Fabspeed 2021-2022 Porsche 911 GT3 (992) RENNKRAFT™ Modular Street and Racing Headers with HJS Catalytic Converters

These modular headers are the perfect solution for any street driven 992 GT3. Our RENNKRAFT™ modular design features a quick release V-band connector that allows the owner to easily swap between our German Imported  HJS 200 cell Euro 6 homologated catalytic converters and QUICKTRACK™  “link pipes” for track use Patent pending.  Rennkraft, translated from German is “Race Power”. These unique headers offer true street and racetrack functionality in an innovative precision engineered package.

SOUND:

Fabspeed Motorsport USA, utilizing 25+ years of Air-cooled an watercooled experience has made the 992 GT3 sound incredible with these high flowing headers. Equipped with our HJS German super premium  200 cell cats, you will get a more aggressive CUP car style exhaust note with a much more raw sound. Higher frequency tones are more defined, and deceleration burbles are more robust and transparent. With the cat bypass pipes installed, the GT3 turns into a motorsport bred monster. At [art throttle the volume isn’t overbearing, but the sound is very aggressive and race bred. With the stock muffler in place, there is no drone what-so-ever with maximum clean and green emissions power. Innovation NOT Imitation with Fabspeed Motorsport USA.

POWER:

After extensive dyno development we found the optimal header length and diameter. With no tune, compared to a stock car we gained 16 whp and 20 ft/lbs of TQ with the Sport Cats and 19 whp and 26 ft/lbs of TQ with Cat Bypass installed. That’s a gain of 19 HP and 23 HP, respectively, at the crank! Peak horsepower also increased from our baseline of 452 whp to 461 whp with our HJS Sport Cats and 468 whp with Cat Bypass Pipes. See our dyno graph above for more details.
