Catalytic Converter Replacement Information&EPA Installation Requirements

When replacing a catalytic converter, it is important to follow the Environmental Protection Agency's (EPA) installation requirements. These requirements are in place to ensure that the new converter is properly installed and will function effectively to reduce emissions.

Here are some of the key EPA installation requirements:

• The new converter must be a certified replacement for the original converter.

• The converter must be installed in the same location as the original converter.

• The converter must be installed in accordance with the manufacturer's instructions.

• The converter must be properly sealed to prevent leaks.

Failure to follow these requirements could result in fines of up to $4,000 per violation.

Determining the Emission Family Number (EFN)

The Emission Family Number (EFN) is a unique identifier that is assigned to each group of vehicles that have similar emission characteristics. The EFN is used to identify the correct replacement converter for a vehicle.

To find the EFN for a vehicle, you can look for a label on the vehicle's engine or under the vehicle's hood. The EFN may also be listed in the vehicle's owner's manual.

If you are unable to find the EFN, you can contact the vehicle manufacturer for assistance.

Finding a Universal Converter

If you are unable to find a direct-fit replacement converter for a vehicle, you may be able to use a universal converter. Universal converters are not vehicle-specific, but they can be adapted to fit a variety of vehicles.

When selecting a universal converter, it is important to choose one that is the correct size and has the correct inlet and outlet diameters. It is also important to make sure that the converter is CARB-certified, which means that it has been met California Air Resources Board (CARB) emissions standards.
