I was wondering is there to install fog lights on the grill how gts have them on a v6??
0) You need a GT grille with the fog lights (duh).
1) You need a front bumper cover that's compatible with the GT grille. Any of the V8 bumper covers (GT/CS, GT, etc), and most/all of the aftermarket bumper covers should work.
2) If you don't get a take-off bumper cover that's already the right color, or if you buy a new one, you're going to have to paint it.
3) You need to modify your wiring harness. The absolute best and least hassle option here is the Starkey wiring harness ($190). It includes a pre-made harness and a new headlight switch. It takes about an hour to install.
All totaled, you're looking at right around $1000 if you need to paint the bumper cover.
As an alternative, you can buy a kit from Starkey that puts fog lights in the factory V6 bumper cover, and it includes the wiring harness and headlight switch. That kit will cost less than half what it would cost to install a GT grille.
A lot of folks with V6's installed the GT grille (or the center-mount grille) because they want the fog lights. Don't let the ass hats dissuade you from going the way you want to go. It's your car, not theirs.
