Technically, stage 2 doesn't require either hard part but you will not be garnering the advertised gains without them. In reality the exhaust only contributes a slight bit of power at the top end of the power but nothing that is really noteworthy. The exhaust for all intents and purposes is a sound only upgrade. The intake and stage 2 are where you are getting the power from although again you could run stage 2 without the intake and you would still get a minimal gain from over stage 1 due to a slight boost increase in the stage. You will be running slightly richer however as the stage 2 tune is expecting more air from the revised intake that isnt there. The intake also helps with drivability as the throttle response is improved.

Since it will be the next question....Without the intake and just stage 2 you may get another ~5-7 HP over stage 1 (peak).
