Buy or have a muffler shop build you a cat back system. If you are lucky you may pick up 5 hp.

As FOR is alluding to...save your wallet. Both the air intake AND exhaust are already oversized for the app, so no hp gains are to be had...especially at midrange. And you may lose some low end torque, which will piss you off.
