No, the monotone option on 03 and 04 was one complete piece painted the same color as the car, along with all ground effects with that option.
The standard (non-monotone option) had a textured gray ground effects, lower front bumper cover (resulting in the 2 piece bumper cover), and a textured gray Pontiac bezel over the license plate.
Here is a car exactly like mine with the bumper cover I am speaking of, its a one piece bumper cover.
