Then no headers for you. Don't get the throttle body spacer, it does jack shit and just "whirrs." I don't know about intakes, the norm seems to be the K&N CAI but they are all on about the same playing field, you could just save yourself some bucks and drop in a K&N and remove the intake resonators and go along on your merry way. Truthfully its what you want to do with the truck, use your creative eye, or ear or whatever and get to it. Just remember to not cheap out on the exhaust, rust is not your friend.
