Competition Package Exhaust DIY?

Hi, I know the competition package comes with those wheels, a nice drop, and few other updates along with slight power increase, BUT with the exhaust as they claim the baffles are removed to give it a more sportier sound, is this not possible to get done yourself?

Kinda wondered as the wheels are growing on me! But for 7k how much can be done yourself and done better?
