Just tried this and it worked really good so wanted to share.
Get some 1/2" hose, a funnel, some tape and a rag and a shop vac. Put the hose in the bottom of the funnel to make a ghetto stethoscope. Put the shop vac in one of your exhaust pipes and tape it air tight. Clog the other pipe with the rag and turn the vacuum on. Use the funnel/hose to listen for leaks. Worked REALLY good for me. The farther away the vacuum from the car the better. You could do it with the car cold and just parked in your garage which is the beauty of it.
