Engineered by Fabspeed Motorsport, these high-performance catalytic converters replace the restrictive factory catalytic converter assemblies with advanced German-manufactured HJS 200-cell high-flow sports catalysts.
Their performance-focused design reduces exhaust backpressure while retaining catalytic exhaust treatment, allowing exhaust gases to pass more efficiently through the system.
Manufactured from premium T304L stainless steel, the system features precision mandrel-bent pipework designed for durability, efficient exhaust gas movement and reliable operation under demanding temperatures.
Fabspeed reports that the HJS sports catalytic converters provide exhaust flow equivalent to approximately 93–95% of a straight pipe, offering a substantial reduction in restriction compared with conventional factory catalytic converters.
The system also enhances the characteristic sound of Porsche's 4.0L twin-turbocharged V8 engine, producing a deeper and more aggressive exhaust note, with more pronounced pops, bangs and crackles during spirited driving.
Fabspeed reports maximum performance gains of approximately 22 wheel horsepower and 21 lb-ft of torque, alongside a weight reduction of approximately 6 lbs (2.7 kg) compared with the original catalytic converter assemblies.
Designed for direct bolt-on installation without cutting or welding, the Fabspeed Sport Catalytic Converters provide a performance-focused upgrade for Porsche Cayenne owners seeking enhanced sound, improved responsiveness and premium exhaust construction.
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 combustion before the exhaust gases leave the tailpipes.
As exhaust gases pass through the catalytic converter, the catalyst promotes chemical reactions that convert 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 exhaust flow path compared with the original equipment.
Their main functions include:
- Improving exhaust gas flow: High-flow HJS 200-cell catalysts allow exhaust gases to pass more freely through the system.
- Reducing exhaust backpressure: A less restrictive catalyst design helps minimise pressure downstream of the turbochargers.
- Supporting turbocharger efficiency: Improved exhaust discharge can contribute to more responsive turbocharger operation.
- Increasing horsepower: Reduced exhaust restriction can support additional engine power, with Fabspeed reporting maximum gains of 22 wheel horsepower.
- Improving torque delivery: Enhanced exhaust flow can contribute to stronger acceleration and improved torque.
- Enhancing exhaust sound: Produces a deeper and more pronounced exhaust note, highlighting the character of Porsche's twin-turbocharged V8 engine.
- Maintaining catalytic exhaust treatment: Retains functioning catalytic converter cores rather than using unrestricted bypass pipes.
- Supporting emissions control: Helps reduce harmful exhaust pollutants when operating correctly.
- Reducing exhaust system weight: Saves approximately 6 lbs (2.7 kg) compared with the factory catalytic converters.
- Supporting high-temperature durability: Stainless steel construction is designed to withstand demanding exhaust operating conditions.
Symptoms Of Wear Or Failure:
The original Porsche Cayenne catalytic converters operate under demanding conditions, including high exhaust temperatures, repeated thermal cycling, vibration and exposure to exhaust contaminants.
Over time, catalytic converters may deteriorate due to overheating, contamination, mechanical 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 and reduce available engine power.
- Sluggish acceleration: Excessive exhaust restriction can affect turbocharger response and engine performance.
- Engine management warning light: Reduced catalytic converter efficiency may trigger the check engine light.
- Catalyst efficiency fault codes: Diagnostic codes such as P0420 or P0430 may indicate below-threshold catalyst efficiency, although other faults can produce similar codes.
- Metallic rattling: A damaged or broken internal catalytic converter substrate may produce rattling noises from the exhaust system.
- Excessive exhaust temperatures: A severely restricted catalytic converter may contribute to abnormal heat build-up.
- Unusual exhaust odours: Poor catalytic converter performance may increase unpleasant exhaust smells.
- Increased fuel consumption: Severe exhaust restriction or associated engine management problems may affect fuel efficiency.
- Failed emissions inspection: A deteriorated catalytic converter may no longer reduce exhaust pollutants sufficiently.
- Visible exhaust damage: Cracked converter housings, damaged welds or leaking connections may compromise the exhaust system.
- Exhaust blowing or hissing: Damaged joints or pipework can allow exhaust gases to escape before reaching the tailpipes.
- Abnormal turbocharger response: Significant downstream exhaust restriction may interfere with efficient turbocharger operation.
Why Replacement Matters:
Replacing the original catalytic converters with Fabspeed Sport Catalytic Converters provides an opportunity to improve the Porsche Cayenne's exhaust efficiency, enhance engine sound and increase overall driving enjoyment.
While conventional replacement catalytic converters restore the original emissions system, Fabspeed's high-flow HJS design is engineered to reduce exhaust restrictions while retaining catalytic conversion functionality.
The 200-cell sports catalysts provide a less restrictive exhaust pathway, allowing the twin-turbocharged engine to discharge exhaust gases more efficiently.
Upgrading to Fabspeed Sport Catalytic Converters offers several benefits:
- Increased engine power: Fabspeed reports maximum gains of approximately 22 wheel horsepower.
- Improved torque: Manufacturer-reported gains of up to 21 lb-ft support stronger acceleration and improved performance potential.

- Premium HJS catalytic technology: German-manufactured 200-cell catalysts provide high-flow performance and catalytic exhaust treatment.
- Durable stainless steel construction: T304L stainless steel offers resistance to heat, corrosion and environmental exposure.
- Lightweight design: Saves approximately 6 lbs (2.7 kg) compared with the original catalytic converter assemblies.
- Vehicle-specific engineering: Designed for compatible Porsche Cayenne E3 twin-turbocharged V8 models.
- Direct bolt-on installation: Replaces the original catalytic converters without cutting or welding.
- Enhanced driving enjoyment: Combines improved exhaust sound with increased performance potential.
