This is a complete headers-to-tips 992 GT3 exhaust upgrade for ultimate weight savings and performance.
The Fabspeed RennKraft® system features a U.S. patent. This allows catted and no cat systems in a modular design.
Guaranteed to be the most powerful emissions compliant system possible. Fabspeed used all 25+ years of their Porsche exhaust experience and manufacturing techniques to engineer this incredible modular system.
Fabspeed Motorsport started with the headers. From experience designing 991 GT3 long tube headers, they knew that “long tube” headers were essential for making big power on the GT3 platform.
After dozens of dyno runs and many revisions to runner length, diameter, and Indy car merge collector design they moved on to CAD designing the catalytic converters and rear section.
With perfectly optimized headers and EMITEC HJS high-flow catalytic converters, there was no room to fit the factory muffler section, so that went out the window.
In its place went extra large 200 cell HJS cats and an investment cast, CAD designed, 70mm (2.75") X-pipe.
The HJS cats flow so much better than stock, that only 1-2 peak wheel horsepower was gained when the system was tested with no cats.
Finally, after much testing Fabspeed found that their cast X-pipe provided some significant gains from 3-6K RPM when compared to a simple crossover tube or separate 90 degree pipes.
With the patented RENNKRAFT® system, you can easily swap between catted and cat bypass using the quick release V-band clamps (patent pending).
So if you’re going to the track for racing you can swap in cat-bypass pipes for competition events.
But by using Emitec HJS European certified catalytic converters you are leaving no extra power on the table.
SOUND:
This system is awesome as it's the lightest emissions complaint systems that could be factory installed on any Porsche RSR GTLM GT3R factory race car.
It will turn your GT3 into an aggressive race-bred machine. This system is loud. It pops and bangs, and it will absolutely scream to redline.
This is at the cost of some interior drone and day-to-day comfort. We have many people worldwide that love this system and like the massive weight savings over stock.
POWER:
This is the most powerful emissions compliant 992 GT3 exhaust system on the market.
Max gains of +37 HP/ 31 WHP (whp= horsepower at the wheels) and 39 ft/lbs of TQ are seen at 4250 RPM. That’s 357HP at the crank! Gains of over 20 WHP are carried all the way from 6000 RPM up to redline. Usuable power ALL across the RPM band from Fabspeed Motorsport applying over 30 years of Air-cooled and water-cooled experience. You’re going to feel the power that this system adds to your GT3!
