I agree with dewynter. I have the exact same headers as he does, but without the ceramic coat and it's my daily driver. It seems to do just fine.

sorry, i meant to specify and inside and out coating.

okay let me start over.....first off for a daily driven car it is in my opinion that it would be in best interest to have the headers coated inside and outside of the header. Your non-coated headers are not rusted all to hell? Thats a marvel to science then...headers (some metals, what kind of headers are you guys runnin?) rust because of heat (not moisture).

Do what you will its a free world. Its just that a lot of people pay 420 bucks for some headers (LTs) and then the dont throw on a coating with it, 4 years down the road they wonder how could it be possible the the metal cracked? Coating inside and out also reduces strees cracks, coating (inside and out) will help the headers to last longer, it reduces a lot of "bad" things and increases all the good things

I don't know, I just assume that owners want parts to last longer and look the same with min. wear and tear.

Thoughts?

It seemed obvious to me that when you said "coated" you meant what people normally do... cera-metallic coating inside and out. Not sure why it was interpreted any other way.

In addition to the very real positive factors in cera-metallic coatings - reduced under hood temps, reduced surface oxidation from high tube metal temperatures, reduced stress cracking and heat cycle fatigue, better appearance - the coatings also improve performance by keeping exhaust gas velocities high, increasing scavenging gains.

I wouldn't do it any other way.
