FMIC.Pro valved cat-back exhaust system for BMW 4 Series G22 G23 420i 425i 430i 2.0T (2020-)

The FMIC.Pro cat-back exhaust system is designed to improve exhaust gas flow and provide a noticeably sportier sound.
The 76 mm (3.0") pipe diameter combined with the muffler configuration provides a deeper and fuller tone under load, while maintaining driving comfort during normal operation, especially with the valves closed.

The system is made entirely of SS304 stainless steel, which is resistant to corrosion and high operating temperatures. CNC mandrel-bent piping ensures uniform geometry and a precise fit to factory mounting points. Installation is simple and follows the plug & play concept. All welds are performed using TIG welding in an argon atmosphere, ensuring clean, aesthetic, and fully sealed joints, which are essential for long-term durability.

10 mm thick CNC-machined flanges are used at connection points. These provide high rigidity, reduce the risk of deformation caused by thermal cycling, and ensure uniform gasket pressure across the entire surface.

The system features integrated electronic exhaust valves that control exhaust gas flow in the rear section:

Closed mode: exhaust gases pass through the full muffling section, providing a refined sound and great comfort for daily driving.

Open mode: exhaust gases bypass the rear muffler, resulting in a louder, more direct, and sportier exhaust sound.

This solution allows the driver to adjust exhaust characteristics based on driving conditions and personal preferences. Valve control is handled via the included control module and two remote controls, allowing for instant mode switching.

For maximum performance, it is recommended to pair the FMIC.Pro exhaust system with a high-flow downpipe (especially for turbocharged engines).

Exhaust tips: 2x2 round. Pipe diameter: 76 mm / 3.0”.
Engine: 2.0T B48 B48B20 / B48TU1
