Now push the entire tubing against the table until straight to reach its half extension, or natural lie. For optimal installation, install tubing in its “Natural Lie” state, midway between fully compressed and fully extended. This provides the most workable range and the longest service life of the installed flex tubing.

Flex pipes are usually found between the exhaust manifold and the down pipe. They can be as simple as a corrugated metal tube, or as complex as a multi-layer braided or woven metal lattice. Because they protect so many other parts, flex pipes tend to wear out more quickly than other exhaust components, and should be checked for leaks regularly on high-performance vehicles. An exhaust flex pipe adds needed flexibility to your exhaust system, allowing it to bend instead of cracking and breaking.

I have not had any breakage since and it’s been quite a number of years. In part, this might also be because of other work I have done on timing etc, the engine no longer runs very hot.

It could also be a result of rusting, which would weaken the strength of the exhaust pipe and cause it to break easily. The reason this is important is due to the natural laws of physics. When the metal piping of an exhaust system and headers heats from the hot exhaust gasses passing through it, that metal expands. In the reverse, after the engine is shut off, that piping cools, and the metal contracts. Exhaust flex pipe sections are widely available at automotive stores in a variety of lengths and diameters. To answer my own question, while flexpipe does flex, it is not meant to be flexed more than a very minimal amount, enough to compensate for any vibrations in the exhaust system.

Then, spray exhaust sealant on the end of both pipes, slide them together, and tighten the muffler clamps back into place.
