RH77 - Would you not get even warmer air if you placed the heatshield back on, and put the tube behind the header?

Looks like you could make a simple metal strap that would bolt onto the header where the heat shield goes, that way you could keep the tube stationary, and still have the heat shield on...

And the heat shield keeps the header warmer which = better exhaust flow, so you'd be getting two benefits: warmer air and better scavenging of exhaust due to faster exhaust flow.
