Schumacher header exhaust coating
Have your headers built outta stainless. Between my exhaust and coating guys...I have systems that'll never "crap-out". I have both ceramic/mild steel, and stainless stuff.
Here's a set of ceramic-coated [2-step]headers that got a butt-load of oil dumped on them[blown head gasket]...and what they looked like after a 1/2-hour and some 3XXX steel-wool with some thinner. That was 2010....and they still look like new.
