Because this will remove a catalytic converter it is not road legal in the UK. It is also likely to bring on an engine management light, there are 2 solutions to remove this, 1/ have the car remapped 2/ fit engine light cheater to the lambda sensors. Option 1 is the prefered method as it will also allow the engine to fully take advantage of the improved flow and maximise the power. If you choose option 2 then ask for the link to the cheaters.
