Not quite... The best insulator is no air... Double walled evacuated stainless pipes anyone?
Interestingly the Previa's header is twin wall stainless. In the sae paper they only mention weight (as opposed to cast iron) and noise as a reason for the double wall.

You and me need to meet up, build a vacuum chamber, and start selling exhausts! :P
I knew about the evacuated pipes, but I have no idea if we could make them realistically.
