A vehicle’s catalytic converter takes in raw exhaust from the vehicle’s engine. It then converts the harmful chemicals in the exhaust to carbon dioxide, nitrogen and water vapor. The process reduces harmful emissions into the air. Federal law has required vehicles to include catalytic converters since the 1975 model year.
The devices contain a “honeycomb” structure that, when heated up, causes a chemical reaction that converts the harmful gasses to less dangerous ones. The honeycomb is made of three rare and expensive metals: platinum, palladium and rhodium.
Catalytic converters are attracting thieves because of the prices fetched by these metals. An ounce of rhodium sells for more than $15,000, while palladium goes for more than $2,100 an ounce, and platinum is worth more than $1,000 an ounce. Online sellers of stolen catalytic converters can fetch up to $1,500; thieves net an average of $200 per unit.
Theft of catalytic converters is also a low-risk crime. A thief who knows what he’s doing can remove one in just a couple of minutes. Manufacturers do not stamp serial numbers or other identifiers on them, so a stolen converter is very difficult to trace.
