I'm planning on ceramic coating my headers soon. I didn't have the best luck with high temp can paint. It was probably in the prep (removing all old chrome). To best prep for paint you would ideally need to have it blasted... and if you're doing that, you might as well ceramic coat as you're halfway there. But it's not cheap. I'm not sure how my local rates compare, but my quote is in the $250 range for 4-1 header. If you have the money, ceramic. If not, prep by hand as best you can and paint it for a season/year until you can ceramic. And I've seen some high temp can paint jobs last fairly well, but mine didn't. I'm going for black, but here there are some 'silver' ceramic options out there too if you want it to resemble chrome.
