That will ****** quite a few modified cars then, not just the road ones but those that are road legal but used on track. Does this mean that some cars will need to fit cans then come MOT time? But what happens after the MOT? I can see the rozzers working overtime stopping anything that seems louder than OE. Then the MOT station will get a visit. This is going to cause untold problems as insurance companies know of the mods and have a comprehensive list of things that can be changed. If this is the case, then all insurance companies will have to ban all exhaust modifications to ensure they do not get penalised as well, after all they are allowing it by covering it in the policy.
If this is the case, then we ought to buy TVRs and cause mayhem as they are loud enough OE!
Just thought, what about the rally cars that travel on public roads between stages?
does that mean homologated vehicles are immune?
