I got my headers on 9-03. Hope I didnt already post this? But I bought the 14guage triple nickle chrome headers from Thorley. I got them put on and man, Talk about a deffinent increase in HP! I think they were deffinently worth the money. For all ya 4x4's out there that have a t-bar lift or so, your gonna have to get the y-pipe to these headers modified,,,,, sucks, I had to do that cuz my driveshaft to the 4WD kept hitting the new crossover pipe. On a stock HB with these headers, they told me there was a 3" clearance between the driveshaft and the pipe, I had about 1/8" clearance. Now I got 2" cuz I modified it. Im gonna get pics soon.
