Hi Mark,
Your system has a little more room to flex than mine. I think the most
likely place I will see a crack is where the short tube are welded to
the large can.

Finn,
Maybe that's why some of the aftermarket flanges are one piece. That's
how I made mine for that very reason. So far, so good.

Ground running won't necessarily get you into that thermo cycle range.
Seems you consistently have to get above 5,000 RPM before anything
happens.
No expansion joints: it will crack.
Unless you use ridiculously thick material. Which is probably why the
stock Mazda manifold is so heavy.
