Have seen two styles. There is a layover style and a replacement style. What is the main difference between them? What do most guys go with? I don't want to be able to see the factory grille behind the billet grille. Do you take the factory grille out with the over lay style? Thanks for your help guys.

 

With the overlay style it simply mounts in front of your factory grill. With the replacement style (if you have the honey comb style) you have to cut the honeycomb out buy leave the factory trim ring. Alot of guys go with the overlay style simply because its easier to install.
