Fabspeed RENNKRAFT Modular Headers with Sport Cats for 991.1 Porsche 911 Carrera, GTS and S [FS.POR.991.MH.SC/FS.POR.991.MH.SCCB]

Fabspeed RENNKRAFT Modular Headers with Sport Cats for 991.1 Porsche 911 Carrera, GTS and S [FS.POR.991.MH.SC/FS.POR.991.MH.SCCB]

The modular headers are the perfect solution for any Porsche 911. The United States-patented RENNKRAFT modular design features a quick-release V-band connector, allowing owners to easily swap between the German-made HJS 200-cell cats and race pipes designed for track use only. “RENNKRAFT,” translated from German, means “race power.” These unique headers offer both street and racetrack functionality in an innovative, precision-engineered package. Additionally, if the HJS cats fail due to poor gasoline, backfires, or high mileage, the patented design allows for easy installation of a new HJS German section. HJS German catalytic converters are European homologated, European certified, and US EPA compliant.

Sound

• With the sport cats installed, the exhaust note becomes sportier and more aggressive, offering a much more exciting sound. Higher frequency tones are sharper, and off-throttle burbles are more robust and transparent. When the race pipes are installed, the volume is aggressive yet not overwhelming, delivering a race-bred sound that completely transforms the car’s character.
