Sounds retarded, but in my vast and optimistic imagination it seems to work lol
There are ways you could make the exhaust wrap work, but it requires a bit more effort to make sure that you don't let moisture damage the SS-303 (I think that's what most ppl here use for their dp's).

Most people just wrap it and forget it, you should at least hit it with some silicone spray paint thats made for high temps. The exhaust will help cure/bake the paint as well. If it were me doing it, I would probably coat them in something that can protect against corrosion and handle high heat before anything though. Not sure if por15 would work for this application, but if it does I would hit it with por15, then some VHT header paint, then wet wrap them, let them dry and then finally hit them with some high temp silicone. Seems like a bit too much effort though.

Ceramic coating would be a much easier and headache free route and probably works better too.
