Ceramic coating is the way to go. It looks so much nicer and is alot easier to see the condition of the headers, like any cracks or corrosion.

I have ceramic coated UEL headers and also used the head wrap that came with the headers on the dump pipe. I'm glad I coated mine instead of wrapping because the plastic undertray is very close to the headers just before the collector, if I had used wrap, the wrap would easily be pressing on the undertray and would most likely melt it. But as I said earlier, that is with the UEL headers, so EL might be ok.
