The Akrapovic S-BM/T/2H Evolution Line Cat-Back Exhaust transforms the 2018-2020 BMW M5 F90 with a full titanium system that adds 12 hp and 24 Nm of torque while eliminating 10.8 kg of exhaust weight. Akrapovic S-BM/T/2H fits all F90 variants including the standard M5, Competition, and limited Edition 35 Years, connecting directly to the factory catalytic converters with no cutting or welding required. The hexagonal titanium mufflers preserve the OEM valve system for driver-controlled sound across M modes, and the S-BM/T/2H is backed by a 2-year Akrapovic warranty. Tips are sold separately for full customization. Every S-BM/T/2H is hand-TIG-welded at Akrapovic's Slovenia factory using the same aerospace titanium alloys as their MotoGP and WSBK race exhausts.

Installation Instructions
- Safely raise and support the M5 F90 on a lift or jack stands. Allow all exhaust components to cool fully before beginning work.
- Disconnect the factory exhaust valve actuator wiring connectors from the OEM rear mufflers.
- Remove the factory cat-back section by loosening the mid-pipe clamps and sliding the mufflers off the OEM rubber hangers.
- Retain all OEM rubber hangers; they will be reused to mount the S-BM/T/2H system.
- Dry-fit the Akrapovic front link pipes to the factory mid-pipe outlets and confirm alignment before tightening.
- Hang both hexagonal muffler canisters from the OEM rubber hanger brackets and seat them onto the link pipe inlets.
- Leave all clamp connections loose during initial fitment to allow tip opening alignment adjustment.
- Reconnect the factory valve actuator wiring to the S-BM/T/2H valve assemblies; connections are directionally keyed and cannot be reversed.
- Verify all components clear the underbody, heat shields, and rear diffuser by a minimum of 10 mm on all sides.
