Hi Tom,
I think hydrogen embrittlement is what you're looking for, and one (possibly
expensive) way to actually do the exhaust manifolds might be to Extrude-Hone
them. Other than their ads in GRM, I haven't actually seen or heard of real
documented flow test results.

http://www.extrudehone.com/price_list2.pdf

They list iron exhaust manifolds at $625.00... Presumably that's per pair.
Best regards,
Theo
