My takeaway: The caveat to ceramic or wrap is that increased heat and expansion is counter-productive without creating a clear pathway for escape in an already restrictive system. Hence removal of cats/baffles.

A corollary I've heard is that the temperature at the tip of the exhaust should be hot, such that only one finger's width can tolerate the heat. And that's how you'll know if the exhaust is flowing freely. Maybe just an old 'gear head's' tail....
