The system offers an 11.89 kg savings over the standard stock system, an incredible difference of 33%. Power and torque are increased by 3.4 Kw (4.6 hp) at 2,650 rpm and 12.4 Nm at 2,650 rpm when tested on the Akrapovi\u010d dyno against a BMW M440i with a standard stock exhaust. An exhilarating soundtrack is delivered through the use of special parts fitted in the system. <strong>Two valves<\/strong> \u2013 instead of one, as in the stock configuration \u2013 are calibrated to tailor the sound, and two acoustic reflectors are fitted on the tailpipes to guide the sound into the car\u2019s cabin and change the driving experience, producing a fully immersive sound in the car\u2019s cockpit, to supply thrills and enjoyment that can be enjoyed by all occupants. Because the Akrapovi\u010d 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. <strong>Two resonators<\/strong>, one on each side of the central muffler, perfect the sound experience. The smooth, rich sound at normal cruising rises to a deep and sporty soundtrack when driving more enthusiastically, and the tones can also be controlled from within the cockpit with addition of the optional Akrapovi\u010d Sound Kit. Special parts are cast in the Akrapovi\u010d in-house foundry to create the intricate and complex items needed for this system. It meets <strong>ECE type approval<\/strong>, and no remapping is needed for this configuration (the system only fits vehicles equipped with the OPF filter, and the ECE certificate is valid only for these cars; for non-OPF vehicles, an Evolution Line system is available). An optional link pipe set is available for those customers looking for an upgrade to the Slip-On Line (Titanium) exhaust system.<\/p>\n<p>Fitment notice: This product fits on the BMW M440i equipped with an OPF.<\/p>\n<p><strong>An extra stock valve actuator (part nr. 18 30 8 686 640) is needed when installing the Slip-On exhaust system on BMW M340i (G20, G21) and M440i (G22, G23, G26). <\/strong><\/p>\n<p>This product also fits on the BMW M440i xDrive Cabriolet (G23) model.<\/p>\n<p>The exhaust system fits on 2026 model year (engine type B58TU2), but the ECE type-approval certificate is not valid.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Offering a 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-fibre tailpipes.
