The primary catalyst is integrated in the Exhaust manifold. Some people (FocusBoy58 comes to mind) have changed the exhaust manifold with one of the catless aftermarket pre 2011 2.0 L duratec headers, but if you were concerned about emissions and or vehicular inspections its best to leave the main cat alone, although PZEV vehicles have a secondary catalyst behind the first one and ahead of the resonator and mufflers.
