Description
The modular headers for the Porsche 911 feature a patented RENNKRAFT® design with a quick-release V-band connector, allowing easy swaps between HJS 200-cell cats and race pipes for track use. The system offers both street and racetrack functionality, with the option to replace HJS cats if needed, and the HJS cats are European homologated, certified, and US EPA compliant.
