The SwitchPath Catback Exhaust for the F80 M3/M4 from AWE offers a perfectly balanced and tuned exhaust that will deliver power when needed without droning at cruising speeds. By replacing the factory muffler, you will uncover the pure sound of the S55 engine. This exhaust is perfect for those who want a more aggressive response when getting on the throttle, but don't want to wake up the neighbors. The SwitchPath™ Technology utilizes factory valving and M-Sport button to adjust tone on the fly.
