Exhaust leaks make a ticking sound when the engine is reved or if you are lucky you'll heard the loud unmuffled sound as exhaust exits the leaking area.

I you can't get under the car, lay on the ground in a position where you can heard and see the exhaust. Have a partner to rev the engine with the a/c on (not too high -don't want to damage the engine ), you will then be able to hear the exhaust leak.
