The latest addition to the BMW M series is the awe-inspiring M3/M4, an exquisite high-performance car that can be made even better by adding an Akrapovič Slip-On exhaust system. Made from titanium—with some parts cast in Akrapovič’s own foundry—it has bigger pipes than the stock exhaust, yielding lower back pressure and more power, especially at lower RPMs. This system is a completely new design, and it will reduce overall vehicle weight and deliver extra power and a sporty sound, which has been tailored to highlight lower frequencies and increase the listening enjoyment. Increases in both power and torque add to the sensory experience, combined with improved agility. The look of the Slip-On system can also be further enhanced by adding titanium or carbon- tailpipes and the stunning carbon- rear diffuser.An optional Akrapovič Sound Kit is available to control the different sound settings.Fitment notice: Exhaust system also fits to M3/M4 CS (Sport Club) version.
