Greg,

How do you keep the exhaust manifolds so nice & white? I read they are originally porcelain coated?? Mine are thoroughly browned after 215,000 miles.

Maybe a little white high temp spray paint? POR 15 or another brush-on paint?? I suppose removing them, blasting & "jet hot" coating would be the best way, but I'm not ready to put that much into just a color change.
