What do you mean legal requirements?

e.g. noise limits and the cats

There are no fixed noise limits IIRC. Its all down to individual policemen and MOT man's views on noise.

There is a difference between it being road worthy (pass an MOT) and legal (in the eyes of the law)

Cats will depend on the age of the car you are making it for and how friendly your MOT man is.

Emissions is based on the year of the engine, not the year of the car.

or year of car if put a different engine in it ,ive got a 2003 engine in a 1990 car with no cat!and passed the mot like that.
