How to Protect Your Vehicle from Catalytic Converter Theft

Why Are Catalytic Converters Stolen?

Catalytic converters are stolen because they contain expensive precious metals (rhodium, platinum, palladium). Thieves can remove them in under two minutes using basic tools, making them attractive targets despite declining theft rates.

What Is a Catalytic Converter?

A catalytic converter is an exhaust emission control device legally required on all U.S. vehicles manufactured after 1975. It's bolted to the exhaust pipe beneath your vehicle and converts toxic gases into less harmful emissions before they exit the tailpipe.

How Much Does Catalytic Converter Replacement Cost?

Catalytic converter replacement can cost between $900 and $4,500, depending on your vehicle's make, model, and year. According to ConsumerAffairs, the average replacement costs $2,900. State Farm data confirms this average, excluding lost wages and alternate transportation costs while your vehicle remains out of service.

Which Vehicles Are Most Targeted for Catalytic Converter Theft?

The most stolen catalytic converters come from trucks, SUVs, and hybrid vehicles. Carfax data analysis identifies these top targets:

1. Trucks (High Ground Clearance)

• Ford F-Series (F-150, F-250)

How Can You Tell If Your Catalytic Converter Was Stolen?

• Engine sputtering and rough ride quality

• Pungent exhaust smell resembling rotten eggs

• Check Engine light illuminated on dashboard

• Visible missing parts beneath the vehicle

What Are the Best Ways to Prevent Catalytic Converter Theft?
