Making something illegal and actually enforcing it are two very different things though. Most countries in the world have a cap on noise levels your vehicle can make, most don't do much to enforce it outside of yearly checkups.

In most parts of Switzerland there is no yearly checkup, but every 2 years or whenever you get the invite (waited 3 years once).

However police is actively monitoring noise levels in some places, picking out the cars and remove them from the streets. Just last weekend my closest city checked 15 and removed about half of these cars in one evening.
