Slant Six Exhaust Mannyfold

Thanks! I'm wanting to get one above 2". I would love to get one in the 2.5" neighborhood, but I don't think that's happenin. The problem is the neck area under the cast in flange. It necks down well under the OD of the flange, so trying to bore the ones that are "around" 2" much over that and I think the neck area gets real thin or sees daylight. I have a good welder friend that I may turn to if I cannot find something......but I am like you. I think larger outlets are out there.
