            Awesome looking

            The carbon fiber quality is outstanding. The look is perfect for me. The install took me about 6 hours, this includes going to the store for some bolts for the reverse light, I was upset that this did not come with it. I had to grind down the 6 tabs to allow the clips to slide on properly. You would think, they would have done this at the factory. I installed the corsa quad tips and they fit fine. Thanks AM for free shipping!!! #Cajun Coyote
