FMIC.Pro valve controlled exhaust Mercedes-Benz A35 AMG 4MATIC W177 2018–2023
The FMIC.Pro exhaust system is designed to improve exhaust flow and deliver a distinctly sportier sound.
The 70 mm (2.75”) pipe diameter combined with the muffler design produces a deeper and fuller sound under load while maintaining ride 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 follows the plug & play principle. All joints are TIG welded under argon gas protection, ensuring clean, finished, and fully sealed weld seams – this is essential for long-term durability.
CNC-machined 10 mm thick flanges are used at the connection points. They increase structural 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 of the system:
Valves closed – exhaust gases flow through the entire muffler system, producing a refined sound and good ride comfort for daily driving.
Valves open – exhaust gases bypass the rear muffler, making the exhaust sound louder, more direct, and sportier.
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 for immediate switching between modes.
To achieve maximum flow and high exhaust system efficiency, the FMIC.Pro series includes a high-flow downpipe. After installation, the response of the lower engine torque range improves significantly, the turbocharger spools up faster, turbo lag is reduced, and the engine produces power and torque more effectively across the entire rev range.
