These headers are typically built per order. Our "In Stock" status does not include build time. Delivery time is usually 1-2 weeks.
These Fabspeed Motorsport modular headers are the perfect solution for any street driven 992 GT3/RS. The US Patented RENNKRAFT® modular design features a quick release V-band connector that allows you to easily swap between our EMITEC HJS 200 cell catalytic converters and QUICKTRACK™ link pipes for track use.
Rennkraft®, translated from German is “Race Power”. These unique headers offer true street and race track functionality in an innovative package.
Fabspeed was the first company to 3D laser scan, design, patent and Dyno develop these premium headers. There is no better header available for your 992 GT3
SOUND:
Fabspeed Motorsport USA, utilizing 29+ years of experience has made the 992 GT3 sound incredible with these high flowing headers.
Equipped with HJS German 200 cell cats, you will get a more aggressive CUP car style exhaust note with a more raw flat 6 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 race track only monster.
At part throttle the volume isn't overbearing, but the sound is very aggressive. With the stock muffler in place, there is no drone what-so-ever with maximum clean and green emissions power.
POWER:
After extensive dyno development Fabspeed found the optimal header length and diameter. With no tune, compared to a stock car they gained 19HP (16 whp) and 20 lb/ft of torque with the sport cats and 23HP (19 whp) and 26 lb/ft of torque with cat bypass pipes installed.
That's a gain of 19 and 23 horsepower respectively, at the crank! Peak horsepower also increased from our baseline of 452 whp to 461 whp with HJS sport cats and 468 whp with cat bypass pipes.
As you can easily see EMITEC HJS tri-metallic catalytic converters deliver virtually all the clean and green power you want. See the dyno graph above for more details.
FEATURES:
- Fits all Porsche 992 GT3 and GT3 RS 2022+ models. (This system does delete the GPF on EU cars, and will cause a check engine light for a monitored GPF system unless a simulator or tune is used)
- Impressive dyno gains of 20 horsepower and 25 lb/ft of torque at the crank or 16 wheel horsepower and 20 lb/ft of torque with the sport cats and 19 whp and 26 ft/lbs of torque with link comp pipes installed
- This patented system is the first dual use street or track system.
- Save 6 lbs (2.7 kg) compared to the factory headers
- Modular design that uses a V-band clamp so you can quickly swap between cats and comp link pipes for racing.
- Modular patented design also allows HJS catalytic converter replacement as needed. Simply remove old catalytic converter and install a new replacement catalytic converter if needed.
- The cat bypass pipes are not intended for street usage and to defeat emissions.
- Constructed from CNC mandrel-bent T304L stainless steel, lost wax precision investment cast inlet flanges and CAD designed CNC flanges.
- Switching to cat-bypass for track events prevents catalytic converter degradation during racing abuse
- With the RENNKRAFT® system, you can quickly install the QUICKTRACK™ cat bypass pipes for racing events
- The RENNKRAFT® system has been awarded a US Patent and is the only system of its kind in the world
- F1 style high velocity, triangular merge collectors with merge spike for maximum scavenging.
