Understanding Catalytic Converters: How to Guard Against Theft

There are times when catalytic converters become a common topic in the news, and unfortunately, it’s usually due to theft. These thefts can lead to expensive repair bills and leave vehicle owners feeling frustrated and vulnerable. While the rate of theft has decreased recently, there were still as many as 153,000 catalytic converters stolen in 2022, and the numbers could rise again. So, what is a catalytic converter, how does it function, and how can you safeguard yours from theft?

What exactly is a catalytic converter?

A catalytic converter is a part of a vehicle’s exhaust system that helps reduce emissions. It contains precious metals like platinum, rhodium, and palladium, which facilitate chemical reactions to convert harmful emissions into less toxic compounds. Early converters primarily worked on oxygen, carbon monoxide, and hydrocarbons to produce CO2 and water vapor. Later advancements also addressed nitrogen oxides.

Do all vehicles have catalytic converters?

If your vehicle is not a classic and runs on gasoline, chances are it has a catalytic converter. In 1975, the government mandated the use of catalytic converters in nearly all passenger vehicles to combat air pollution. This, along with other pollution control measures, significantly improved air quality over the years and led to the removal of lead additives from fuel.

Why do people steal catalytic converters?

Catalytic converters make headlines due to the valuable metals they contain. Each converter holds several grams of platinum, palladium, and rhodium. As of May 2024, prices for these metals were as high as $36 per gram of platinum, $35 for palladium, and $164 for rhodium. Thieves target converters because they can extract and sell these metals quickly, making a profit ranging from $50 to $1,500, depending on the vehicle.

Can you drive without a catalytic converter?

While it’s technically possible to operate a vehicle designed for a catalytic converter without one, it’s not recommended. The car may be noisy, emit strong odors, perform poorly, and potentially suffer additional damage. Driving without a converter is harmful to the environment and illegal in many places due to emissions regulations.

How much does catalytic converter replacement cost?

Repairing or replacing a stolen catalytic converter can cost around $2,000. However, the real challenge may lie in finding replacement parts, as inventory shortages can cause delays of several months. Insurance may cover the cost, but some owners opt to pay out-of-pocket to avoid potential rate increases. Third-party manufacturers offer replacements, but buyers should ensure these units don’t void their vehicle warranty. Some insurance providers only cover factory replacements.

How can you protect your catalytic converter from theft?

Law enforcement efforts have reduced theft, but the threat remains. To protect your converter, consider parking in well-lit and secure areas, installing a motion-activated alarm, or physically securing the converter to the vehicle frame. Engraving your VIN on the converter can also deter thieves, though no method is foolproof.


Q: Can thieves steal a catalytic converter in a minute?
A: Yes, thieves can remove a catalytic converter in less than a minute using a reciprocating saw.

Q: Are catalytic converter thefts on the rise?
A: While theft rates have decreased recently, there were still a significant number of converter thefts in 2022.


Catalytic converter theft is a persistent issue that can result in financial and environmental consequences for vehicle owners. Understanding the importance of these components, taking preventive measures, and staying informed about security practices can help mitigate the risk of theft and its associated costs.
