Black Ceramic coated exhausts

How do you guys that have them find them? cleaning wise and durability? do you think they'll stand the test of time like chrome or do they start to fade and go grey'ish over time? I'm thinking of getting ones of these but don't want to pay extra for black if it's not going to stand up to the usual elements and being broken down at the side of the road.

Don't now about durability, but being ceramic I would imagine they would be pretty good.  They certainly look the part though!

Black ceramic pipes  - year on, still as good as the day they were fitted.  Minimal maintenance - quick wipe over after a wash.  I know mine were done to chrome, so I imagine if it's done by the manufacturer, it'll be at least as good
