The 918 Spyder is one of the all time greats to come out of the Porsche factory but there's still room for improvement in a few areas.

We recently turned our attention to this incredible machine and through the use of Inconel 625 and high end motorsport heat shielding technology have been able to extract a little more power plus an all new incredible tone from the exhaust which brings a whole new character to this car, especially with the roof removed.

Direct Replacement / Modular Fitment

The JCR Inconel Race Cats are a full direct replacement product for the OEM 918 Spyder cat pipes. No fabrication required and no additional parts. Simply remove the factory cat sections and replace with the JCR Inconel Race Cats and enjoy weight savings, power gains and trouble free running with no requirement for any ECU tuning and no chance of CEL.

Heat Management

Our 918 Spyder Race Cats feature the highest quality thermal protection as standard. The heat shielding we have selected is used in the very highest levels of Motorsport to control temperatures whilst protecting and dramatically reducing the effects of radiant heat into the surrounding areas.

Race Cats

Our Inconel Race Cats utilise 200cel HJS Race Cats. This means you benefit from the HP and TQ increase along with a subtle bump in overall volume vs the factory cat pipes whilst keeping the car emissions legal. This makes for a great option for street cars which require functioning cats to be placed in the exhaust system.

Light Weight

Due to the 100% Inconel construction the JCR Inconel Race Cats removes an impressive 6.77kg from the factory exhaust set up. This truly is a win win modification.

Performance Increase

Our Inconel Race Cats are guaranteed to not only deliver a fantastic sound but also improve HP & TQ with varying results dependant on the combination of parts installed without risk of check engine lights
