Ceramic coating stainless headers is the best way to go.
Ceramic vs stainless headers.
I had coated headers on my lt1 camaro and like one of the other posters accidentally bumped into one of the primaries with my hand after the engine had run for some time.
Keep in mind that most ceramic coatings on headers do eventually come off and headers with that coating is not going to last forever and headers tend to eventually rust.
Also since the heat is staying inside the headers the exhaust gases will be hotter and will flow more remember as air cools it becomes more dense.
I also agree with the lower temps.
They don t rust so the coating won t flake off like it can on mild steel headers.
Below are some examples of how ceramic coatings can help increase your vehicles overall performance.
Even if you are already using a high grade stainless steel or titanium set.
Stainless will radiate more heat into the engine compartment than ceramic coated headers will.
Ceramic coatings can increase performance ceramic coatings can help improve the performance of your headers turbo parts and exhaust pipes.
