Akrapovič BMW M240i (G42) Slip-On Line Titanium Exhaust System

The Akrapovič Slip-On Line (Titanium) is a precision-engineered exhaust system that brings out the true character and performance of the current-generation BMW M240i G42. Crafted entirely from lightweight titanium, this system is designed to enhance every aspect of the driving experience, from sound and performance to weight savings and aesthetics. More than just an exhaust, it's the finishing touch this genuinely capable performance coupe deserves, how it should have come from the factory.

The Slip-On Line transforms the exhaust note entirely, delivering a smooth, refined tone at cruising speeds that opens up into a genuinely deeper, more purposeful growl under acceleration. Akrapovič's engineers retained the factory dual-mode, ECU-controlled valve from the original system, letting you switch seamlessly between a civilised, comfortable character for daily driving and a genuinely sportier, more aggressive note when you want it, all without any unwanted drone creeping in during either mode. Complex components, including the valve housings and collectors, are cast in Akrapovič's own in-house titanium foundry, a level of manufacturing precision that's difficult to replicate with off-the-shelf mandrel-bent pipework.

As the successor to the F22 M240i, the G42 arrived with a genuinely more grown-up factory exhaust tune, but one that still leaves real room for a more characterful note once you're pushing the car harder. Titanium construction delivers a genuine weight saving over the factory steel exhaust, a real benefit for a rear-wheel-drive coupe where reducing mass toward the rear has a measurable effect on handling balance and agility. The system is finished with hand-crafted carbon-fibre tailpipes, included as standard, giving the rear of the G42 a distinctive, purposeful look that signals exactly what's fitted underneath.

Important installation note: fitting this system requires the stock exhaust to be cut, this is not a reversible bolt-on modification. Review Akrapovič's installation instructions carefully before starting, and if you're not confident doing this yourself, have it fitted by a workshop experienced with Akrapovič products.

Optional upgrade available: Akrapovič's Sound Kit is available for this platform, letting you control the exhaust valves independently of the car's drive mode via a dedicated remote or smartphone app. Installing this optional upgrade will invalidate ECE type approval for the system as a whole.
