AKRAPOVIC S-BM/T/40H Exhaust System Slip-On Line (Titanium) for BMW M3 (G80 / G81) / M4 (G82 / G83) 2026-

Description AKRAPOVIC S-BM/T/40H Exhaust System Slip-On Line (Titanium) for BMW M3 (G80 / G81) / M4 (G82 / G83) 2026-

This high-grade lightweight titanium exhaust system, finished with hand-crafted carbon-fibre tailpipes, weighs 35% less than stock and features a pair of collectors cast in the in-house foundry. The Slip-On Line (Titanium) includes a specially developed Akrapovič control kit for a complete sound experience.

The sound character offers a rich tone during normal cruising, rising to a deep sporty sound when the M3/M4 is driven more dynamically. The tailpipes feature a ground-breaking octagonal shape made from lightweight titanium with a carbon-fibre outer sleeve. A classic cylindrical design is also available.

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 required for this configuration. It fits OPF and non-OPF vehicles, but the ECE certificate is valid only for vehicles equipped with OPF filters. Optional link pipes and Downpipes are available for closed-circuit use. An optional Akrapovič Sound Kit is also available. Installing the optional link pipes, Downpipes, or Akrapovič Sound Kit invalidates the ECE type approval of the Slip-On Line (Titanium).

An optional hand-crafted carbon-fibre rear diffuser is available to add further visual impact to the Akrapovič tailpipes.

The exhaust system also fits xDrive, CSL, CS, LCI, M3 Touring (G81), M4 (G83) Competition, and Convertible models. The ECE type-approval certificate is not valid for CSL and CS models. The Slip-On Line (Titanium) exhaust system is ECE type-approved for vehicles equipped with Otto/gasoline particulate filters. The certificate covers Euro 6 EC-compliant vehicles.

Important: The Tail Pipe Set (Carbon) must be ordered separately as a mandatory part. One of TP-CT/69, TP-CT/68, or TP-CT/73/CF must be selected.
