I'm wanting to upgrade the performance of my 2009 5.4L. I've done the air intake, throttle body spacer, and bigger throttle body. I plan on getting an Edge programmer, headers and exhaust. I wanting to know if there is anybody makes an off road Y or X pipe for my truck? I have found some other bolt ons like coil packs and mass air meter. I was also wanting to know if there is anything else out there and where I could find it? I heard about an intake, but haven't found anything yet. Please help me!
