Is an exhaust leak common on 97 Jeep Wrangler 4-cylinder?

Exhaust leaks are relatively common on older vehicles, including a 1997 Jeep Wrangler 4-cylinder. The constant vibration and exposure to heat and elements contribute to the deterioration of the exhaust system components (pipes, manifolds, gaskets). While not guaranteed, it's certainly not unusual to find an exhaust leak on a Jeep Wrangler of that age.
