The engine does not pull air into it, the air is pushed inside because the atmospherique pressure is greater than the pressure inside the combustion chamber.

Exactly right, the same follow equations apply for compressed air pipe and vacuum pipe. The important thing is maintaining a constant surface cross section. The Tee even with an improved inlet radius can't do that. The turbulent area in the back of the tee is affected by flow velocity increasing in size. The higher the flow velocity the smaller the effective cross section.
