APT sells ball joint exhaust pipe sections.
They work great where you have a moving engine
and a rigidly mounted exhaust pipe.
The trick is proper location.

Subject: Re: Weld Breaks on SS Headers
Doug, I have seen sections of pipe that looked like that may be flexible in an
auto parts store. Only thing is they looked pretty long (about 6 feet). Never
looked to see if they have shorter section though. They did have the correct
"bellows" type shape. Probably in mild steel though. I'll look next time I am
in.
When I fit a new exhaust and header I would like to make sure that I don't get
cracks as well.
I would have thought that a muffler shop would have something universal that
they use in various diameters.

I wish I could find a decent flex-joint that I could add to
my exhaust. Any leads, anyone? At one point, I had
a foot-long section of that cheesy spiral-wound flexible pipe
between the header and the main pipe, but it fell apart after
a couple of years.
If you look at the geometry of headers and how they attach to
the engine, you will see that a rigid header+pipe setup
can apply very high forces to the flanges, studs, etc...
