These modular headers are the perfect solution for any street driven 992 GT3/ GT3RS. Fabspeed's 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 QUICKTRACK™ cat bypass “straight pipes” for track use. Rennkraft, translated from German is “race power”. These unique headers offer true street and racetrack functionality in an innovative precision engineered package.

Sound:

Many say sound is a subjective thing, but we like to think we’ve made the 992 GT3 sound objectively better with these high flowing headers. Equipped with our 200 cell cats, you will get a louder 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, even with the cat bypass option installed.

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 18 HP and 22 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.
