Akrapovic Slip-On Line titanium exhaust for the 2023-2025 BMW M240i (G42). Lightweight high-grade titanium construction with hand-crafted carbon-fiber tailpipes, dyno-tested at Akrapovic for gains of 9.7 hp and 20.5 Nm at 2,450 rpm over the stock exhaust. A two-valve design (versus one stock) with two acoustic reflectors tailors the sound, and an included TNG controller activates the extra valve. ECE type approved with no remapping required (ECE certificate valid only for OPF-equipped cars). An extra stock valve actuator (BMW part 18 30 8 686 640) is required for installation.
