Actually fizzicks says so. The wasted energy in the exhaust is heat
energy -- why do you think it's exiting so fast! Gasoline + air + spark=
lots of heat which makes the gases get really big. If the exhaust
temperature was reduced (say, lots of refrigeration) to that of the
intake, the pressure would be the same too. Temperature makes the
pressure rise. Without the temp, no pressure.

Exhaust temp out of a turbo drops a lot too, representing the heat
energy extracted from the exhaust.
