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

These modular headers are the perfect solution for any Cayman or Boxster. Our patented RENNKRAFT® 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. 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.
