Large Plastic Tube Coming Out of Engine

I'm wondering what this tube is doing. Exhaust comes out of it. Is it a catalytic converter. It doesn't look like it belongs. If it is a catalytic converter is it easy to remove?

Crankcase ventilation tube. Lets blowby from rings and/or turbo seals out of the engine.
Without this you would blow the seals and gaskets out of the engine and have a bunch of oil leaks.
