    The OD of the core/matrix, or the OD of the cat housing? I assume the former. Let us know what you find.

    What do you mean by the diameter? Aren't the OEM cats oval?

    ah.. it's an optical illusion due to the location of the outlets and the ridge of the weld.

    They are 130mm in diameter, but the ridge of the weld takes the height to 145mm.

    I had some spare OEM cats.
