Header wrap??

How much are these headers your wrapping? when I took my wrapped Supercomps out to sell them, they were not in bad shape at all. I think the wrap got a bad rap when motorcycles used them on 16000 RPM race bikes and the header would get so hot under the wrap that it would cause the pipes to break down and collapse. The wrap does not go on tight as it does not stretch at all, matter of fact its darn hard to even get it smooth. My wrap you could rotate on the pipe if you turned it. Im still using it off my turbo downpipe.
