Utilizing a single muffler arrangement, the fully titanium Akrapovič Slip-On is designed to be modular. In its basic mode, all exhaust gases flow through the muffler, giving you a deeper rumble of an exhaust note compared to stock without any drone. However, the muffler system is built in such a way that by replacing a blocking plate with the optional Akrapovic sound kit valve system the driver is able to noticeably increase the volume of the exhaust at the press of a button. Once activated, the majority of the exhaust gases route through the muffler bypass outlets. Even when installed on an otherwise stock vehicle, power gains are achieved, and weight reduction realized. Complete the look with a set of four exquisite tailpipes in titanium or carbon fiber.
