I really need to start getting better gas milage with the current prices, i'm not complaining about them, but i have already changed my foot, and got better fuel economy, is there anything under $200 that i could do to my gt to help get better fuel economy, i currently get the same as my cousin and thats 210 miles to a tank. Would something like mid pipes help alot? all i have right now is a K&N filter and flows
