You'll get noise, but no grunt. You can't even feel 2-5 hp with the butt dyno. For the na PT an exhaust will give you a cooler sound, but no hp gain. An intake will also give you a cooler sound, but again, no hp gain you'll feel. In fact, a hot air intake will cost you both hp and torque so get one like the Airaid or the Volant as they at least try to keep the hot air out and do a pretty good job of it.
