What happens when the catalytic converter is stolen from a car?

[GabrielleAnn]

If you notice a significantly louder exhaust sound when starting the engine, it is likely that the catalytic converter has been stolen, as the vehicle's noise cannot be eliminated after the catalytic converter is removed. You can also check if the smell of the exhaust has become stronger. If the catalytic converter is malfunctioning or stolen, pollutants in the exhaust cannot be removed, leading to a noticeably stronger odor. More information about catalytic converters is as follows: 1. Function: The catalytic converter uses precious metals inside to catalyze pollutants in the exhaust. 2. Theft: If you discover that the catalytic converter has been stolen, you should promptly notify the police, as thieves often target multiple vehicles in the area, meaning more than one person may be affected. After the police file a report, you should go to a 4S shop to have the catalytic converter reinstalled. Otherwise, the vehicle's engine warning light will remain on and cannot be turned off. Most importantly, without a catalytic converter, the vehicle will not pass the annual inspection.
