The entire SS exhaust system was removed by my mechanic is less than one hour on Saturday 3-Feb. That's from the manifold back to the tip. Remember there was no welding of any kind involved. Some bolts were cut, and some tubing cut as well. Everything put back together in another four hours the same day, along with some other minor cleanup and inspection and test drive. (damaged braided fuel line noted and replaced, for example...)
I had sourced stainless steel clamps from Amazon, as even TimeValve couldn't find them:

The manifold nuts were replaced with German DIN 14441:

The replacement center muffler section from TimeValve included a full set of donuts so now I've got spares.
Unfortunately in the eyes of a skilled mechanic while on a lift, a bunch of other issues noted, not too surprisingly since the restoration was ~24 years ago.
