Ask for a look underneath first. Many leaks can be fixed by replacing one section or a gasket instead of the whole system. If your catalytic converter is replaced, ask whether the part is legal in your state — California and some other states require CARB-approved converters.

Good to know

How much does a muffler replacement cost?

Replacing a muffler typically costs about $100–300 at an independent shop; a full exhaust system or a catalytic converter costs considerably more, depending on the vehicle.

Is it legal to drive with a loud exhaust?

Most states have laws against excessive exhaust noise and against removing emissions equipment, so a hole in the exhaust can lead to a ticket or a failed inspection.
