WARNING: It is illegal to install any aftermarket part that alters or modifies the original design or performance of the motor vehicle pollution control system unless the part is exempted or has an Executive Order issued by the California Air Resources Board (also commonly referred to as the "EO" number). Installation of parts which are not CARB approved on a pollution-controlled vehicle in the State of California may result in the Department of Motor Vehicles (DMV) revoking the vehicle registration and certificate of ownership (title), refusing the transfer of registration, and/or the vehicle failing smog inspection. Law enforcement may cite you for the use of an illegal aftermarket part and seize your title and license plate.
