Fi 2019-2025 BMW G01 X3/G02 X4 M40i | 3.0T B58 | Valvetronic Catback Exhaust

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

• Front Pipe + Mid Pipe + Valvetronic Muffler (Retains OEM Valve Settings – No Remote)

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

Crafted from premium T304 stainless steel, this direct bolt-on system delivers an exhilarating soundtrack that complements the BMW G01 X3/G02 X4 M40i dynamic capabilities.

Equipped with valvetronic technology, the Fi BMW G01 X3/G02 X4 M40i exhaust system allows precise control over airflow, sound volume, and overall performance, enhancing both power and torque.

With a full catless system, including a valvetronic catback and ultra-high flow downpipe, horsepower gains of 5-10% can be expected on average.

During low-profile cruising, the closed valves channel exhaust gases through the muffler, ensuring a comfortable ride. However, with the valves fully open, the system unleashes an intense and sporty soundtrack, amplifying the driving experience.

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

Availability may vary depending on your car model and exhaust setup; please refer to the add-on section and consult our representative for confirmation.

Behind the unique sound and performance lies meticulously designed muffler internals, tailored to deliver an unparalleled driving experience specifically for this car model.
