I have seen somewhere a header heat shield which is more like "socks" or "bags" or so to keep only a loose contact with the headers and still encapsulate them... EXPENSIVE
It's impossible to wrap it that tight. I'd be interested in the bag type insulator if I was looking at doing this to my jeep. Seems like it might be a lot simpler than trying to wrap that lumpy header.

I imagine that's only a problem if the thing sits around in disuse, but it could be exacerbated by mud. When it's running the moisture cooks off really quickly. With the bike I hardly ever get much rain(use the jeep on those days) and everything is right there in your face, so any mud or anything gets a good cleaning. I could only see it being a problem retaining moisture if I let it parked outside in the fog or hose everything off and then not run it around the block.
When I did the install on the bike I gave my pipes a few good coats of VHT paint first to help that too, just in case. It's not the best paint for anti-moisture, but it's the best poor mans approach that can take the heat. If someone is truly worried about a wrapped header rotting out before the rest of the jeep then getting it professionally ceramic coated before wrapping would be the way to go. ($$$)
Here's one pipe done and the other waiting. That's the bung for a wide band O2 sensor on the crossover pipe. AFR meters are cool tools for dialing in carbs
The darker spots are just water, you soak the wrap to help get it tight when installing. I learned the hard way to rinse the wrap about 5 or 6 times to get all the factory grime off or it'll turn funny colors and takes longer to stop smelling.
