Tune and intercooler seem to be at the top of the list for the best bang for the buck if you are looking at performance mods. Tons of post on here to search through for those topics so ill leave that to you. I prioritized the exhaust as well as while its not really a performance gain, the sound and the looks were worth it to me. Suspension is another area where you can make a difference without a huge amount of spend. The Steeda subframe bushing support kit and their vertical link pieces seem to be favorites along with rear roll bars and lowering springs. Also, it might be worth your time to look at diff bracing if you plan to head down the performance rabbit hole (1 bolt vs 2 bolt set-up). Welcome to the forum!
