Break in with TTIs

I'm going to look back in the last issue of Mopar Action.
I THINK I saw a stainless exhaust system ad in there.
That is something I have wondered about.
The extra cost of coatings might not be any less than the extra cost if TTI made their systems in stainless.
TTI exhaust is aluminized. TTI headers have to be coated or plated for rust resistance?
No better for less heat in engine compartment, but the rust problem would be solved.
Might make too much sense.
