The photo does not show this but up close to the engine, my exhaust is
made
of industrial type water
pipe from Canadian Tire. 2" o.d. Thick wall steel and heavy but long
lasting.
I used the Racing Beat exhaust flanges as a model and made up a 3/8 or 1/2
inch thick
steel flange to which are welded the first pieces of  2" o.d. water pipe.
From there the other pieces are screwed in: nipples, lenghts and bends, 45
and 90 degrees bends, as needed. From the exhaust flange going down and
rearward, I
have about 12" long of these bends and pipes. The 2" i.d. flexible SS
tubings slip over the last 4"  of pipes and is held in place by the
exhaust
temperature probes and their clamps.

Yvon, that is very resourceful of you. It never occured to me during all
this talk of stainless and Inconel. I may use some in testing this manifold.
Did you use black(bare) or galvanized? So if it is 2" od it must be called 1
3/4? I didn't realize there was such a size. It isn't 2" ID is it?
