FMIC.Pro valve-controlled catback exhaust system with single exhaust tips – BMW 5 Series G30 / G31 540i 3.0T 2017–2023
The FMIC.Pro catback exhaust system is designed to improve exhaust flow and produce a distinctly sportier sound.
The 76 mm (3.0”) pipe diameter combined with the muffler design produces a deeper and fuller sound under load while maintaining driving comfort during normal driving – especially when the exhaust valves are closed.
The exhaust system is made entirely of SS304 stainless steel, which resists corrosion and high operating temperatures. CNC-bent pipes ensure uniform geometry and precise fitment to the vehicle's original mounting points. Installation is straightforward and based on a plug & play principle. All weld seams are TIG welded under argon gas shielding, ensuring clean, finished, and completely airtight joints – these are essential factors for a long service life.
CNC-machined 10 mm thick flanges are used at the connection points. They increase the rigidity of the structure, reduce the risk of deformation caused by thermal cycles, and ensure even compression pressure on the gasket across the entire connection surface.
The system features integrated electric exhaust valves that control the flow of exhaust gases in the rear section of the exhaust system:
Closed position – exhaust gases pass through the entire muffler system, resulting in a subdued sound and maintaining high driving comfort for daily use.
Open position – exhaust gases bypass the rear muffler, resulting in a louder, more direct, and sportier sound.
Thanks to this solution, the driver can adjust the exhaust system's sound characteristics according to driving conditions and personal preferences. The valves are controlled by the included control unit and two remote controls, allowing the operating mode to be switched instantly.
To achieve the best performance potential, it is recommended to combine the FMIC.Pro catback exhaust system with a high-flow downpipe, especially on turbocharged engines.
