exhaust leak

i have a 2002 f250 SD 4x4 with a 5.4 auto, im getting an exhaust leak on the passenger side when under load. cant duplicate the leak while revving the truck, revving it in 2nd gear, causing excessive backpressure by closing off 95% of the tail pipe opening, just cant reproduce the leak when the truck isnt moving, it is most pronounced at highway speed at around 1700-1900rpms. i have laid under the truck with a trusted person in the seat reving it and i cant feel any kind of leak. am i dealing with the broken mounting stud problem?

check that back two studs closest to the firewall on the passenger side, that is where they usually brake. You should be able to see up there from underneath.
