I just ordered Kook's LT headers for my 06 Mustang GT. I can't wait to hear the way the car will sound with my corsa mufflers. I have heard the way the car sounds on Utube but not In person. I had the choice between the H pipe or the X-pipe, and I went with the X-pipe. The next mod is the Super charger!!!!! Im looking at one of the Saleen kits. I currently have 4.10s in now but still have the 3.55's or should I get 3.73's?????? Does anyone have a twin screw supercharger with 4.10's?
