Fabspeed 2015-2016 Porsche Boxster Spyder/Cayman GT4 (981) RENNKRAFT™ Modular Headers with HJS Catalytic Converters

These modular headers are the perfect solution for any Cayman or Boxster. Our modular design features a quick release V-band connector that allows the owner to easily swap between our German made HJS 200 cell cats and a cat bypass “straight pipes” for track use (patent pending). Rennkraft, translated from German is “race power”. These unique headers offer true street and racetrack functionality in an innovative precision engineered package.

SOUND:

Equipped with our 200 cell cats, you will get a louder exhaust note with a much more raw sound. Higher frequency tones are more defined, and off throttle burbles are more robust and transparent. With the cat bypass pipes installed, you’re in store for a sound much more akin to a 911 CUP car than a Porsche street car. The volume isn’t overbearing, but the sound is very aggressive and race bred. It totally changes the character of the car.

FEATURES:

• 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
