Casey: Yes, you can get a leak at the "Y" pipe. I had that problem some three years ago. The place of probability would be at the accordion section. You will notice some carbon deposit or discoloration at the crack. The crack can be very small, but large enough to make the annoying leaking noise. To get a better inspection, have your DeLorean on a lift and you can get a very good closer look or even use your ears to hear where it is coming from. You can use a small mechanic's mirror to see around areas that is not accessible. BTW, when inspecting be careful not to get burn ... the "Y" pipe can get very hot!
