Creaking CATs

I listened to the video and that's not the sound I am hearing. Its more like the sound of metal slowly expanding or stretching, like the sound of a metal door opening slowly, or like the sound you hear in the movies when some of an elevator's cables have broken and the remaining cable is straining to support the cab.
I spoke to a tech with Berk and he said its nothing to worry about, so long as the sound goes away when the car warms up. He said the sound was likely caused by the ECU doing it everything it can to warm things up as quickly as possible.
My car is running great and I have no CEL so maybe I shouldn't worry about it. The noise isn't very obtrusive and doesn't last long. If I was listening to the stereo I would never notice it.
