You didn't say which grill you have, but I installed the upper billet grill with the running pony in about 30 minutes without removing anything but the stock grill. A new grill wouldn't help since they don't include any instructions. There are only 8 plastic push in clips holding the stock grill in place, 2 each on the left and right side and 4 on the bottom . The only thing that is a pain is bending the plastic tabs on the bumper over the grill clips. Since the car is pretty new, the plastic is still very flexible and shouldn't break. My grill just screwed to the bumper with 6 screws. Let me know if you run into any problems, but it is pretty straight-forward after you look at it.
