While this upgrade won’t deliver the full benefits of a complete performance exhaust system, it removes the factory resonator designed to mute your exhaust. By deleting the resonator, you’ll enjoy a more aggressive sound, a slight reduction in weight, and potential performance gains. (Fits the OEM back box and/or rear section only.)
