80mm mass air kit from geno (that will delete the air silencer also) Cats removed, third o2 sensor shut off, true duals with a custom made X-pipe, you won't be able to buy one that will fit under the car. and a dyno and tune. Maybe a 50 shot also. If you want to go big, throw in a port and polish also. Just a tune and maf will wake it up. You do everything that is listed here make sure your sitting on a extra $1200, just incase the trans gives up on ya.
