Porsche 991 Carrera RENNKRAFT® Modular Headers with HJS Catalytic Converters (2012-2016)

These modular headers are the perfect solution for any Porsche 911. Our United States 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 ONLY. RENNKRAFT®, translated from German is “race power”. These unique headers offer true street and racetrack functionality in an innovative precision engineered package. In addition, if the HJS catalytic converters EVER fail because of poor gasoline, back-fires, super high mileage the Patented Design allows for a simple NEW HJS German catalytic converter section to be installed. HJS German catalytic converters are European homologated and European certified and US EPA compliant!

SOUND:

Equipped with HJS German HD tri-metallic 200 cell cats, you will get 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.
