Replace resonator with straight pipe... cut off mufflers and replace with straight pipe... its not the best setup but its the cheapest route. It sounds louder, but drones on highway. It was my first setup and was nice for a little while, until the droning got old. If you can go with True Duals, then do it... you will love it.
