I'm with BlackVert, go unequal length, you'll thank yourself. The equal lengths are a major PITA to install and work around, and don't justify the minor gain you supposedly get from them. Plus you'll need to run SP boot protectors with the equal lengths in order to not melt wires. If I were to do them again (maybe next year) I'd go with BBK unequal length ones, I've only heard mostly good things about them. As for coating, its supposed to keep more heat inside the tubing and not in the engine compartment, but most people who have them say they get bloody hot anyways, so I don't know if paying nearly double for the coating is really worth it. But if you do go ceramic, make sure they are also coated on the inside, otherwise they will rust from the inside-out (or at least thats what I've been told).
edit: And if you do go with BBK, don't use the gaskets that come with them, they don't seem to last. Get a set of Felpro's and be done with it.
