[Supras] How do I locate an exhaust leak?

[Bob]

I haven't seen a Supra manifold crack... 

Midas was just guessing and probably didn't want the job or they would have
looked deeper and found the problem.

There are only a few places it could leak and most are pretty obvious.  Look
for black soot staining...  that is usually the easiest way to spot a leak.

I have seen O2 sensors back out and leak and the EGR pipe on my MR2 always
would loosen up and leak a little.

Other than that there is a flange where the exhaust hooks up and where the
manifold attaches to the head.  Pretty simple system unless it is a turbo...
not much more difficult but since mine is an NA I can't help you there

Subject: [Supras] How do I locate an exhaust leak?

I have an exhaust leaking sound in the engine
compartment area but can't tell where it is
originating from exactly.  I took it to the local
Midas shop and they say it's the exhaust manifold
which cracked.  Afterward back at home I took the 2
heat shields off the exhaust  manifold but could not
see any cracks ( at least visible to the naked eye)
usingboth a flashlight and mirror to see the back
side.  Can someone suggest a way to locate the exact
position for a leak??  Maybe it's in the down pipe? 
How about using soap solution or will that won't work
due to the high heat ?
