Hmmmm--well if you did not go for the "extreme duty " HPC coating, but
needed it, that is the first problem. I can't buy stainless headers for my
current projects, so am fabricating them from 321 SS (not particularly easy
to buy headers in 321 SS anyway), which is the RIGHT stuff for headers.
THEN--gonna have HPC put their extreme duty coating on them, inside and out
for the thermal qualities--obviously not for corrosion prevention. Prolly
gonna insulate the tubes over the coating too, but that's another story.

Heat retention is the true purpose of these coatings, not necessarily
corrosion protection. And the thermal properties of the coatings were what
I was talking to the guys about---
