Porsche RENNKRAFT Modular Headers With Catalytic Converters For Porsche 987.2 Boxster (2009-2012), 987.2 Cayman (2009-2012) Models.

These Fabspeed US PATENTED modular headers are the perfect solution for any 987.2 Cayman or Boxster owner. Our United States patented RENNKRAFT modular design features a quick-release V-band connector, allowing you to easily swap between our German-made HJS 200-cell catalytic converters and cat bypass "straight pipes" for track use ONLY. RENNKRAFT, translated from German, means "race power." These patented headers offer true street and racetrack functionality in an innovative, precision engineered package. Furthermore, if the HJS catalytic converters EVER fail due to poor gasoline, backfires, or super high mileage, the Patented Design allows for a simple NEW HJS German catalytic converter section to be installed.

SOUND:

Equipped with HJS German HD trimetallic 200-cell catalytic converters, you'll experience a sportier, more aggressive exhaust note with a much more exciting sound. Higher frequency tones are more defined, and off-throttle burbles are more robust and transparent. With the cat bypass pipes installed, FOR RACE TRACK USAGE ONLY, you have the ultimate system for Road Racing Competition use only. The volume isn't overbearing, but the sound is very aggressive and race-bred, completely changing the character of the car.
