As far as I aware (please correct me if I am wrong) there is no noise limit quoted for MOT test and it is not measured. I have heard of an Astra being failed because the exhaust was significantly noisier than other Astra. It would be difficult to do this with a kit car as it's unlikely testing stations will be able to use that criteria. Obviously, new cars have to go through IVA which does have a noise limit and test.
