The Akrapovic BMW M3 (G80, G81) OPF/GPF Slip-On Line S-BM/TI/33H merges lightweight titanium craftsmanship with superior power and a captivating exhaust note. Engineered to reduce overall weight by 35% compared to the stock system, it helps elevate your M3’s agility during cornering and improves responsiveness in every driving scenario.

Performance Gains with the Akrapovic BMW M3 (G80, G81) OPF/GPF Slip-On Line S-BM/TI/33H

On the Akrapovič dyno, the Akrapovic BMW M3 (G80, G81) OPF/GPF Slip-On Line S-BM/TI/33H delivered a power increase of 8.0 kW (up to 10.9 hp) at 6,000 rpm and a torque gain of 13.9 Nm at 5,000 rpm, measured against a stock M4 Competition exhaust. This improvement translates into stronger midrange thrust and an even livelier feel on twisty roads. Additionally, the weight reduction of 8.3 kilograms sharpens handling while preserving the iconic stability and precision of the M3 chassis.

Sound and Tailpipe Design

Two distinct tailpipe styles—featuring a distinctive octagonal or a more classic cylindrical shape—are available, although you must select one of the mandatory Tail Pipe Set (Carbon) options (e.g., TP-CT/69, TP-CT/68, or TP-CT/73/CF) when ordering this Slip-On Line. These hand-crafted carbon-fibre pieces highlight the titanium interior, creating a luxurious motorsport accent that complements the M3’s design.

The exhaust note reflects Akrapovič’s dedication to balanced acoustics. At lower revs, the tone remains civilized for everyday driving, but it morphs into a deep, sporty roar under enthusiastic throttle. This synergy delivers both comfort and aggressiveness. Meanwhile, the included control kit manages valve operation to refine the exhaust intensity at various engine speeds.

ECE Approval, Optional Parts, and Installation

For cars fitted with OPF/GPF, the Akrapovic BMW M3 (G80, G81) OPF/GPF Slip-On Line S-BM/TI/33H meets ECE type-approval requirements—no engine remap is necessary. If you wish to further explore closed-circuit modifications, optional link pipes and downpipes are available, but using these removes ECE certification. Similarly, installing the optional Akrapovič Sound Kit (P-HF1384) grants you adjustable volume settings yet also negates ECE approval. Because it’s a plug-and-play solution, expect installation to take about 240 minutes with standard workshop tools.

Moreover, for drivers who desire extra aesthetics, optional carbon-fibre accessories—like mirror caps or a rear diffuser—offer visual upgrades to match this exhaust’s performance orientation. These subtle yet effective enhancements help unify the car’s sporty persona from every angle.
