...just the headpipes in the engine compartment. The heat has to escape somewhere. Normally the heat radiates away right from the pipe. The idea of header wrap is that by insulating the pipes in the engine compartment, the heat is forced to conduct along the pipe and gets radiated away farther down, where it won't raise under-hood temperatures.
If you wrapped the whole length of the pipe, there'd be no place for it to radiate away, and you'd be back where you started -- except with hot wrap instead of hot metal.
And header wrap will shorten the life of the pipes under the wrap, because they'll get considerably hotter. But if you have problems with high under-hood temperatures, it might be a good tradeoff.
