FI Valvetronic Exhaust System for BMW X5M F85/ X6M F86

The BMW F85 X5M Fi Exhaust (Frequency Intelligent Exhaust) system is a high-grade T304 stainless steel, direct-fit valvetronic exhaust designed to enhance performance and torque while providing an exhilarating soundtrack. When the valves are closed, exhaust gas is routed through the muffler to reduce noise levels, but when the valves are open, for a sporty and intense sound. On average, installing a full catless system (valvetronic catback and ultra-high flow downpipe) can increase horsepower by 5-10%. Switching between street and race sound profiles can be done through factory or optional Fi EXHAUST remote control or mobile App. For unique sound and performance, the muffler internals are individually designed. Please note each part of the system has to be ordered separately and the actual product may vary in appearance depending on the vehicle and area. Product pictures are for illustration only.
