Product details
Fabspeed’s Primary Sport Catalytic Converters replace the original primary converter assemblies on the 2008–2010 Porsche 957 Cayenne Turbo and Turbo S. Their HJS catalyst cores distinguish them from the empty secondary bypass pipes used elsewhere in the exhaust. Fabspeed Motorsport engineers sports-car exhaust, intake and ECU-tuning systems in Fort Washington, Pennsylvania. Its development work includes dynamometer testing and evaluation on the road and racetrack.

Fitment & Compatibility
| Years | Make | Model / chassis | Version / application | Fitment notes |
|---|---|---|---|---|
| 2008–2010 | Porsche | Cayenne (957) | Turbo / Turbo S | Match the primary-catalyst connections and sensor layout. Manufacturer restricts this product to closed-course use; catalyst presence does not establish road approval. |
Match the 957 Turbo / Turbo S exhaust and sensor layout. Fabspeed’s specific product restriction states these high-flow catalysts are for closed-course use and are not CARB or EPA certified. A catalyst core or lack of a fault light is not evidence of approval for public-road use.
