Engineered to improve exhaust flow, reduce weight and provide a more distinctive turbocharged Porsche exhaust note, the system replaces the restrictive rear section of the factory exhaust while retaining the Porsche Sport Exhaust valve functionality.
When the PSE system is switched off and the exhaust valves are closed, the system provides a quieter and more refined exhaust character suitable for normal road and motorway driving.
When PSE is activated and the valves open, exhaust gases are given a less restrictive path through the system, producing a deeper, more aggressive exhaust note with greater turbo presence, sharper sound and increased volume.
The system is manufactured from CNC mandrel-bent T304L stainless steel and incorporates Fabspeed's cast X-pipe together with Helical Limited aerospace-grade exhaust valves.
Fabspeed's dyno testing recorded gains of up to +48.7 WHP and +53.7 lb-ft of torque, with approximately 55 HP claimed at the crank, although actual results vary according to vehicle specification, fuel, atmospheric conditions and associated modifications.
The system also saves approximately 9.8 lb / 4.4 kg compared with the factory exhaust.
What This Product Does:
The cat-back exhaust carries exhaust gases from the catalytic converter outlets through the rear exhaust system and out of the vehicle.
The Fabspeed Valved Maxflo system is designed to:
- Reduce restriction in the factory rear exhaust system.
- Improve exhaust gas flow.
- Reduce exhaust backpressure.
- Improve turbocharger exhaust flow.
- Support stronger throttle response.
- Support increased horsepower and torque.
- Provide a more aggressive exhaust note when required.
- Retain a quieter exhaust mode for everyday driving.
- Maintain integration with the Porsche PSE system.
- Reduce exhaust-system weight.
- Replace the factory muffler and associated rear exhaust pipework.
- Work with either factory catalysts or compatible Fabspeed sport catalysts.
Symptoms Of Wear Or Failure:
Possible signs of deterioration in the original or aftermarket cat-back exhaust include:
- Exhaust becoming noticeably louder without the valves being commanded open.
- Ticking or blowing noises from exhaust joints.
- Exhaust gases escaping around clamps or flanges.
- Soot marks around exhaust connections.
- Metallic rattling from the rear of the vehicle.

- Exhaust tips becoming misaligned.
- Excessive movement during acceleration.
- Increased cabin drone.
- Burning smell caused by exhaust gases or hot components contacting surrounding materials.
- Valve-related noises.
- Exhaust valves failing to open or close.
- Different exhaust sound between the two sides of the vehicle.
- PSE operation no longer changing the exhaust sound correctly.
Why Replacement / Upgrading Matters:
A damaged or excessively restrictive exhaust system can affect both performance and driving enjoyment.
Replacing a worn factory system or upgrading to the Fabspeed Valved Maxflo system can help restore or improve:
- Exhaust flow.
- Turbocharged engine response.
- Exhaust sound.
- PSE valve functionality.
- Exhaust-system sealing.
- Rear exhaust weight.
- Corrosion resistance.
- Overall exhaust durability.
For performance vehicles, maintaining a structurally sound and properly sealed exhaust is particularly important because exhaust gas temperatures and flow rates can be substantial.

Designed as a replacement for the factory cat-back exhaust section, the system provides a more aggressive Porsche exhaust note while retaining the vehicle's factory-style valved exhaust functionality.
Fabspeed manufactures the system from 14–16 gauge CNC mandrel-bent T304L stainless steel and uses premium Helical Limited exhaust valves manufactured in the UK.
Fabspeed specifies the system for 992.2 Carrera 3.0L models and specifically states that it does not fit the 3.6L hybrid system used by models such as the 992.2 GTS.
What This Product Does:
The cat-back exhaust controls exhaust flow, sound attenuation and outlet routing downstream of the catalytic converters.
The Fabspeed Valved Maxflo system is designed to:
- Increase exhaust sound and character
- Provide a deeper twin-turbo flat-six exhaust note
- Retain Porsche Sport Exhaust valve operation
- Allow quieter and louder exhaust modes
- Reduce restriction through the rear exhaust section
- Increase turbocharger and exhaust sound
- Maintain factory-style fitment
- Work with the original Porsche catalytic converters
- Work with compatible Fabspeed Sport Catalytic Converters
- Retain the appropriate OEM-style exhaust tip arrangement
For a mechanically healthy vehicle, this system is primarily a sound, performance-character and exhaust-flow upgrade, rather than a wear-related maintenance replacement.
Symptoms Of Wear Or Failure:
Factory exhaust components are exposed to considerable heat, condensation, vibration and repeated thermal cycling.
Possible symptoms of deterioration include:
- Exhaust rattling
- Metallic buzzing
- Valve rattling
- Exhaust valves sticking
- Exhaust valves failing to open or close correctly
- Blowing or hissing noises
- Black soot around leaking joints
- Cracked welds
- Loose clamps
- Damaged exhaust hangers
- Corrosion
- Internal muffler rattling
- Exhaust tips sitting out of alignment
- Increased vibration
- Unwanted exhaust drone
- Exhaust gases escaping from damaged joints
A rattle should be diagnosed carefully because heat shields, mounting brackets or internal muffler components can produce similar symptoms.
Why Replacement Matters:
A damaged exhaust system can affect more than sound.
Leaks, broken mounts or failed valves can lead to:
- Excessive exhaust noise
- Unwanted rattling
- Poor exhaust alignment
- Increased stress on adjoining components
- Hot exhaust gases escaping near surrounding parts
- Loss of proper valve operation
- Damage to bumper or diffuser areas if the exhaust moves excessively
- Replacing a damaged system restores secure exhaust routing and correct operation.
Where the factory exhaust remains healthy, installing the Fabspeed system is primarily an upgrade for sound, exhaust character and freer-flowing construction.

Designed as a direct replacement for the factory Porsche exhaust outlets, the tips provide a more distinctive performance-focused appearance without requiring replacement of the complete exhaust system.
The assembly uses a lightweight titanium tip holder combined with T304 stainless-steel construction and is available in several finish options, including:
- Matte carbon fibre
- Polished stainless steel
- Brushed stainless steel
Fabspeed also offers a turn-down tip configuration intended for track and racing applications.
What This Product Does:
The exhaust tips form the final visible outlet of the exhaust system.
Their main roles are to:
- Direct exhaust gases away from the vehicle
- Provide a finished appearance at the rear of the car
- Replace the factory Porsche exhaust tips
- Allow precise positioning within the rear diffuser
- Provide a more distinctive motorsport-inspired appearance
- Fit compatible aftermarket exhaust systems that accept factory-style tips

The tips are primarily a styling and exhaust-finishing upgrade rather than a horsepower-producing performance modification.
Symptoms Of Wear Or Failure:
Exhaust tips are continuously exposed to:
- High temperatures
- Exhaust soot
- Condensation
- Road debris
- Moisture
- Vibration
Signs that the original tips or mounting hardware may require replacement include:
- Heavy scratching or scuffing
- Dents or impact damage
- Heat staining
- Corrosion
- Damaged surface finish
- Cracked carbon-fibre trim
- Loose exhaust tips
- Rattling
- Excessive movement
- Poor alignment
- Damaged or seized mounting clamps
- Tip contact with the rear diffuser
- Distorted exhaust outlets
- Burnt or deteriorated cosmetic finish
Normal heat discoloration or soot accumulation does not necessarily mean that the tips have structurally failed.
Why Replacement Matters:
Where the factory exhaust tips are only cosmetically worn, replacement is primarily an appearance upgrade.
However, loose or damaged tips can cause practical problems.
A poorly secured exhaust tip can:
- Rattle during driving
- Move out of alignment
- Contact the rear diffuser
- Damage surrounding trim
- Create an uneven rear appearance
- Eventually loosen from the exhaust outlet
Replacing damaged tips restores secure mounting, correct exhaust outlet positioning and a clean finished appearance.

Designed as a direct bolt-on replacement for the restrictive factory catalyst arrangement, the Fabspeed Sport Cat improves exhaust-gas flow while retaining catalytic exhaust treatment.
The system is engineered to increase performance, reduce weight and produce a stronger, more motorsport-inspired flat-six exhaust note without converting the vehicle to an uncatalysed exhaust setup.
Fabspeed currently publishes:
- +50 horsepower
- +40 lb-ft torque
- 12 lb weight reduction
For a mechanically healthy vehicle, this product is primarily a performance, sound and weight-reduction upgrade rather than a routine maintenance replacement.
What This Product Does:
The catalytic converter sits in the exhaust stream and treats harmful exhaust gases before they leave the vehicle.
A factory catalyst must balance:
- Emissions control
- Noise requirements
- Durability
- Packaging
- Exhaust flow
The Fabspeed Sport Cat is designed to retain catalytic exhaust treatment while allowing gases to move more freely through the exhaust system.
Its intended benefits include:
- Increased exhaust flow
- Reduced exhaust restriction
- Increased horsepower
- Increased torque
- Reduced exhaust-system weight
- More aggressive exhaust sound
- Improved performance character
- Retained catalytic exhaust treatment
- Direct bolt-on fitment
Symptoms Of Wear Or Failure:
Catalytic converters operate at extremely high temperatures and can deteriorate through age, contamination, impact or engine-related problems.
Possible symptoms include:
- Check Engine Light
- Catalyst-efficiency fault codes
- Reduced engine performance
- Poor high-RPM response
- Increased exhaust restriction
- Internal rattling
- Metallic noises from the catalyst
- Unusually high exhaust temperatures
- Sulphur-like exhaust smell
- Poor throttle response
- Exhaust flow feeling restricted
- Discolouration caused by excessive heat
- Cracks in the catalyst housing or welds
- Exhaust leakage around joints or flanges
A diagnostic inspection should be carried out before replacing a catalyst because oxygen-sensor, ignition, fuelling or engine-management faults can produce similar symptoms.
Why Replacement Matters:
A genuinely failed or restricted catalytic converter can affect:
- Engine performance
- Exhaust flow
- Exhaust temperatures
- Emissions performance
- Turbocharger operating conditions
- Engine-management operation
A severely damaged catalyst can create enough restriction to interfere with normal engine breathing.
Replacing a failed catalyst restores a clear exhaust path and proper catalytic treatment.
Where the factory catalyst is healthy, however, fitting the Fabspeed Sport Cat is primarily a performance upgrade rather than a necessary repair.
NOTE: In the United Kingdom, sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001. They are not MOT compliant and cannot be used on public roads. These components are intended solely for race and track use.
For vehicles manufactured before 1st March 2001, a non-type approved sports catalytic converter may be fitted, provided it offers comparable performance to the original and the vehicle continues to meet the applicable emissions standards for its age. The vehicle must still pass an MOT test.
If you are located outside the UK, please check your local laws and regulations to ensure compliance.

The system replaces the restrictive factory catalytic converters with German HJS 200-CPSI high-flow catalytic converters and incorporates GT2RS-inspired direct exhaust outlets with muffler adapter. This configuration creates a freer-flowing path for exhaust gases after the turbochargers while retaining catalytic exhaust treatment.
Manufactured from CNC mandrel-bent 14–16 gauge T304L stainless steel, the system is engineered as a direct bolt-on installation with no cutting or welding required.
What This Product Does:
- Replaces the factory catalytic-converter assemblies.
- Replaces the restrictive original 800-cell catalysts with HJS 200-CPSI units.
- Reduces exhaust backpressure.
- Allows exhaust gases to leave the turbochargers more efficiently.
- Helps improve turbocharger response.
- Supports increased horsepower and torque.
- Creates a more aggressive sports-car exhaust note.
- Increases audible turbocharger sound.
- Uses GT2RS-inspired direct exhaust outlets.
- Retains catalytic exhaust treatment.
- Reduces exhaust-system weight.
- Provides a modular design that can be converted back to a muffled configuration.
- Retains compatibility with the factory muffler using optional adapter pipes.
- Can also be configured with Fabspeed's Valvetronic exhaust.
- Provides a bolt-on installation without cutting or welding.
Fabspeed's HJS catalysts use a much more open internal structure than the original 800-cell units, helping the turbocharged 992 engine move exhaust gases more efficiently.
Symptoms Of Wear Or Failure:
The Fabspeed system is primarily a performance upgrade, but replacement may also be appropriate when the original catalytic converters have deteriorated.
Possible symptoms of a failing or restricted catalyst include:
- Reduced engine power.
- Sluggish acceleration.
- Increased turbo lag.
- Poor throttle response.
- Engine feeling restricted at higher RPM.
- Difficulty producing normal power under heavy load.
- Check engine warning light.
- Catalyst-efficiency fault codes.
- Rattling or metallic noises from inside a catalytic converter.
- Excessive heat from the catalyst housing.
- Strong or unusual exhaust odours.
- Increased emissions.
- Failed emissions testing.
- Exhaust leaks around joints or flanges.
- Visible damage to the catalyst housing.
- Poor fuel economy.
- Abnormally high exhaust backpressure.
A partially blocked catalyst may be relatively difficult to notice during light driving but become increasingly restrictive as exhaust-gas volume rises under acceleration.
Why Replacement Matters:
Catalytic converters sit directly downstream of the turbochargers and therefore have a significant influence on exhaust flow.
If the internal substrate becomes damaged, contaminated, melted or partially blocked, exhaust gases cannot pass through efficiently.
This increases backpressure and can result in:
- Reduced engine performance.
- Slower turbo response.
- Increased exhaust temperatures.
- Poor high-RPM performance.
- Increased load on the turbocharged exhaust system.
- Engine-management faults.
- Reduced emissions-control effectiveness.
Replacing a damaged or restrictive catalyst restores a clear exhaust path and proper catalytic function.

With over 25+ years of Porsche air and water-cooled experience, Fabspeed Motorsport USA offers a great enhancement for your stock exhaust or aftermarket exhaust on your Porsche 992 Carrera. Fabspeed was the first company to design and engineer every Porsche twin turbo exhaust enhancement. From the 1996 993TT to the 2021 twin turbo, making a sports car like the 992 Carrera / Turbo even faster and more exclusive is the domain of Fabspeed.
Using only certified high-performance HJS components imported directly from Germany, our system eliminates all risk for black market, grey market, or counterfeit HJS catalytic converters from other companies. Increase the exotic twin turbocharged Porsche sports car sound and reduce back pressure allowing for a much quicker turbocharger spooling and transient turbo response for the 992 VTG (Variable Turbine Geometry). Fabspeed sport cats replace the restrictive OEM 800 cell catalytic converters with HJS Emissions Technology catalysts guaranteeing NO CEL (Check Engine Light).
SOUND:
This system provides an aggressive sound that matches the incredible power and speed of the 992 Carrera. Expect a significant increase in volume over stock more turbo spooling sounds, while burbles and pops on deceleration are much louder and sharper.
POWER:
This is the most free-flowing exhaust design possible while still maintaining catalytic converters. When testing on our AWD Dynojet power was up across the board. Down low, the Turbo spools faster and harder, netting 23.7 WHP and 41.5 ft/lbs of TQ at 3000 RPM. Max power gains are at 5300 RPM where it gained 47.7 WHP and 47.1 ft/lbs of TQ. That's a gain of 54 HP at the crank! See our dyno graph above for more details.
