If a victim of converter theft, the first thought is often how much to replace a catalytic converter. Catalytic converter replacement cost can widely vary. Just as thieves target converters of higher value, several factors can affect the replacement cost, including the quality of the replacement part, the make and model of the vehicle, cost of labor, and any other additional diagnostic or parts and repairs fees. Most full or comprehensive car insurance plans cover replacement, however, those with liability-only coverage will pay out of pocket. Depending on your location and vehicle model, catalytic replacement costs can run from $1,000 to $3,000.
