Your standard exhaust will require cutting to be removed, this should be carried out by a competent person.

This KMS system will enhance exhaust gas flow, reduce restriction, improve sound, performance and driveability and allow the car to gain more POWER!

The decat/sportscat may bring on your MIL (Malfunction Indicator Lamp) unless you have stage 2 software.

Please Note: An exhaust system without a catalytic converter will NOT pass a UK emission test/road side check and therefore it is not intended for road use.

Due to the popularity of our exhaust systems, stock may fluctuate - please note we do endeavour to build a system within 10 working days if not available.

Black Trim option may be up to 3 weeks depending on stock levels
