American Motors used ceramically coated exhaust systems on their Rambler
automobiles back in the early '60s.  They advertised the cars as having
a "life-time" exhaust system.  Admittedly, the 135 HP inline six did not
produce much heat, but they did stand up fairly well against corrosion
and road-salt. The "life-time" exhaust systems lasted perhaps twice as
long a typical mild-steel system.  The problem was that the ceramic
coating suffered from mechanical forces, cracks and rock chips etc would
expose the steel to the the environment and the systems then burned
through.
