To wrap or not to wrap...that is the question.

You should do a thread search on this topic, because I distinctly remember reading a good one about it. In a nutshell, some really experienced guys on the board said that wrapping headers often move the heat downline to the cats and overheats them, doing damage.

I had a hose (can't remember if it was an AC hose or a power steering hose right now) that was touching my driver's side aftermarket header and the mechanic wrapped that hose (not the header) and zip tied it away so it didn't touch.

I would not throw caution to the wind and wrap them if you have no urgent need to do it. Ruining your cats would be a very high $$$$$$ consequence.
