My 1987 Bronco 2 has a funny sound while going down the road around 40-60 miles per hour. It sounds like: phissssh, almost like a air leak in a air pressure hose that's leaking. The truck still has the orginal cat and a small muffler with a short 18 inch piece of pipe. Do you think the cat is partly plugged/too much back pressure???
