I can't speak to the JetHot finish or warranty except to say that my own 340 headers were coated in their black finish several years ago and still look great (but I haven't put more than 3 miles on them either).
3 Miles..........Several Years...........What up with that Leanna :???:
I think fwaugh should send those TTI's over to you for a good old coating from a FABO member with a superb rep.....
Nothing like a small business to give you the best service :poke:
Good luck with whatever you decide :happy10:
