More than usual exhaust air sound on 2000 Dodge Ram 2500

A recent purchase of a 2000 Dodge 2500 with the cummins diesel engine. So this may be a basic question. The truck at 60,000 miles. My question is I noticed the other day more "AIR" noise comming from the exhaust that before. I have owned the truck for 4 weeks, so I am by far not an expert with diesel engines or noise. Power and fuel mileage seem to be the same. Is this normal?

Could it be an exhaust leak? Perhaps all the exhaust is not exiting the tailpipe but instead exhaust is leaking form a failed exhaust box/muffler or a blown out flange gasket.
