I think even Berk does not recommend doing it. I'm still on the fence about this one.

Yes, do not wrap your cats in header heat wrap. You will trap too much heat in them and possibly cook them.

The wrap is most commonly used for headers to keep the heat in them and not cooking other components on the car that are in close proximity.

What it also does is keep the exhaust velocity up by keeping the inside of the header hot. This works incredible in a turbocharged application due to the fact that turbos are driven off of heat.
