FMIC.Pro electronically controlled exhaust system for Porsche 911 Turbo 991.2 3.8L 2016–2020
The FMIC.Pro 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 system is made entirely of SS304 stainless steel, which resists corrosion and high operating temperatures. CNC-bent pipes ensure uniform pipe geometry and precise fitment to the vehicle's original mounting points. Installation is straightforward and based on a plug & play principle. All welding seams are TIG welded under argon gas shielding, ensuring clean, finished, and completely sealed joints – which are essential for the longevity of the system.
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 even compression pressure on the gasket across the entire mating surface.
The system features integrated electronically controlled exhaust valves that regulate exhaust gas flow through the rear of the system:
Valves closed – Exhaust gases pass through the entire muffler system, resulting in a subdued sound and excellent driving comfort for everyday driving.
Valves open – Exhaust gases bypass the rear muffler, resulting in a louder, more direct, and sportier exhaust sound.
Thanks to this solution, the driver can adjust the exhaust sound according to driving conditions and personal preferences. The valves are controlled by an included control unit and two remote controls, allowing for immediate switching between operating modes.
To achieve the best performance potential, it is recommended to use the FMIC.Pro system in conjunction with a high-flow downpipe, especially on turbocharged engines.
