Missing turbo part? Help!!!

I was told something was missing off the exhaust side of my turbo. He said it was where the downpipe hooked to. Every one I see is the same way? Here is a pic of what mine looks like.

He was talking about something that went like around the lip or something where the turbine is.

damn that is kind of odd...there should be somethin for the dp to bolt to.

heres a crap shot of my turbo on the exhaust side....you can see where the dp flange would bolt to

WHat does the down pipe do?

What size turbo is that?

the downpipe is the pipe that connects the turbo to the exhaust.
