It’s the inverse - the car is quiet for just one day, its MOT day. The owner will put the standard exhaust on for the MOT, then put the loud one back on once they have the MOT pass certificate in hand. Same thing with numberplates with odd spacing to make words. The owner will put a standard plate on for the MOT then swap it for their illegally spaced one once the MOT is done.
Is a car noisy for just one day?

Yes, that’s what my mechanic told me.
