Gelo,
Sorry for the delay, but I can’t seem to find this item. I did find the another one not finished yet. It was Silver soldered and the open diameters are 5/8. This one has a tracing of the .OS .21 outboard. If this would work. $8 plus shipping.

Hi Ron thanks but I don’t think that would work, I’m trying to adapt a header for a side exhaust thundertiger .21 I was able to machine and fit one but can’t find another one reasonable. All I see are Mac side pipes and they’re priced ridiculously. Thank you anyway. Best wishes Gelo

Gelo,
What I have looks exactly what you need if the diameter works. You can trace your current pipe flange onto this one and cut to fit the flat manifold mounted to motor.
