Welcome to the forum and post some pics of your car! And you already have one of the three low budget or minor mods down with the CAI so you pretty much have cat-backs/mufflers and tuners as your other two mods, everything else starts costing significantly more beyond those at least performance wise. You have your front lip spoilers from Mopar and Danko as visual exterior mods, the Mopar one is about 100-120, not sure about the Danko one. You could also get a different shifter, Mopar makes one (which I just ordered with their front lip spoiler as well but for the gen 2 car). That's just the basic stuff, you can type "mods" on the search bar and a ton of stuff will come up.
Good luck and have fun. :beerchug:
