I think it looks pretty good but not great. I would probably leave it because it looks like there might be holes in the bumper where the ends of the "decorative grille guard" mounts. It's probably easier to live with it than to try to remove it.
Here's some fuel for your fire: Get an exhaust! The painted bumpers looks great but the rear is begging for a new exhaust/exhaust tips. Do it! All the cool kids are doing it.
