Description
The Fabspeed Motorsport Valvetronic Nordschleife Cat-Back Exhaust System gives the 992 GT3 a truly exotic sports car sound, all while retaining the functionality of PSE (Porsche Sport Exhaust). Our design process started with 3D laser scanning the entire OEM exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then CAD designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and ACTUAL dyno testing we decided to use our signature cast 70mm 2.75″ X-Pipe to tie the two cylinder banks together for exhaust scavenging and to defeat resonance. The exhaust valves are made by Helical Limited in the United Kingdom. These ISO 9001 certified valves are the same ones Ferrari, McLaren and Porsche use on their GT cars. The piping is mandrel bent from T304 Stainless steel, and you have five different tip options to choose from. This systems is GUARANTEED to make the very best sports car sound and MORE power than any other system in the WORLD! Ultimate quality bullet-proof exhaust valves and linking both exhaust banks of the FLAT 6 required real true engineering versus simply slapping together two 90 degree straight pipes like many other companies or utilizing 3″ tubing 100% guaranteed to make less horsepower and torque versus Fabspeed.
SOUND:
With PSE off our Valvetronic exhaust gives a nice subtle increase in volume. With PSE on it turns the 4.0L’s exhaust note into a truly exotic sound with a significant increase in volume. The exhaust note changes from the smooth purr of the OEM exhaust to the aggressive race-bred snarl of a 911 CUP car. The invest cast X pipe CAD designed is crucial to deliver high pitched GT3 sports car sound. Serious after we designed and BUILT 4 different exhaust systems we ONLY deliver the very best system in terms of sports car sound and maximum power. Typically in this industry competitors “wack something together and never ever test it, use CHEAP as Dirt Chinese exhaust valves 100% guaranteed to fail” and go to market with Maximum hype. Fabspeed with over 25+ years of air-cooled and water-cooled experience never ever takes short cuts.
POWER:
This system improves on Porsche’s design by increasing pipe diameter from 2.5 in to 2.75in 70mm and using our signature cast X-pipe instead of the factory H-Pipe. On our DynoJet we saw +17.5 crank HP or +14 whp (whp= horsepower at the wheels) at 4200 RPM and a healthy dose of torque down low at 4200 RPM gaining 17 ft/lbs of tq. Significant power gains that you can feel by the seat of your pants and also major rear weight savings. FYI, for your information a 3″ X pipe LOST 15FTLB torque and -10HP versus 70mm. Larger is 100% the wrong way to go. Caveat Emptor- buyer beware.
FEATURES:
- Fits all Porsche 992 GT3 and 992 GT3 RS 2022+ Models Worldwide
- Significant Dyno gains across the RPM band. +17 ft/lbs tq @ 4200RPM and 17.5HP crank +14 whp @ 4200RPM
- Dyno developed incrementally to give you the MAXIMUM Horsepower and superlative GT3 Cup style sports car sound.
- Weight savings of 5lbs / 2.3KGs vs the factory exhaust
- Completely retains PSE valved exhaust functionality.
- Uses aerospace quality Helical Limited exhaust valves imported from the U.K. NO cheap guaranteed to fail valves from Asia!
- Helical exhaust valves MUST be mandatory on any and all Porsche exhaust systems. If you are BUYING ask the other GUYS if these use Helical limited U.K. exhaust valves? If they dont or start saying their valves are JUST as GOOD RUN FAST!
- Helical exhaust valves are aerospace grade valves that Porsche , Ferrari, McLaren , Pagani, Koeniggseeg , Gordon Murray use exclusively- no cheap as dirt 100% guaranteed to fail $50 Chinese valves.
