Composite gaskets included.
+8HP and significantly more torque.
Saves 11lbs/5kg over stock catalytic converters.
This new modular system includes a 200 cell German imported sport catalytic converter and cat bypass option in one interchangeable system.
993 Sport Catalytic Converter X-Pipe is different for certain years. 1994-1996 1/2 993's and all 993 SUPERCUP cars (1994 to 1997 993CUP) have Bischoff oval 3 bolt flanges. 1996+1998 993's are all Gillett round 3 bolt flanges. YOU MUST CORRECTLY specify flange type when Ordering.
When in doubt go check especially the late 1995 and early 1996 cars as this was a "cross-over year" and flange style changed during the year.
T304 Stainless steel C.N.C mandrel bent with polished show car mirror shine.
Simple and easy Bolt-on and bolt-off when you need to!.
Best PROVEN performance value on the market.
Might require blanking plug (90012300920) and washer (90021901500). Available separately.
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.
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 Fabspeed Sport Catalytic Converters With Muffler Adapter Only are a high-performance exhaust upgrade for the Porsche 911 992 Carrera, designed to reduce exhaust restriction, improve turbo response and deliver a significantly more sporting exhaust character.
Fits:
- Porsche 992.1 Carrera 2 3.0L 2021-24
- Porsche 992.1 Carrera 4 3.0L 2021-24
- Porsche 992.1 Carrera 2 Cabriolet 3.0L 2021-24

The system replaces the restrictive factory catalytic converters with German HJS 200-CPSI high-flow catalytic converters. This configuration creates a freer-flowing path for exhaust gases after the turbochargers while retaining catalytic exhaust treatment.
Fabspeed's modular design also provides flexibility. The adapter pipes, allow the sport catalysts to be used with the factory rear muffler or Fabspeed Valvetronic exhaust if a quieter configuration is preferred.
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.
- 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.
