    M50B25 exhaust manifold 3 bolt flange sizing?

    Hey guys;

    Just wanted to double check, the 3 bolt flange at the bottom of the M50 headers is 2" in diameter, right?

                  rigid pipe/tubing is measured by OD. flex tubing is measured by ID.

                  Should be true for all automotive or aerospace related lines/fittings.
