Once they're more widely available, aftermarket air intake and exhaust.

I've venture to say about 20 - 40 hp. You should get better fuel economy with the exhaust and air intake ... that is as long as you're not even more tempted to crush the throttle with the newly discovered power. =)

I'm not really about the sound of the exhaust as much as I am a HP junkie.

Do you really need this truck any louder? I mean, I thought about it at first but this thing has a great sound when it is warmed up.
