Fabspeed Sport Cat.

The Fabspeed Porsche 992.2 Carrera GTS Sport Cat is a high-flow catalytic-converter upgrade developed specifically for the 2025+ Porsche 992.2 Carrera GTS T-Hybrid.

Fits:

• Porsche 992.2 Carrera 2 GTS 3.6L 2024>>
• Porsche 992.2 Carrera 4 GTS 3.6L 2024>>  

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.
