Ditch the factory resonated mid section and replace it with two 3”, non-resonated mid-pipes designed to up the ante in the aggression department. Pairing the Performance Mid Pipes with the SwitchPath™ or Track Edition Exhausts will provide a deeper exhaust note with more volume (SwitchPath™ + Performance Mid Pipes is the best valve-closed soundtrack for this platform) and sharper sound effects when in Sport/Sport+ modes while keeping all factory emissions equipment in place. The Performance Mid Pipes install right behind the secondary catalysts (which come after the the factory downpipes).
