*When purchasing or installing a California-approved catalytic converter, the TEST GROUP/EFN number on your vehicle`s exhaust sticker and PART NUMBER must match the application provided. Below are instructions on how to select aftermarket catalytic converters that have been approved for use in California and learn how to choose the right catalytic converter for your vehicle to meet your state`s emissions regulations. If you need a new catalytic converter, you can make sure you get the right part if you know if your vehicle needs a CARB-compliant converter or an EPA-compliant converter. Follow these simple steps to determine the type of catalyst you need. If you have any questions, check your state regulations to make sure you get the right converter for your app and location. California was the first state to mandate the use of CARB-compliant catalysts on January 1, 2009. In the following years, other states, including New York (6.1.2013) and Maine (6.1.2018), made the use of CARB-compliant converters mandatory for certain model year vehicles. Starting January 1, 2021, Colorado will be the last state to request the use of CARB-compliant catalysts. Converters do not fail on their own.
Failure is usually a symptom of a bigger problem. For this reason, it is important to identify the cause of the error and perform the repair before installing a new converter. Walker`s CalCat catalysts meet CARB requirements® in California, Maine, New York and, starting in 2021, Colorado. Catalytic technology provides the right material and catalyst design, including the right loading of precious metals and a high-tech washing jacket to meet the strictest emission standards. As a result, CARB-compliant catalysts typically use an improved combination of washing coating technology and higher precious metal load to meet the stricter standard for emissions conversion. A CARB-compliant converter also has an Executive Order (EO) number/stamp on its body. The number stamped on the converter body must match the correct OE number listed on the California Air Resources Board`s Aftermarket Catalysts website. CARB adopted revised regulations and evaluation procedures in October 2007 for the approval of new aftermarket catalysts sold in California. The requirements apply to all new replacement converters built after 1. January 2009 for sale or sale in California.
The requirements also stipulate that certified used catalysts can be sold from 10 July 2008. This means that no used converter can be legally offered for sale, sale or installation in California after this date. The California Air Resources Board, with the support of aftermarket catalyst manufacturers, has developed a database to store and retrieve information about aftermarket catalysts that have been approved for use in California. These catalysts comply with the new regulations that came into force on 1 January 2009. The database is currently under construction and contains some of the catalytic converters approved for OBD II vehicles. Once completed, it will also include catalytic converters for non-OBD II vehicles. In all other states not mentioned above, EPA-compliant aftermarket catalytic converters can be used for all repairs, regardless of whether the vehicle has been certified legal for sale in the state of California. Choose the right catalytic converter for your vehicle based on the recommendations contained in the published application data or Walker catalog. * Toyota: Please follow this link to see the legal catalytic converters on 2001-2004 4.7 liters Toyota Sequoia and 2003-2004 4.7 liter Toyota Tundra.

The products meet the requirements of the California Air Resources Board, New York DEC, Colorado CDPHE replacement catalysts listed as cataloged. Aftermarket catalysts must be exempted from California`s anti-tampering laws in order to be legally sold and installed in the state. If a replacement catalytic converter proves to be durable and meets vehicle emission control requirements, it is granted an Executive Order (EO) that allows it to be installed in certain emission-controlled vehicles. To determine the correct catalytic converter part number for your vehicle, you need its make, model, model year, engine size, and test group/engine family. To access Orders in Council that are not posted in the database, please consult the complete list of catalysts approved under the new regulations. To access the decrees only for pre-OBD II vehicles under the new regulations, please consult the list of pre-OBD II OEs. Information on the decrees adopted under the old regulation can be found in the consolidated list. All orders in this summary list are void and are no longer in force and in force. The catalysts they cover will no longer be available for sale in California as of December 31, 2008.
Similarly, the used catalysts they covered will no longer be available for sale in California as of July 10, 2008.

A catalyst consists of a substrate with a chemical coating that contains precious metals such as platinum, palladium and rhodium. These precious metals serve as catalysts that process controlled raw exhaust gases and convert water, carbon dioxide and nitrogen into less harmful gases. Documents related to the Commission`s adoption of new requirements for replacement catalysts include, but are not limited to, the announcement of the public hearing, the staff report and the regulations.
