    A catalytic converter is an essential emissions control part and is a key component inspected during a Smog Check. It contains rare metals responsible for converting smog-causing pollutants that pass through a vehicle’s exhaust system into less harmful compounds. Because these metals have a high recycle value, catalytic converter theft has become increasingly common.

    Experienced thieves can remove a catalytic converter in one to two minutes using basic tools. What can net a thief hundreds of dollars at a scrapyard or recycler can then cost you thousands of dollars to replace, depending on the make and model of your vehicle. Learn more below on how you can protect your catalytic converter and prepare for your vehicle’s next Smog Check.

    • Install a theft prevention device on your catalytic converter – A licensed auto shop can install a protective plate, shield, clamp, cage, strap, or other device to secure your catalytic converter. The device must be properly installed to avoid any damage to the catalytic converter and ensure all identifying information is visible. The device should not be welded or attached directly to the catalytic converter.
    • Mark your catalytic converter – Engraving or etching your catalytic converter with your vehicle identification number (VIN) or license plate number may deter theft. It may also alert a reputable scrap dealer that the device is stolen and can help to identify the owner. If you choose to also have your catalytic converter painted with bright, fluorescent paint, be sure that the paint does not cover any identifying information. Check with your local law enforcement agency for information on any upcoming no-cost engraving/etching events.
    • Adjust your vehicle’s alarm – A well-calibrated alarm can detect vibration and alert you or scare thieves away.
    • Park your vehicle in a safe location – If you have a garage, use it. Consider installing motion-sensitive lights if you park in your driveway. Park close to a building entrance or in a well-lit and high-traffic area when parking in a public lot.

    A vehicle will fail Smog Check if the theft prevention device modifies or damages the catalytic converter or if any required identifying information is not visible. In addition, a theft prevention device should not be welded or attached directly to the catalytic converter. To help ensure the proper installation of a theft prevention device on your vehicle, visit a licensed auto shop.

    Take your vehicle to a licensed Smog Check station to have a replacement converter installed. The replacement converter must be from the Original Equipment Manufacturer (OEM) or a California Air Resources Board approved aftermarket converter with an assigned Executive Order (EO) number that meets the exact requirements for your vehicle. The station will help ensure the correct replacement converter is properly installed on your vehicle.

    Use BAR’s Auto Shop Locator to find a Smog Check station to complete the installation. For assistance with locating a hard-to-find replacement converter, contact the vehicle manufacturer or Smog Check Referee.

    Please note, the replacement converter should be installed as soon as possible to avoid potential problems and damage to your vehicle, and must be installed before your vehicle’s next Smog Check. If the replacement converter is on back order, contact the Smog Check Referee for assistance.
