Best way to find exhaust leak?
Ive got an exhaust leak on my truck and cant seem to figure out where from. The motor and cats were replaced recently. The noise is most noticible when starting the truck with the window open. I would think it would be the exhaust manifold as that should have just been bolted down tight with a new gasket. Plus it doesnt sound like a manifold leak, its not really audible in the cab like manifold leak ive heard. So whats the easiest way to determine the leaks source?
Thanks in advance for any help, i hate an exhaust leak. Makes me feel like im driving a old beater truck

That's what works best. I use compressed air myself @ about 15-20 lbs, - only because I have the fitting reducer for the tailpipe. I know those Rigid shop vacs will plug right tho lol.
Yep, soapy water on the seams reveals all.

jbrew - Where did you get the fitting to connect the compressed air to the tailpipe? This seems like a good way to get the exhaust system pressurized. Also, I have a dual exhaust - any good way to plug the other side? I was thinking of using a big sponge with a plastic bag wrapped around it.
