FMIC.Pro electronically controlled catback exhaust system – BMW X5 / X6 G05 / G06 40i B58 2018–
The FMIC.Pro catback exhaust system is designed to improve exhaust flow and deliver a distinctly sportier sound.
The 63 mm (2.5”) 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 original mounting points. Installation is straightforward and based on a plug & play principle. All welded seams are TIG welded under argon gas protection, ensuring clean, finished, and completely airtight joints – essential for long-term durability.
CNC-machined 10 mm thick flanges are used at the connection points. They provide high rigidity, reduce the risk of deformation caused by thermal cycles, and ensure uniform sealing pressure across the entire mating surface.
The exhaust system features integrated electronically controlled exhaust valves that regulate the exhaust gas path at the rear:
-
Valves closed: Exhaust gases flow through the entire muffler system, producing a subdued sound and good driving comfort for everyday use.
-
Valves open: 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 profile according to driving conditions and personal preferences. The exhaust valves are controlled by the included control unit and two remote controls, allowing for immediate switching between operating modes.
To maximize performance potential, the FMIC.Pro catback system is recommended for combination with a more free-flowing downpipe, especially in turbocharged engines.
The exhaust system is compatible with the original exhaust tips.
