Magnaflow OBD-II 49-State & Canada Universal Catalytic Converters

Selecting the Proper OBD-II Universal-Fit Catalytic Converter
Determine engine size and vehicle weight first. Converters are listed according to legal engine size and vehicle weight. Determine the type of converter being replaced. PRE OBD-II converters are for vehicles built before 1996. If the vehicle was built in 1996 or after, an OBD-II converter must be used. If engine has been changed and is not the same model year as the chassis, proceed as follows:

• If the engine is older than the chassis, select the converter according to the chassis model year.
• If the engine is newer than the chassis, select the converter according to the engine requirement.

Check whether the vehicle is Federal or California Emissions. Required by the EPA, this information is on the vehicle emission control information label (example shown below) located in the engine compartment in a visible position on the hood underside, shock tower, radiator support, fan shroud, or firewall.

Note: Federal emissions 49-state catalytic converters are not legal for sale, installation, or use on licensed vehicles in the state of California.
