Axleback exhaust systems generally include what's behind your rear axle. These are among the easiest of exhaust upgrades to install, and give you an instant upgrade in sound.
FITMENT NOTE: An extra stock valve actuator (BMW # 18308686640) is needed when installing the Slip-On exhaust system on BMW M240i (G42). Offering noticeable weight savings, increased power and torque, and a dramatic soundtrack, this system is constructed from lightweight high-grade titanium and completed with hand-crafted carbon-fiber tailpipes. Power and torque are increased by 7.1 Kw (9.7 hp) at 2,450 rpm and 20.5 Nm at 2,450 rpm when tested on the Akrapovič dyno against a BMW M240i with a standard stock exhaust. An exhilarating soundtrack is delivered through the use of special parts fitted into the system. Two valves – instead of one, as in the stock configuration – are calibrated to tailor the sound, and two acoustic reflectors are fitted on the tailpipes to guide the sound into the car’s cabin and change the driving experience, producing a fully immersive sound in the car’s cockpit, to supply thrills and enjoyment that can be enjoyed by all occupants. Because the Akrapovič Slip-On Line (Titanium) exhaust system has two valves, one more than the stock configuration, a TNG controller is included in the product to activate the additional exhaust valve. Two resonators, one on each side of the central muffler, perfect the sound experience.
