Fabspeed Valvetronic Nordschleife cat-back exhaust system.



The Fabspeed 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 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 designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and dyno testing we decided to use our signature cast 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.

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. (If you need to cut down on how loud your exhaust is because of race track rules, we sell turn down tips which cut 3-6db of exhaust SPL.)

POWER:

This system improves on Porsche's design by increasing pipe diameter from 2.5 in to 2.75 in and using our signature cast X-pipe instead of the factory H-Pipe. On our DynoJet we saw +14 whp at 4200 RPM and a healthy dose of torque down low at 4200 RPM gaining 17 ft/lbs of tq. That's 16 HP gain at the crank.

FEATURES:

• Fits all Porsche 992 GT3 2022+ Models worldwide w/o monitored GPF (Solution for GPF monitored cars will be released shortly)
• Significant Dyno gains across the RPM band. +17 ft/lbs tq @ 4200RPM and +14 whp @ 4200RPM
• 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.
• Incorporates our signature cast X-pipe for superior flow and exhaust scavenging
• This cat-back system is emissions legal in all 50 states and the rest of the world (ROW)
• Constructed from high-quality 14-16ga CNC mandrel-bent T304L stainless steel for optimum flow and maximum durability
• Laser scanned and CAD designed for perfect OEM fitment using an Ametek Handyscan 700
• No Check Engine Light guaranteed
• Simple DIY bolt-on installation, no cutting or welding required
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

Fabspeed RENNKRAFT™ Modular GTLM exhaust package.



This is a complete headers to tips exhaust solution for the 992 GT3. Designed to be the most powerful emissions compliant exhaust system possible. We used all 25+ years of Porsche exhaust design experience and our finest manufacturing techniques to engineer this incredible modular system. We started with the headers. From our experience designing our 991/991.2 Long Tube Headers, we 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 collector design we moved on to the catalytic converters and rear section. With perfectly optimized headers and cats, there was no room to fit the factory muffler section, so that went out the window. In its place we implemented extra large 200 cell HJS cats and our signature cast X-pipe. These cats flow so much better than stock, that we only gained 1-2 peak WHP when we tested the system with no cats. You can see the dyno graph for yourself above. Finally, after much testing we found that our cast X-pipe provided some significant gains from 3-6K RPM when compared to a simple crossover tube. With the 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 you can swap in cat-bypass pipes.

SOUND:

This system isn't for the faint of heart, it'll turn your GT3 into a snarling race-bred monster. This system is LOUD, it pops and gurgles, and it will absolutely scream at redline. This is at the cost of some interior drone and day-to-day livability.

POWER:

This is the way; the most powerful emissions compliant 992 GT3 exhaust system on the market. Max gains of 31 WHP and 39 ft/lbs of TQ are seen at 4250 RPM. That's 35 HP at the crank! Gains of over 20 WHP are carried all the way from 6000 RPM up to redline. You're going to feel the power that this system adds to your GT3!

FEATURES:

• Fits all Porsche 992 GT3 Vehicles (2022+) (This system does delete the GPF, and will cause a check engine light for a monitored GPF system unless a simulator or tune is used)
• Adds 31 WHP and 39 ft/lbs of TQ at 4250 RPM (35 HP at the crank)
vSaves a massive 18lbs / 8.2 KGs versus the stock factory Porsche OEM system
• Equal length headers with Burns Stainless Formula 1/ Indy car style high velocity merge collectors
• Springs used for collector retention to accommodate for expansion and increase durability
• Constructed from T321 stainless steel Mil Spec tubing- ASME specifications
• CNC mandrel bent tubing featuring 2.75in / 70mm tubing
• Investment cast stainless steel flanges for maximum flow and strength
• Modular design that uses a V-band clamp so one can quickly swap between cats and cat bypass
• Switching to cat-bypass for track events prevents catalytic converter degradation during all out competition racing abuse

Why We Choose HJS Catalytic Converters:

HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light. If you'd like to learn more, watch our video about HJS catalytic converters.

Fabspeed 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 made HJS 200 cell cats and QUICKTRACK™ cat bypass "straight 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:

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 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.

FEATURES:

• Fits all Porsche 992 GT3 2022+ Models worldwide (This system does delete the GPF, and will cause a check engine light for a monitored GPF system unless a simulator or tune is used)
