Thanks for your reply,
I’m located over here in the UK, so perhaps not quite as ‘hostile’ an environment as MN. I don’t doubt the effectiveness of the Jet Hot type of ceramic coating, all the reports seem to be full of praise. The only issue is cost over here in the UK, as there aren’t an awful lot of companies providing this service over here and so prices are so much more than you pay in the USA. If it wasn’t for the need to test fit and ‘adjust’ headers prior to coating, I’d get them coated in the US prior to shipping over here.
I actually priced up the cost of buying a set of mild steel headers and getting them coated versus the cost of getting a set made in stainless over here, and the stainless option is only around 10-20% more. Sure even stainless headers don’t last forever due to the internal erosion problems, but I’d expect them to last longer than coated mild steel ones.
Your offer of lending me a pattern is much appreciated, thanks. I think the cost of two way shipping unfortunately rules that one out.
I’ll keep everyone posted if I find a source for stainless steel off the shelf.
Cheers,
Neil
