Installation of the exhaust system:

Exhaust system components:
This exhaust system package includes the following components:

• Catless Downpipe

Please note that if the exhaust comes with a standard remote control and you decide to upgrade to the Fi Pro remote control, the standard remote control will no longer be included in the shipment.

Made from the highest quality T304 stainless steel, this direct bolt-on system provides an exciting soundtrack that complements the dynamic capabilities of the BMW G80 M3 / G82 M4.

Equipped with Valvetronic technology, the Fi BMW G80 M3/G82 M4 exhaust system allows precise control over airflow, sound volume and overall performance, increasing both power and torque.

With a full catless system, including a valvetronic catback and ultra-high-flow downpipe, you can expect a power gain of 5-10% on average. 

When driving with a low profile, the closed valves direct exhaust gases through the muffler for a comfortable ride. However, when the valves are fully open, the system unleashes an intense and sporty soundtrack, enhancing the driving experience.

Switching between street and race modes is seamless, whether using the factory exhaust/sport buttons, driving modes or the Fi Pro remote control upgrade.

Availability may vary depending on vehicle model and exhaust system configuration; please refer to the add-ons section and consult with our representative to confirm.

Behind the exceptional sound and performance are meticulously designed muffler internals, tailored to provide an unparalleled driving experience specifically for this car model.
