Grill Guards exist, but, because they are merely cosmetic, and have been causing more damage in collisions than they prevent, and, they ruin the approach angle when off road, essentially, we don't get them. (A few exceptions, but most are converting from earlier mistakes, etc...)
Instead of cosmetic grill guards, we like real steel bumpers...as these give actual protection, as opposed to the "mall crawler" look.
For around the same money you'd spend on a decently made guard, you could get a Shrockworks bumper
www.shrockworks.com The site may not reflect it, but they sell 2005 versions (Pics in Manufacturers Row section)
Good Luck!
PS - Ditch the aluminum step rails too, they get bent when you go off road too...and you can't jack from them....and get steel sliders instead.
PPS - same for the mud flaps....
Seriously - do all of the above, and your X is ready for the dirt!
