There ARE stainless steel exhaust systems available. I have personal
experience with their application for at least 15 years now. In my
29 years experience as a fleet mechanic, supervisor, and manager,
I have observed no tendency for stainless exhaust systems to crack
at any greater frequency than non-stainless systems. An appropriate type
of stainless steel is an excellent material for exhaust systems.
