    Am I right in thinking that these exhaust systems require drivers to inform their insurance company, because they change performance?

        I couldn’t possibly say!

        But there must be records of sales of exhaust kits and records of updated insurance details. The number not matching is the number of drivers without valid insurance. It wouldn’t tell you who was who but it would give an idea of the scale.
