Akrapovič Slip-On Line Titanium Exhaust System - G8x M3, M4

A pioneer in its field, Akrapovic is widely recognised as a highly innovative materials technology company. The brand is synonymous with the highest level of design, performance enhancement and the creation of an unmistakable deeply resonant exhaust sound and style.

Product Information

Introducing the all-new Akrapovic Slip-On Line Titanium Exhaust System for the latest generation G80 M3 Sedan, G82 M4 Coupe and G83 M4 Convertible.

This high-grade lightweight titanium system, finished with hand-crafted carbon-fibre tailpipes, weighs in at 35% lighter than stock and features a pair of collectors cast in the in-house Akrapovič foundry. The Slip-On Line (Titanium) comes with a specially developed Akrapovič control kit for a complete sound experience. The sound character offers a rich tone at normal cruising, rising to a deep sporty sound when the M3/M4 is driven more dynamically. It serves up a perfect sound at all rpms, delivering comfort and sportiness in one exhaust. A ground-breaking octagonal shape has been fashioned from lightweight titanium with a carbon-fibre outer sleeve for the tailpipes, and for more traditional buyers there is the classic cylindrical design.

The system delivers power increases of 8.0 kW (10.9 hp) at 6,000 rpm and a torque gain of 13.9 Nm at 5,000 rpm when tested on the Akrapovič dyno against a BMW M4 Competition with a standard stock exhaust. Remapping is not needed for this configuration, and it fits all vehicles (OPF and non-OPF), but the ECE certificate is valid only for cars equipped with an OPF filter.

An optional Evolution Line Titanium Link Pipe Set, Downpipe Set with Cats or Downpipe Set without Cats are available for customers looking for a cat back or turbocharger back exhaust system upgrade. The Akrapovič Sound Kit is also available. With the installation of the optional link pipes, downpipes, and Akrapovič Sound Kit, ECE type approval of the Slip-On Line (Titanium) is no longer valid. An optional hand-crafted High Gloss Carbon Rear Diffuser is also available to add an extra visual impact to the Akrapovič tailpipes.

The exhaust system also fits xDrive models.

Sean arranged a Quaife LSD for my 135i and I couldn't be happier. He advised multiple seals and bearings needed replacing unbeknownst to me so these were done as well. Now I have a more reliable car and one with tonnes more mechanical grip!

Excellent service at reasonable prices. The shop is very nice too, you almost feel like you're at BMW.

Took my e60 there, Jimmy was an absolute pleasure to deal with, very honest, explained everything in detail, and provided some great recommendations due to my individual circumstance. Can not recommend highly enough.
