Walker Ultra catalysts® are designed to meet EPA emissions requirements. Available for imported and domestic OBDII vehicles (1996 and newer), you can count on Walker catalytic converters for state-of-the-art fit and performance to keep the engine control light off for emission codes. Whether you need a CARB-compliant replacement catalyst or an EPA-compliant converter, Walker has it all. Walker offers high-end direct equipment and universal catalytic converters for CARB and federal certified vehicles. Check Walker`s parts locator to find your catalyst. Walker CalCat catalysts® are designed to meet CARB requirements in California, Maine, New York and, starting in 2021, Colorado. Catalytic technology provides the right catalyst material and design, including proper loading of precious metals and a high-tech washing jacket to meet the strictest emission standards. For universal equipment covering a wide range of automotive applications, discover all MagnaFlow universal catalytic converters. Professional installation required. If the repair is performed in the State of California or the State of Colorado (Colorado on or after January 1, 2021), you must use a replacement CARB-compliant catalyst for all repairs. This is true even if the vehicle has not been certified legal for sale in the state of California.
Select the appropriate part as specified in the published Walker vehicle application data® or in your state catalog. A CARB-compliant catalyst has been approved for sale by the California Air Resources Board (CARB). CARB emission standards for aftermarket catalysts are more onerous than EPA standards for aftermarket catalysts and require a broader warranty than the EPA. As a result, CARB-compliant catalysts typically use an improved combination of washer layer technology and higher precious metal filler to meet the stricter emissions conversion standard. A CARB-compliant converter will also have an Executive Decree (EO) number/stamp on its body. The stamped number on the converter body must match the correct EO number listed on the California Air Resources Board for Aftermarket Catalytic Converters website. If you need a new catalytic converter, you can make sure you`re getting 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.
California was the first state to mandate the use of CARB-compliant catalysts on January 1, 2009. In subsequent years, other states, including New York (6/1/2013) and Maine (6/1/2018), mandated the use of CARB-compliant converters for certain model year vehicles. As of January 1, 2021, Colorado will be the last state to require the use of CARB-compliant catalysts. Since 1975, vehicles have needed a catalytic converter to meet federal emissions standards. For vehicle repairs, most states require a replacement catalytic converter that meets Federal Environmental Protection Agency (EPA) standards. However, some states have adopted stricter standards that require the use of a CARB-compliant replacement catalyst to meet California Air Resource Board (CARB) standards.

In all other states not listed above, EPA-compliant replacement catalysts can be used for all repairs, whether or not the vehicle has been certified legal for sale in the State of California. Select the appropriate catalytic converter for your vehicle based on recommendations in the published Walker app data or catalog. As an integral part of your vehicle`s exhaust system, the catalytic converter is designed to reduce certain gases and pollutants emitted by the exhaust gases of internal combustion engine vehicles.
A catalyst has a substrate with a chemical coating containing precious metals such as platinum, palladium and rhodium. These precious metals serve as catalysts that treat regulated raw exhaust gases and convert them into less harmful gases such as water, carbon dioxide and nitrogen. States that have mandated the use of CARB-compliant converters usually have emissions tests that vehicles must pass regularly. If you live in a state that requires the use of a CARB-compliant catalytic converter and you don`t properly install an EPA-compliant catalytic converter in your vehicle, you probably won`t pass your state`s emissions test. To pass the inspection, you must install an appropriate CARB-compliant catalyst. If you have any questions, be sure to read your state`s regulations to make sure you`re getting the right converter for your app and location. For repairs in states that require only EPA-compliant replacement catalytic converters, it is also permitted to install a CARB-compliant catalytic converter in your vehicle. EPA has determined that all replacement processors that comply with CARB are automatically considered EPA compliant.
The only requirement is that the part is correctly selected based on the cataloged capabilities or vehicle models listed for the part in the Walker app data or catalog. For precise OEM fit and easy-to-screw mounting, you can purchase all MagnaFlow Direct Fit catalysts to find the best replacement for your vehicle.
