You may do this experiment at home with an hair drier and a simple piece of paper
Please, take a look at this examples:
Convective Heat - Air Velocity and Volume of Air Flow
About the exhaust rust, well have in my motocross bike(not a street bike, my bike is only for racing, not road legal) since 2008, and no rust at all, but i think it's possible, but i read a lot about damage in the exhaust but never seen a real one.
And in my car i already kill a turbo manifold with thermal coat(it brokes in tow pieces!
i I never thought it was so effective
).
