headers- coated or not???

If you want a header that's both rust-proof and keeps temps down, invest in a set of ceramic coated stainless steel (LPP, Kooks) headers. Stainless steel is the key.

I agree with RamAir. Ceramic coating offers performance benefits as it keeps the engine bay cooler and increases exhaust gas velocity.

No coating prevents rust. It only delays it. My high-temp ceramic coated Jet Hots began rusting within 3 months.

Header wrap will serve the same purpose of ceramic coating, but will lock in moisture around your headers (promoting rust), and will allow combustible fluids a place to accumulate.

Ceramic coating is generally on both the inside and outside of the tube, whereas header wrap is not. I've always heard that header wrap is a bad idea because it causes the steel to get very hot, which promotes oxidation and reduces the life of the header.

IMO coated is just a waste of money, they are going to discolor or rust eventually. Save the money for something else.
What I've always done and so far have had good luck with it once i get the headers, sanding them then spraying them with VHT high temp engine paint. So far so good on the set I did for my GTO, just some minor rust around where the tubes all meet, (which i can pull these off and make them look new again, and reinstall them all in a couple hours but ive had them on for 5 years and got caught in a couple rain storms
So Id rather save the money, paint them and they will probably outlast the coated ones, and then I can actually repaint them if needed, where the coated ones may be difficult when the coating starts to flake off.
