I bought a billet grille that requires removal of the stock one, in the directions it is telling me to cut the things connecting the stock grille to the bumper, will this ruin the stock grille and if it does is there a way to remove it without ruining it?

 

yer thats right, you'll notice they tell you how to get it out from the front, the bottom has clups but the top is held in by 3 bolts fixed from the inside. You cant get to them due to the impact suppost piece so you have to pull it out and cut them off.

The only way to do it is by removing the whole front bumper, which you dont wanna do just to put a grill on, plus the fixings will be rusty and not come out anyway. Cut the stock one out, you'll be able to silicone or screw it in at a later date if you wanted.
