Start the car. Have your buddy hold a towel or thick rag firmly over the
tailpipe(s) to build up some pressure. Not TOO tight... don't want the
muffler(s) to explode.

Listen for whistles or similar noises where the exhaust is leaking out.
If you can reach, hold your hand near the various joints and feel for a
rush of exhaust from the leak.

Don't burn yourself, and stay away from moving parts (fan, belts).
