Well although the crossover repair did help, it just still wasn’t sealing right, and it was starting to look like a “Ray Charles welding art exhibit” that I decided to order a new crossover from banks last week. Finally showed up this afternoon, so I pulled the old on off and and went straight into ceramic coating. I did one layer of primer and two top coats. Bolted both sides onto the manifolds and tacked it in place. Welded it up on the bench and added a bung ok the drivers side then hit it with one more top layer of ceramic coat after the welding.

Then re-wrapped it with the original titanium heat wrap.

Pulled the pyrometer out of the up pipe and brought the harness over to the driver side to reach down to the bung on the crossover.
I’m really liking the bung route instead of using the exhaust manifold, sure it’s about 4-5 inches further from the combustion chamber, but especially with all the heat insulation it’s still a very accurate reading. Not to mention it’s a lot safer modifying something like a crossover than an exhaust manifold that’s difficult to remove, and no metal shavings...
