This high-performance exhaust system, constructed entirely from lightweight titanium, was engineered for models with gasoline particulate filters and is fully EC/ECE type approved.

Product Information – Akrapovic BMW M5 (G90, G99) OPF/GPF Slip-On Line S-BM/T/37H
Developed to replace the stock system, the Akrapovič Slip-On Line provides a significant weight reduction of 31.8% (6.12 kg). Featuring cast titanium valve housings and bespoke collectors, this system has been engineered in-house to deliver a balance of elegance and aggression. Its larger-diameter exhaust tubes optimize airflow, while a special control kit adjusts the valve settings to tailor the exhaust sound across various driving modes—from refined and subtle to exhilaratingly sporty.
Dyno-tested, this system produced a power increase of 5.2 kW (7.1 hp) at 2,050 rpm and a torque gain of 24.3 Nm at 2,050 rpm, giving you faster throttle response and stronger acceleration.
This exhaust is a plug-and-play installation and requires no ECU remapping. However, it does require cutting the stock exhaust—detailed instructions are included to ensure proper installation.
Note: The Slip-On Line must be completed with a mandatory Tail Pipe Set (Carbon) in either hexagonal (TP-CT/79) or round (TP-CT/78) form. Both designs feature integrated acoustic reflectors to project part of the exhaust note back into the cabin for an immersive sound experience.
