The Scorpion Sports Catalysts increases the gas flow while maintaining filtration rates, releasing extra performance from your engine while also being MOT friendly.
Please Note: Fitting either option will require a Stage 2 Calibration, without it the ECU will present a fault light on the dash, and it could also allow the turbo to over spool causing excessive wear and possible damage.
