The reason for Ceramic Coating is this... One it does not stain or blue from heat or oil and 2 it dissipates heat extremely fast. I have heard headers that were ceramic coated inside and out be cool to the touch within minutes.

Well, I guess if you like burnt fingers go ahead and touch it a few minutes after you shut it off. I have the ceramic coated header on my Sammy, and it don't cool down that fast. It's nice and all, and helped keep the rust down (it still rusted a tad because NY roads are basically friggin' piles of rock salt), but stainless is stainless.
My latest kick is rust prevention. Rust makes me sick. I've put a lot of time, money and effort into building my trucks, and rust seems to creep in. I don't want to invest $20K into my truck just to watch it turn into a pile of iron oxide. I'm swapping a out a fair share of hardware for metric 8 and higher equivelent stainless, and using liberal amounts of anti-seize.
