Catalytic Converter Configuration Universal

For engines built in 1996 and after, these catalytic converters have ribbed stainless steel bodies that minimize expansion/distortion when the converter heats up. The ribs form a channel that protects pads from direct exposure to exhaust gas, plus they keep the ceramic catalyst aligned. Rigid OE-type heat shields add structural stability, and strong 1/2" lap-joints fuse necks to the body (for optimal flow, necks don't extend into bodies). Made in the USA.

Choosing the Correct Catalytic Converter
Determine engine size and vehicle weight (there are legal limit regulations).

2. Determine the type of catalytic converter being replaced:

  • Pre OBD-II converters are for vehicles built before 1996.
  • OBD-II converters must be used on vehicles built in 1996-Up.

3. If the engine has been changed and is not the same model year as the chassis, proceed as follows:

  • For engines older than the chassis, select the converter based on the chassis model year.
  • For engines newer than the chassis, select the converter according to the engine requirement.

4. Does the vehicle have federal or California emissions Required by the EPA, this information is on the emission control label in the engine compartment. The label (examples below) should be visible on the firewall, hood's underside, radiator support, fan shroud, or shock tower.

Note: These catalytic converters comply with C.A.R.B. (California Air Resources Board) emissions standards.
