Should I use a Header Wrap?
NO! ABSOLUTELY NOT. There is nothing that will damage a header faster than the use of a header wrap, other than attacking it with a hammer or shot gun.  As advertised, these wraps do keep the majority of exhaust gas temperatures within the header.  The result is the wraps will prohibit the header tubing from cooling properly.  If you reduce the ability for headers to dissipate adequate heat properly, the result will  be premature failure of the metal.   Depending upon the application use and temperatures involved, the life can be reduced to only a few hours.  We consider exhaust wraps to be the header manufacturer's best friend.
