One thing I can think of is the corrosion resistance. Also, stainless steel conducts heat very poorly, which in turn would keep your exhaust gas hot and at a higher velocity.

what if you cermaic coated and wrapped? would this just be redundant? i like the idea of ceramic coating for corrosion redistance, but heard the wrap will hold the heat in the exhaust better.

Well sainless is a bit harder and the nickel in it is what makes it stainless. The carbon in stainless will still cause surface rust over time. Stainless melts at about 2500 as carbon is about 2200 if that makes any difference. Stainless is heavier per sq foot and will crack easier due to it being harder and not flexing as much. Stainless looks nicer but is much more exspensive to use and repair. I work with both on a regualr basis and stainless is only used in high acid or base applications and where flourides and chlorides are used. I would go mild and have it coated for ease and cost.

i would recomend that you swain coat every thing. the wrapping can deterorate over time. i have also seen where the wrapping when used with a coating, destroy the coating

Wrapping is bad for the header in general. But if underhood temps are a concern(example land speed or road race car) then coating and wrapping are the way to go.
