Akrapovič BMW M3/M4 (F80/F82/F83) 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 F80 M3 and F82/F83 M4, built around the platform's twin-turbo S55 engine. 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 these cars genuinely deserve, how they 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 aggressive growl under acceleration, addressing the somewhat flat, turbocharged character many owners find the factory exhaust leaves on the table. 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 cars where reducing mass toward the rear axle has a measurable effect on handling balance and agility, exactly the areas enthusiasts on this platform care most about. The system is finished with your choice of hand-crafted tailpipes, both in a round design, giving you a genuine material choice depending on your priorities.

Please select your tailpipe style at checkout: Round Tail Pipe Set in Carbon, or Round Tail Pipe Set in Titanium, both included as part of this purchase at the same price.

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, and a matching carbon fibre rear diffuser for a complete visual package. Installing the Link Pipe or Sound Kit will invalidate ECE type approval for the system as a whole.
