A catalytic converter is an exhaust emission control device that reduces toxic gases and pollutants being emitted from vehicles. Thieves cut them from vehicles and sell them to scrap metal dealers because they contain precious metals, including rhodium, platinum, and palladium. Repairing vehicles form these thefts are over $1,500 each.
