Akrapovic BMW M5 (G90) Evolution Catback Exhaust - Titanium 2025-2027

Part S-BM/T/38 is the Akrapovič BMW M5 (G90) Evolution Catback Exhaust - Titanium, an Evolution Line exhaust made for the BMW M5 (G90). On the Akrapovič dyno it added 11.4 hp and 11.5 lb-ft.

Performance and Sound

An Evolution Line covers a longer stretch of the exhaust than a slip-on, usually from the catalytic converters or the middle section back. The bigger scope lets Akrapovič tune the whole flow path for power, torque and sound together. The valved design means one exhaust can be refined on the motorway and loud on a back road or track. Akrapovič notes that no ECU remap is needed for this setup. Akrapovič also offers optional link pipes for this car, intended for closed-course use. Akrapovič has versions and fitment notes for cars with and without a particulate filter, so check the engine and chassis in the table.

Materials and Construction

The titanium construction saves weight compared with the steel factory parts. Titanium also handles high exhaust temperatures and takes on its distinctive colouring with use. Some of the parts are cast in Akrapovič's own titanium foundry.

Akrapovič designs and builds its exhausts in Slovenia. The company is known for its titanium work, its carbon-fibre parts and the sound tuning it does for each car.
