Exhaust leak, cracks and soot marks?

I have some sort of exhaust leak in the header to x-overpipe area. I can hear it if I use the old rubber hose trick to channel the noise. Problem is, for the life of me, I can't see any soot or other telltale signs of where the leak is.
Any tricks to ID where the leak is? I think I have read about every thread on the board related to header and cross over cracks.....
My expectation is that I should be able to see some sign of soot around the heat shield of the part with the leak. Or the connection...or something.

BTW the only way I could find the leak was to remove the headers and close off the ends and pump air into the headers while underwater.....

Eddie - interesting pic. Thanks for the info.
Nick - that tool looks like the trick; I'll see if I can borrow or rent one locally. How close can you pinpoint the leak with one?

It has 3 sensitivity settings but you can pinpoint it to the exact point on the flange on the highest sensitivity, it really is that good. So good in fact you end up checking a known good connection now and then just to make sure its working properly!

The first exhaust leak I had was in that area, but it was on the exhaust test tube coming off the crossover near the headers. It had corroded and finally broken off before I got around to dealing with it. I removed the nut from the top of crossover and installed a VW lugnut in its place. Before trying to chase down the more difficult sources of exhaust leaks, check this easy one first.
