I have an inconel tangential manifold/muffler on my 20 - photo attached

Flange, but are welded on the outside - not on the inside.  Although

having the tubes go through

the flange may have made the welding easier, I'd guess that once you get

that weld bead around

there the resulting strength is no better then butting it up and wleding

it.  Seems it should be

welded on the inside end so the flange can support the loads on the tube.

There obviously will be

significant thermal stress set up and the unit expands and the engine

doesn't.

Atkins has the same approach on his 13B and it seems to be fine.  The

distance between the ports

is much less on his.  Am I worried about mine?  Yep.  Short redoing a very

expensive piece, I'll

do frequent inspections.

No photo was attached Al. BTW if you turn off your html your messages will
print

Not a question of liking it or disliking it. It just screws
up everything. Probably just another dirty trick on Microshits part
in an attempt gain absolute control over something. Anything! :)
