A Quick Look at Fabspeed
Fabspeed information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.
Choosing the Right Fit for Your Porsche
Where Fabspeed is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.
- Typical reasons people replace these parts include upgrading tired or corroded factory exhaust components, tailoring sound and response for fast-road or track use, and supporting wider tuning packages.
- Common symptoms that lead owners to inspect or change related parts include exhaust leaks, rattles, drone, heat-related fatigue, and loss of performance that may also be linked to boost or vacuum issues.
- After installation, it is sensible to refresh mounts and hardware where worn, and to carry out a careful check for leaks once everything has heat-cycled.
- Consider whether supporting ECU mapping or health checks are appropriate for your Porsche, depending on how extensive your hardware changes are.
Browse by Category
If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.
Engine Tuning — Engine tuning parts and upgrades for Porsche are used to improve drivability, throttle response and power, or to support changes such as intake, exhaust, or forced induction. They are typically chosen once the engine is in good health, as tuning cannot compensate for underlying mechanical faults.
- Before any significant tuning work, check overall engine condition, including compression or leak-down where appropriate, fuel system health, sensor data, and that there are no boost or vacuum leaks.
- Avoid using calibration changes to hide rough running or misfires, as the mechanical root cause still needs to be addressed.
Air Filters — Air filters for Porsche protect the engine from dirt while maintaining the airflow that correct fuelling and performance depend on. Owners often replace or upgrade filters to restore airflow, support tuning work, or improve serviceability while keeping good filtration.
- Service intervals depend on use: dusty environments or frequent track days may justify more frequent inspection and cleaning or replacement.
- If using oiled performance filters, follow the manufacturer’s oiling instructions carefully to avoid contaminating sensitive airflow sensors.
Air Induction Kits — Induction kits for Porsche replace or re-route parts of the intake system to change airflow, response and sound. They are usually part of a wider tuning package and are selected to balance intake temperatures, flow and sensor stability.
- When fitting an induction kit, ensure joints and connections are well sealed to prevent unmetered air entering the engine or causing drivability issues.
- Positioning and heat management are important: shielding from hot engine-bay air helps keep intake temperatures, and therefore performance, more consistent.
Exhausts — Exhaust upgrades for Porsche are commonly chosen to replace corroded or leaking factory systems, refine the car’s sound, reduce weight or improve gas flow as part of a tuning package. The right choice depends on how the car is used and the balance you want between sound, comfort and responsiveness.
- When planning an exhaust change, consider the complete system, including catalytic converters, to keep within your local emissions and noise requirements.
- Replacing aged gaskets, clamps, mounts and rusted fixings at the same time as the exhaust usually improves fitment and reduces the chance of future leaks or rattles.
All Silencers / Mufflers — This category covers a range of Porsche silencer and muffler layouts, from standard-style replacements to sport and valved options. Selection is usually guided by corrosion or damage to existing parts, unwanted noise or drone, or a desire to change the exhaust character while staying within comfort and usage needs.
- To narrow down the correct layout, compare inlet and outlet positions, hanger locations and pipe diameters on your current system against the product details.
- When choosing between standard, sport or switchable systems, think about typical journeys and cabin noise tolerance so you end up with a sound level that suits day-to-day use.

Porsche Boxster Cayman owners have requested a conversion kit that allows the installation of a Porsche OEM 991 GT3 center muffler onto their cars. Fabspeed Motorsport listened and designed in CAD and built inhouse a lightweight installation kit that allows any 6 speed Porsche 981 GT4 or Spyder owner to install an OEM GT3 center muffler (A PDK version will also be available once we are able to test fitment). This kit also allows the installation of a Fabspeed 991 GT3 Center Muffler Bypass Pipe or 991 GT3 Center Mini Maxflo Performance Exhaust onto your 981 GT4/Spyder.
The system consists of 2.5" 63.5mm CNC mandrel bent one piece Left and Right side over axle pipes and clamps. Then a set of valved side muffler inlet Y-pipes that retain the factory PSE valved exhaust functionality. The valves are OEM Porsche GT3 HELICAL vacuum-actuated exhaust valves that are imported from the U.K. We use our FLOW Waterjet to cut a CAD designed, lightweight, stainless steel mounting bracket to hold the muffler; hardware for installation is included. This and the Factory Porsche muffler band straps hold everything in place. For tips, you can use the factory 991 GT3 tips or you can order our custom exhaust tip mount with any choice of our signature tips.
SOUND: Enjoy the characteristic sound of a factory Porsche engineered exhaust but with a nice increase in volume! With PSE off (valves closed), the exhaust is still tame and livable in the cabin. However, with PSE on (valves open) hear that flat 6 howl up to redline! The larger over axle pipes that are included also contribute to the overall louder tone.
POWER: The 991 GT3 muffler was designed by Porsche to support 475 HP, because of this it flows a lot better than the 981 GT4 muffler that was only designed for 385 HP. We expect this increase in flow, helped by our larger over axle pipes and muffler inlets, to give a nice HP increase.
FEATURES:
- Fits all 6 speed manual Porsche 981 Cayman GT4 / 981 Boxster Spyder vehicles (2015-2016). A PDK version will also be available once we are able to test fitment
- Choose between your choice of Premium Fabspeed Exhaust Tips or use OEM 991 GT3 Tips.
- CNC Mandrel bent 2.5" 63.5 precision over axle pipes to valvetronic inlet pipes
- Helical Aerospace United Kingdom exhaust valves- same OEM quality valves used on Porsche GT3, GT3RS. Made with Silica carbide.
- Constructed from 14-16ga T304L stainless steel tubing for maximum power and durability
- Direct bolt-on installation; no cutting or welding required
- All Fabspeed performance products are backed by the Fabspeed Lifetime Limited Warranty.
NOTE: OEM GT3 center muffler is NOT included
Please note: This is a special-order item manufactured to order. In some cases, please allow 4 – 5 weeks for the delivery. Special order items cannot be cancelled from this supplier once your order has been placed.

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 / GT3 RS 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

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.

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.

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 / GT3 RS 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
