The California Air Resources Board (CARB) maintains a comprehensive database, often referred to as the “Database Cat,” for approved aftermarket catalytic converters. This crucial resource helps ensure vehicles comply with California’s stringent emissions standards. This database allows users to search by vehicle information or ARB Executive Order number to confirm compliance.
Navigating the Database Cat
The database focuses on aftermarket catalytic converters that meet regulations effective January 1, 2009, for both OBD II and non-OBD II vehicles. While primarily designed for passenger cars, light-duty trucks, and medium-duty vehicles, it offers a valuable tool for verifying catalytic converter legality. Users experiencing display issues with Internet Explorer should utilize the Compatibility View setting.
Important Considerations and Resources
CARB provides additional resources to complement the database cat. A list of rescinded or withdrawn Executive Orders highlights catalytic converters that are no longer legal for installation or sale in California. Specific guidance is available for Toyota Sequoia and Tundra models (2001-2004 4.7 liter Sequoia and 2003-2004 4.7 liter Tundra) regarding compliant catalytic converters.
For Executive Orders not included in the database, CARB offers a complete list of approved catalytic converters under the new regulations. A separate Pre-OBD II EO Listing is also available. Information on older, void Executive Orders is provided for reference, clarifying that associated catalytic converters are no longer permitted for sale in California. A dedicated page addresses aftermarket catalytic converters for motorcycles.
