Akrapovic Slip-On Line Titanium Exhaust - BMW M240i (G42) B58

OVERVIEW

Offering noticeable weight savings, increased power and torque, and a dramatic soundtrack, this titanium slip-on rear exhaust for the B58-powered BMW M240i (G42) 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) and 20.5 Nm at 2,450 rpm on the Akrapovič dyno against a standard stock exhaust, with a 4.0 kg weight saving.

Two valves — instead of one, as in the stock configuration — are calibrated to tailor the sound, and two acoustic reflectors fitted on the tailpipes guide the sound into the cabin for a fully immersive experience.
