... Has anybody considered having the interior wall of the exhaust pipe ceramic

them recommended that the exhaust pipe be done as well, but it needs to be
done while new, as it is impossible to properly clean exhaust residue from
the inside of the pipe.
I don't think that last statement is exactly true. Pickling solution (main ingredient: phosphoric acid) has long been used in industry to absolutely clean carbon steels before painting. The slight etching it does to the surface has a lot to do with the exceptional durability of factory automotive paint jobs.
What I can't tell you is how SS321 will respond to pickling, or whether ceramic coating will adhere as well to the etched surface as paint does.
Hope this is some help.
