Going turbo, school me on catch can/breather setup.

Ok so I have a rx performance dual valve can on its way. Got it for a deal I couldn't pass up. If I don't like it I'll buy the mm setup.
Now what breather do I need? One way valve in or out on the breather?

You want to do a one way out to relieve crank case pressure. You don't want to be sucking unmetered air into your motor.

ws98ta has a 1LE breather on the pass valve cover.
