Akrapovič BMW M240I (F22/F23) 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 BMW M240i, available for both the F22 coupe and F23 convertible body styles. 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 underrated 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.

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, particularly relevant on the F23 convertible where the added weight of the folding roof mechanism makes every other kilogram saved elsewhere in the car that bit more meaningful. The system is finished with hand-crafted carbon-fibre tailpipes, included as standard.

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 upgrades available: Akrapovič also offers a matching Evolution Link Pipe Set for this platform, which further deepens the exhaust note and adds additional weight savings when combined with this Slip-On Line, alongside an optional Sound Kit that lets you control the exhaust valves independently of the car's drive mode. Installing either of these optional upgrades will invalidate ECE type approval for the system as a whole.
