Exhaust leak, IMO.
It's not a very good design for holding together and you are venting exhaust drive pressure somewhere.
I just had my turbo out last weekend for those new bellowed up pipes and found that the exhaust housing had two loose bolts holding it to the flange. Black soot coming out the back of the turbo and spraying the firewall behind the turbo. I couldn't see it until I pulled the turbo out. (Kris, I had it unbolted in about 15 minutes, but spent next 1.5 hours trying to get that clamp on the exhaust Y-pipe dislodged from 80k miles of clamped down hard. I didn't have a new one and didn't want to bend it, so I had to be gentle with it. It's easy to believe your 19 minutes with a little practice.)
Those brand new Ford style up-pipes that I installed last spring were black and leaking all over again.
Venting drive pressure all over the place and costing me boost pressure and fuel economy.
Hopefully these bellowed pipes will do the trick and not crack or something.

I'm hoping I hit a "truck pot" on one of those million $ slots, then I won't have to worry about exhaust leaks, at least for awhile anyway!
