Well, for us xD's with body-kit-less stock front bumpers, there's always these nice polished aluminum billet grills, which also come in an all-black finish, too... they run about $200 for the set of two...
here's a couple close-up shots of my grills, with my red Cylon scanning eye in motion hidden behind the top grill... In the second pic you can also see the end of one the red trumpets of my ear-piercing air-horns pointing down behind the lower grill!
