Akrapovič’s high-grade titanium construction was developed in-house and provides this SlipOn Line exhaust system a durable structure and finish, as well as a 32.7% weight savings over stock, according to the manufacturer, and uses two valves and two acoustic reflectors to tailor the sound. An ECU remap is not needed for the manufacturer-estimated, additional 5.2 hp at 2,800 rpm and 10 lb-ft boost in torque at 2,800 rpm. A separately sold exhaust tip set is mandatory, and two options are available – both constructed of titanium and carbon fiber for reduced weight and appearance. One set is rounded, and the other features Akrapovič’s octagonal shape.
For those looking for further weight savings and customization, Akrapovič has developed rear diffusers crafted using carbon fiber, available in matte or gloss finishes, the company said. An optional Sound Kit is also available which allows the driver to actuate the exhaust valves independently from the M2’s driving modes.
