Hey all, I bought used Active Autowerke headers quite a while ago and I'm finally getting around to installing them. This will be the most challenging thing I've done to my car so far but I'll have some friends to help me out with the process. I have a couple quick questions about the install though.

For the install, is the only new item I need the header gasket http://www.turnermotorsport.com/p-17...60-z3-z4.aspx? Or do I need new everything like this http://www.turnermotorsport.com/p-58...4-engine.aspx?

Also, I assume aftermarket headers must be either ceramic coated or painted correct? I can't tell if these were previously coated and just worn or not coated at all. Here's one of the headers, by the looks of it would I have to paint/ceramic coat these? What is the best and/or cheapest way to go about doing this?
