I would start with a air intake, throttle body, headers, and exhaust. I tiend to stick with BBK performance but hey, thats just me. 3.73 gears will make a huge difference for you, or if u mainly drive it on the track put some 4.10 gears in it, but u wont get good gas mileage with the 4.10s but a big takeoff difference. Hope I helped some. PIECE!!!
