If you don't drive your GT, you don't need these, if you do drive it, you need them. I had mine shipped directly to Rich, he smoothed and painted them for me, they're a perfect match. Clips won't melt and snap off, the plastic won't warp, due to heat. I will say, you'll add about a pound or so in weight, but put on the GTGuys X-pipe, and you'll lose about 30 pounds net!!!
