1 . Is your exhasut cat-back? If so what diameter? If not, get a new one. Greddy is good.

2. Save your money and get an AEM Cold Air Intake. The K&N filters are good, but no replacement for a CAI.

3. NGK V-Powers. The splitfires will foul. There is no maybe. Not too mention you could buy 3 sets of NGK V-Powers for the price of one set of SplitFires.

You really need to figure out where you are headed. Do you want just the basic upgrades(intake, header, exhaust) for some power? Or do you plan on going turbo, nitrous or S/C? Do this and you won't spend money on stuff you don't need.
