To change from an inlet to an outlet you need to restart.

Why not use an opening which can handle flow in either direction?

how i am supposed to do that?

basically i want air to flow in the system when pressure is below atm. and exhaust gases leave from same spots when pressure is high as comapred to atm. pressure

That sounds like an opening set to atmospheric pressure to me. Have you done the tutorials? This is pretty basic stuff.
