I just finished my first round of mods on my 2013 Longhorn. I fell in love with this truck at the Dallas Auto Show and in a weird twist of fate ended up buying the exact truck that was on the floor (my kids like that story anyway). So far I put on a Vararam Air Grabber, Moe's ported 87mm TB, XLerator 22" muffler, Daystar 2.5" level & lift, and a Bakflip F1 tonneau cover. I joined this forum and rad many posts before I made any mods so I wanted to say thanks and show you what all of you helped me come up with. Tires are next but I have a hard time ditching perfectly good ones..........for now.
