header wrap? pro's / con's

Will not wrap another set of headers! Even though I did it with the correct amount of overlap, used the stainless bands and painted it with the DEI coating... it still cooked my headers and made them so brittle they cracked at the flanges! The pipe literally split wide open after a burnout one inch from the head. It DID keep a lot of heat out of the engine compartment.

I don`t know how long the guy from Witchitaw had wrap on the headers I bought from him, but their was no cracking or rusting on them. He blew up his engine after spraying it to get it in the 9`s. I rewrapped them after fixing a couple of hammered tubes, still no problem, other than the dam stuff is starting to deteriorate and gets fiberglass in my arms while working on the engine w/ short sleeves. If ur going to wrap ur headers, buy the best stuff u can find. Jegs has some that is supposed to take 2000 degrees constantly. DID I SAY I HATE THE DAM STUFF ?
