Exhaust leak Detection - How Best?

'89 760T -- what's a good way to check for exhaust leaks?
I'm looking for a potential leak at the turbo exhaust area.

Thanks!

Takes two people. Start the car, stuff the tailpipe with a rag, and listen for the escaping gas. You have less than 1 minute to "find" the leak before you burn your fingers.

When the engine is cold you can use your hand in the suspected area. Unfortunately turbos do not stay cool very long. A length of hose that you can hold to your ear and to the suspected area also works quite well. Visually look for blackened areas of exhaust escaping.

Thanks. I looked for blackened areas and did not find; however, the exhaust pipe near two gaskets near the turbo actually has some white coloration? Then felt for air while engine cold and utilized a piece of fuel hose and did not hear any leaking; however, I did hear what may be leaking (very low hiss sound) near the end of the large hose which connects the AMM to the turbo -- on the turbo end. The hose looks like it's starting to break down, so I'll plan to replace it.
