Best bet is to start with an aftemarket performance air intake. (ex-K &N, AEM). Exhaust (flowmaster) is the next step. with those two you should an additional 15 ish horses. next step would a chip module. (ex-hypertech). Additional horses for you.

Intake will give you instant results. Throttle response, air flow, and a better sound
Exhaust. Will sound great. May not notice the performance portion, but needed.
Chip Module. Your biggest expense without getting in big, but will take your jeep to the next level. lets your jeep open up and remove rev limits and such. Fun to play with and works. Don't fall trap to knock offs. You find a whole lot junk like on ebay. Stick to the heavy hitters with this. (Jet/Hypertech to name a couple.)
Check out www.jegs.com to look at some performance parts. There a decent site with a lot to look at. Have fun.

    Before I forget. You do have a newer vehicle. Check with your dealer on warranty issue first. Exhaust shouldn't be an issue, but some won't stand by you if you modify your engine. Double check so you don't run into trouble.
