Charlie,
Sadly no, the cut went through about 3/8 inch inside the end of the tube. This is where the weld will be critical as in the type of rod used as it will cop all the heat. The slip join at the bend can be reused to go into the 45 degree bend. Neil.

Can anyone tell m,e the exact metal used in the stock exhaust manifold? I have cut one in half to reverse the direction and it appears to be S/S outer with inconel inserts. It will help to know before I weld back together with the correct rod. As shown the weight is now approx 10 lbs and I am impressed with the build of the manifold, --- much better than my version, and will be not much heavier.

Were you able to preserve the iconel(?) stubs and slip joints where the 3 ports exit the cast plate? I'd bet the slip joints are essential to the system working correctly and surviving.
Looks like you found the one at the exit bend. :-)
I tried to use the flywheel end exit to advantage on mine; my pipe goes down/aft to an Aeroturbine muffler I managed to keep within the cowl. Not yet flying, so can't comment on reliability/success.
