Im looking at a 2000 explorer sport, but the thing maks a realy low hum wen im on the gas. It sounds like the interferance u would get with the old am radio. When it gets abover 4000 rpm, it turns into a rattling sound. Im thinking a exhaust leak possibly? Any other ideas??

its a auto, the slight hum turns ito a rattling sound when i get on it above 4000 rpm.
If its just a exh leak im not woried about it, cause it seems like a good deal, 70 000 miles on it, for $2500

Exhaust heat shields? My Subaru has various points across the rev range that will either be quiet, buzz/hum, or rattle like hades. That's what causes it for my car.

Sitting still or moving? Neutral or in gear? Why are you getting it up over 4 grand?
