boxster Spyder. CNC mandrel-bent T304L stainless steel construction provides +25HP and 20 ft-lb torque gains with HJS 200-cell cats installed. V-band design enables fast swaps to cat bypass pipes for track use only, protecting cats from racing abuse.

Key Features

  • Patented RENNKRAFT Design: US-patented quick-release V-band clamps allow instant swaps between HJS German HD tri-metallic 200-cell cats and straight-pipe bypass for track-only racing, extending cat life during competition.
  • Power and Weight Savings: Delivers +25HP and 20 ft-lb torque over stock with 2 lbs (0.9 kg) lighter sport cats or 7 lbs (3.2 kg) lighter bypass versus factory headers, using F1-style high-velocity merge collectors for superior scavenging.
  • HJS Catalytic Converters: Imported German EMITEC 200-cell EURO 6 homologated cats flow 93% of a 2.5-inch straight pipe, ensure EPA compliance, prevent check engine lights with no ECU tune needed, and produce aggressive exhaust sound with defined high tones and robust burbles.
  • Precision Engineering: Built from 3D scans of OEM headers for perfect bolt-on fitment, compatible with any aftermarket exhaust designed for factory headers, hand-crafted with 25+ years of Porsche experience.
  • Track-Ready Versatility: Cat bypass option for road racing competition only transforms sound to race-bred aggression without excessive volume, while HJS cats maintain street legality and performance.

Product Notes

  • Cat bypass pipes for track use only to avoid catalytic converter damage from racing conditions.
  • HJS cats warranted against failure from poor fuel or backfires via simple modular replacement.
  • For RENNKRAFT system licensing, call 215-646-4945.

Installation Notes

  • Professional installation recommended.
  • Simple DIY bolt-on with video guide on Fabspeed website, no ECU tune required.
  • Bolts directly to factory locations, fits all aftermarket exhaust systems compatible with OEM headers.

Headers & Manifolds

Headers & Manifolds

Performance headers and exhaust manifolds are among the most effective bolt-on upgrades for improving exhaust scavenging, increasing horsepower, and giving your engine a more aggressive exhaust note. Whether you're building a street machine, a track car, or a diesel work truck, the right header or manifold set unlocks real performance gains across the RPM range. Popular Upgrades Top-selling header and manifold products include long-tube headers from BBK and Kooks for V8 muscle cars and trucks, stainless steel shorty headers from Stainless Works for tight engine bay fitments, high-flow cast iron exhaust manifolds for diesel platforms from BD Diesel and ATS Diesel, and turbo manifolds from aFe Power and Invidia for forced-induction builds requiring optimized turbo positioning. What is the difference between long-tube and shorty headers? Long-tube headers route exhaust primaries farther down the chassis before merging at a collector, which improves mid-range and top-end power but requi...
