How to Know If the Catalytic Converter Has Been Stolen?

[Mia]

After the catalytic converter is stolen, the vehicle's exhaust sound will become very loud, and a noise similar to that of an old-fashioned tractor can be heard when starting the engine. The catalytic converter effectively catalyzes harmful substances in the exhaust. After being stolen, the smell of the vehicle's exhaust will become stronger. You can drive the car onto a lift and then check whether the catalytic converter is still in place.
