Keep an eye on them Cody. And if/when it starts to get mangy, consider getting them coated or going back to the stock sheetmetal.

Oh, I heat wrapped my previous manifolds 8 or 9 years ago and they were fine. Not sure if they will rust faster or slower now that I live in the Bay Area, but most things on my car rusted more when I lived in Reno, due to the drives over the hill.
I use a sealant that helps prevent liquids from soaking into the wrap and I do retain the stock heat shields so it should be just as safe and probably more effective than ceramic coating.
The sealant and wrap does offgas some nasty fumes on the first hard drive, which is why I banged that out Monday night after the install.
Here are pics of my old manifold vs. the new one. The heat wrap on the OEM one would be in better shape but years ago I was installing and uninstalling the manifolds a lot and ripped it.
