Magnaflow Pre-OBD II 49-State & Canada Spun Catalytic Converters are designed for use in tight places, such as on street rods. Magnaflow fabricates each converter body from a single CNC-formed and laser-welded tubular section, which is then spun into a round converter body shape. Each converter is literally manufactured around the ceramic catalyst, securely tucked inside, and necks down to thicker gauge material at the inlet/outlet for maximum durability. 49-State catalytic converters are not legal for sale, installation, or use on licensed vehicles in the state of California. Made in the USA

Selecting The Proper Universal-Fit Catalytic Converter For 49-State and Canada:

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-OBDII converters are for vehicles built before 1996. If the vehicle was built in 1996 or after, a OBDII 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 converter is a 2-Way, 3-Way, or 3-Way + Air. In order to properly determine which catalytic converter to use on certain applications, it is necessary to determine the type of catalytic converter originally used on the vehicle. This information (required by the EPA) is included on the vehicle emission control information label located in the engine compartment in a visible position on the hood underside, shock tower, radiator support, fan shroud or firewall. (An example is shown below.)

  • Two-Way (Oxidation) = OC or COC
  • Three-Way (Oxidation Reduction) = TWC or ORC
  • Three-Way + Air (3-Way Plus Oxidation) = TWC/OC or ORC/OC
