The Akrapovic S-BM/T/34H Slip-On Line replaces the factory rear silencer on the 2023 to 2025 BMW M2 Coupe (G87) with a high-grade titanium assembly built for the S58 3.0L twin-turbo inline-six. Dyno testing confirms gains of +3.9 kW and +13.5 Nm at 2,800 rpm with a weight reduction of 7.3 kg, a 32.7% reduction from the OEM rear silencer. The S-BM/T/34H is compatible with both OPF and non-OPF G87 variants. ECE type approval is valid for OPF-equipped vehicles only; on non-OPF models this system is intended for off-road or competition use. The system ships without exhaust tips, which are sold separately, and the optional Akrapovic Sound Kit is available for wireless valve control. Bolt-on installation with no cutting or welding; estimated shop time is approximately 60 minutes.

Frequently Asked Questions
Does the Akrapovic S-BM/T/34H fit both the 2023 and 2024 to 2025 BMW M2 G87?Yes. The S-BM/T/34H is confirmed for all model years 2023 to 2025 of the BMW M2 Coupe (G87) equipped with the S58 3.0L twin-turbo inline-six. It fits both OPF and non-OPF G87 configurations without modification.
How much power does the S-BM/T/34H add to the BMW M2?Akrapovic's dyno results on the G87 show gains of +3.9 kW and +13.5 Nm at 2,800 rpm. This is meaningful on the S58 platform because the gains occur at a mid-range rpm that directly improves acceleration from rolling speed and track exit performance.
How much weight does the S-BM/T/34H remove?The S-BM/T/34H removes 7.3 kg from the rear of the G87, which represents a 32.7% reduction versus the factory rear silencer. The reduction in rear mass improves weight distribution and contributes to sharper steering response and corner entry stability.
Are tips included with the S-BM/T/34H?No. The S-BM/T/34H ships without exhaust tips. The Akrapovic carbon fiber tail pipe set TP-BM/34H is sold separately and available in octagonal or cylindrical configurations. Contact Black Ops Auto Works to add the correct tip set to your order.
Is the Akrapovic S-BM/T/34H street-legal on the BMW M2 G87?The S-BM/T/34H holds ECE type approval for G87 BMW M2 models equipped with the OPF (Otto Particulate Filter). On non-OPF G87 variants, this system is intended for off-road and competition use only. Confirm your vehicle's OPF status with your BMW dealer before ordering if street legality is a requirement.
What is the Akrapovic Sound Kit and is it required?The Akrapovic Sound Kit is an optional accessory that allows wireless control of the dual exhaust valves on the S-BM/T/34H. It is not required for installation or operation; the valves function automatically based on driving mode and RPM without it. The Sound Kit is sold separately and simply adds wireless override capability.
What does the BMW M2 G87 sound like with the Akrapovic S-BM/T/34H?The S-BM/T/34H delivers a deep, resonant tone from the S58 inline-six that is refined and controlled at low throttle and during highway cruising, with no cabin drone. Under hard acceleration the exhaust opens into a sharper, more aggressive note through the rev range that is substantially more characterful than the factory system.
What is the warranty on the Akrapovic S-BM/T/34H?Akrapovic covers the S-BM/T/34H with a limited lifetime warranty against defects in manufacturing. This applies under normal street and occasional track use conditions. Contact Black Ops Auto Works for full warranty registration instructions.
