catback exhaust heat retention?

[JShadzi at aol.com]

Fiberglass exh. wrap is not going to catch fire, esp. on the relatively low heat of an exh system.  I've used in on DP's, its really designed to be wrapped around a header, but as Jim pointed out, it can rapidly increase corrosion and definitely a no-no for cast irons which will crystalize and greatly weaken with the stuff on it.
