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.

Fabspeed Cat-Back Valved Maxflo Exhaust System.

The Fabspeed Cat-Back Valved Maxflo Exhaust System is a premium performance exhaust upgrade developed for the 2025+ Porsche 992.2 Carrera with the 3.0-litre twin-turbo flat-six engine.

Fits:

• Porsche 992.2 Carrera 2 3.0L 2024>>
• Porsche 992.2 Carrera 2S 3.0L 2024>>  

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 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.

• 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.

In addition to improved exhaust flow, the sports catalytic converters produce a more pronounced exhaust note, allowing the character of the Porsche flat-six engine to become more noticeable during acceleration and spirited driving.

Designed as a direct bolt-on replacement, the Fabspeed Sport Catalytic Converters require no cutting or welding and can be removed to restore the original exhaust configuration if required.

Ideal for Porsche enthusiasts seeking improved engine performance, enhanced exhaust sound and premium construction, these Fabspeed Sport Catalytic Converters provide a high-quality alternative to the factory catalytic converter assemblies.

What This Product Does:
Catalytic converters are essential components of a vehicle's exhaust emissions control system. Their primary function is to reduce harmful pollutants produced during engine combustion before the exhaust gases leave the tailpipes.

As exhaust gases pass through the catalytic converter, the catalyst promotes chemical reactions that convert harmful pollutants, including carbon monoxide, unburned hydrocarbons and nitrogen oxides, into less harmful substances.

The Fabspeed Sport Catalytic Converters perform this emissions-treatment function while providing a less restrictive path for exhaust gases compared with the original factory converters.

Their main functions include:

• Reducing exhaust emissions: Catalytic converter cores help convert harmful exhaust pollutants into less harmful substances.
• Improving exhaust gas flow: High-flow 200-cell HJS catalysts reduce restriction compared with the factory 700-cell catalytic converters.
• Reducing exhaust backpressure: Less restrictive pipework helps exhaust gases move more efficiently through the system.
• Supporting turbocharger efficiency: Improved exhaust flow downstream of the turbochargers can support efficient turbocharger operation.
• Increasing horsepower: Reduced exhaust restriction can contribute to additional engine power, with Fabspeed advertising gains of up to 53 HP.
• Improving torque delivery: Enhanced exhaust flow can support stronger acceleration and increased torque.
• Enhancing throttle response: More efficient exhaust gas discharge helps support responsive engine operation.
• Improving exhaust sound: Produces a deeper, more pronounced sports exhaust note compared with the factory catalytic converters.
• Maintaining catalytic exhaust treatment: Retains functioning catalytic converter cores rather than replacing them with unrestricted bypass pipes.
• Supporting high-temperature durability: Premium stainless steel construction and heat shielding help withstand demanding exhaust operating conditions.

Symptoms Of Wear Or Failure:
Factory catalytic converters operate under extreme conditions, including high exhaust temperatures, repeated thermal cycling, vibration and exposure to exhaust contaminants.

Although designed for long service life, catalytic converters may eventually deteriorate due to overheating, contamination, physical damage or internal substrate failure.

Common symptoms of worn or failing catalytic converters include:

• Reduced engine performance: A blocked or restricted catalytic converter may increase exhaust backpressure, reducing engine power and responsiveness.
• Sluggish acceleration: Excessive exhaust restriction can make the engine feel less responsive, particularly under heavy acceleration.
• Engine management warning light: Reduced catalytic converter efficiency may trigger the check engine light and associated diagnostic fault codes.
• Catalyst efficiency fault codes: Diagnostic codes such as P0420 or P0430 may indicate below-threshold catalytic converter efficiency, although other faults can cause these codes.
• Rattling noises: A damaged or broken internal catalytic converter substrate may produce metallic rattling sounds from the exhaust system.
• Excessive exhaust heat: A severely restricted converter can cause abnormal temperature build-up within the exhaust system.
• Unusual exhaust odours: Poor catalytic converter performance may contribute to noticeable exhaust smells or increased pollutant emissions.
• Increased fuel consumption: Severe exhaust restriction or associated engine management faults may affect fuel efficiency.
• Failed emissions inspection: A deteriorated catalytic converter may no longer provide sufficient exhaust pollutant conversion.
• Visible exhaust damage: Cracked converter housings, damaged welds or corroded connections may allow exhaust gas leakage.
• Abnormal turbocharger response: Significant exhaust restriction may interfere with efficient exhaust gas discharge from the turbochargers.
• Overheating or substrate damage: Engine misfires, incorrect fuel mixtures or excessive exhaust temperatures can damage the internal catalyst material.

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.
