Phil:
You are correct, but this is merely ANOTHER reason to
ceramic coat the headers. Corrosion resistance, better
thermal performance, quieter, better cosmetics, etc.
There are many, many good reasons to ceramic coat headers.
My favorite is the "wow" factor when you lift the hood for your
buddies. =;-)
Cheers,
Vance

I could be wrong on this, but I had always thought that the purpose
of the ceramic coating was more for thermal reasons than
anti-corrosion. Keeping heat in the exhaust helps with scavenging,
from what I've read.
