BMW G8x M3/M4 (Competition) Fi Exhaust (Frequency Intelligent Exhaust) high-performance valvetronic exhaust system is direct replacement bolt on system manufactured out of a high-grade T304 stainless steel that offers an exhilarating soundtrack.

The Fi EXHAUST system is designed with a valvetronic technology to control airflow, sound volume and enhance the overall performance and torque. On average horsepower is expected to increase 5-10% after installing a full catless system, which includes a valvetronic catback and ultra-high flow downpipe.

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 sporty soundtrack is produced.

Switching between street and race sound profiles can be done using factory exhaust/sport button or drive mode.

The unique sound and performance for BMW G80 M3 / Competition is achieved through individually designed muffler internals that are fabricated 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.

No more neck pain
Size: Queen(Pack of 2)
I needed new pillows and I’ll be the first to admit that I’m picky about my pillow. I had ordered different ones to try and these were the keepers. They are not too soft nor too firm. I wake up with neck pain and headaches if I don’t have a good pillow. I’m not experiencing any either one now. Make the purchase for yourself and try them.
