FI Exhaust - BMW G80 M3 G82 M4 S58 Titanium Signature 2021+ Valvetronic Exhaust


BMW G80 M3/G82 M4 3.0TT S58 Titanium Signature Series 2021+ FI Exhaust is a direct replacement bolt-on system developed out of an ultra-lightweight titanium material that on average reduces weight by 46% compared to stainless steel while retaining strength to weight ratio.

To achieve these incredible weight savings even the tiniest component of the BMW G80 M3 G82 M4 Titanium, e.g., valves, clamps, screws are made out of titanium.

Pipe walls are 1.6mm thick, which is 0.6mm thicker than other aftermarket exhaust options. The thickness improves exhaust sound frequency, increases durability and product lifespan. The extra weight is not significantly detrimental to performance. However, it increases safety for the drivers.

Pipes are also polished outside and inside to achieve aesthetic and performance benefits. The polishing process smoothes a titanium metal surface to remove imperfections such as nicks or scratches and improves exhaust gas flow and quality of the exhaust sound note.

The titanium exhaust for BMW G80 M3/G82 M4 3.0TT S58 is designed with a valvetronic technology to control airflow, sound volume and enhance the overall performance and torque. When valves are closed exhaust gasses are routed through the muffler resulting in a low-profile comfortable drive. However, when the valves are fully open an intense and exotic soundtrack is produced.

Switching between street and race sound profiles can be done using factory exhaust/sport button or drive mode, or optional FI Exhaust remote control and mobile App. The unique sound and performance are achieved through individually designed muffler internals that are fabricated for each car model to offer an ultimate driving experience.

Please note each part of the FI Exhaust system needs to be ordered separately.
Different exhaust parts are offered depending on the vehicle version.

Please note that the actual product may vary in appearance depending on the year of the car and area. The exhaust system is also subject to changes to the design over an extended time period. Product pictures are for illustration purposes only .
