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

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.
