only thing I've heard from header wrap is that supposedly it can trap condensation in very humid weather and cause the headers to rust/corrode faster...........don't know if there's any truth to that at all but supposedly that's why you want to coat your headers with proper coating material, forgot what's it's called and too lazy to google.........it's suppose to do the same thing as heat wrap.....
