Please note that sports cats are not legally permitted to be installed on a vehicle manufactured after 1st March 2001 unless they meet the ECE 103R approval standards. Fitting a De Cat / Cat Bypass or GPF delete/bypass onto a vehicle intended for use on UK roads will result in the vehicle failing its MOT emissions test, making it unroadworthy and illegal to use on the road.
In general, replacing your stock cat will also require a remap, as the ECU will be getting different readings from the Lambda sensors in the exhaust, which may read as an error. An upgraded cat is often an essential component of high-performance upgrade packages.
