I've got a 1999 with a 5.4L and I've installed a K&N cold air intake, Gibson ceramic headers, and a custom, cat-back, true-dual 2 1/2 inch exhaust with magnaflow x-pipe and dual magnaflow mufflers. The truck runs great, sounds great and has great power and torque (the latter is more important to me). I'm looking into some more minor engine upgrades and was wondering what other people were running. I'd like to keep the mileage roughly the same and I live in California, so my upgrades have to be tree-hugging hippie approved.
