  • Fits all Porsche 981 Cayman GT4 / Boxster Spyder vehicles (2015-2016)
  • Constructed from CNC mandrel-bent T304L stainless steel
  • Impressive power and performance gains
  • Save 2 lbs / 0.9 KGs with Sport Cats and 7 lbs / 3.2 KGs with Cat Bypass compared to the factory headers
  • Modular design that uses a V-band clamp so one can quickly swap between cats and cat bypass
  • With the RENNKRAFT® system, you can quickly install our QUICKTRACK™ cat bypass pipes for Racing and all out Race track-only competition events
  • The RENNKRAFT® system has been awarded a US Patent and is the only system of its kind in the world
  • Switching to cat-bypass for track events prevents catalytic converter degradation during all out competition racing abuse
  • F1 style high velocity merge collectors
  • Designed from 3D scans of the OEM headers so we can achieve perfect bolt-on fitment
  • We use German-made HJS HD tri-metallic 200-cell EURO 6 homologated catalytic converters for the best performance and reliability
  • We use the largest catalytic converters that will fit in the factory location for maximum flow
  • Flows 93% of a 2.5 in straight pipe
  • Optimized for maximum performance with NO catalyst generated check engine light, guaranteed, when Sport Cats are installed
  • No ECU tune required
  • Will fit with any brand of aftermarket exhaust system designed to work with the factory headers
  • 25+ years of air-cooled and water-cooled Porsche experience went into our design for these hand-crafted headers
  • Simple DIY (Do-It-Yourself) bolt-on installation, no cutting or welding required
