wouldnt you technically be losing power with an exhaust and no intake. Wont that be pushing more air out than its sucking in???

Hey, Houston T, what part of town do you live in. I live in Pearland. I have had my Matador Red Metallic F since March 3rd and have only seen one other here in the city. I drive it to Park 10 (just west of Hwy 6 one I-10) almost every day. Drive around Beltway 8. Love my F.
