PLEASE BE AWARE: Sports cats can NOT legally be installed on a vehicle for use on a public road that was manufactured after 1st March 2001 unless type ECE 103R approved - this can be identified in either the product description and/or in the Technical Information section listed. If you have any doubt on this approval, please contact us immediately for confirmation. Fitting a De-Cat/Cat Bypass, DPF delete/bypass or GPF delete/bypass to a vehicle that is to be used on UK roads will cause the vehicle to fail the MOT emissions test, therefore rendering it unroadworthy and illegal to be used on the road. Therefore, any such products are strictly sold as off-road or motorsport use only and NOT for road use. The vehicle should be transported from place to place via a trailer, flatbed or other recovery means.
