Fi Exhaust Valvetronic Exhaust System for G2x BMW 420i

Fi Exhaust G22 420i system is a direct bolt-on valvetronic exhaust for the BMW G22, G23, and G26 420i and its B48 turbocharged inline-four, built from high-grade T304 stainless steel and offered in dual-tip or quad-tip versions. Advanced valvetronic technology optimizes airflow, regulates sound volume, and improves torque; a full setup, including a valvetronic catback and ultra-high-flow downpipe, can increase horsepower by approximately 5-10%. With the valves closed, exhaust gases route through the muffler for a refined and comfortable driving experience; fully open valves produce an intense and sporty exhaust note. Meticulously designed muffler internals deliver a distinct sound tailored to the 420i.

Valve

Fi Exhaust systems universally incorporate valvetronic technology, enabling precise sound control while boosting vehicle performance. Prior to this innovation, achieving both high torque at low RPMs and greater horsepower at high RPMs was challenging. Valvetronic technology resolves this contradiction, allowing sports cars to excel in both areas and delivering a balanced yet dynamic exhaust performance.

Fi Exhaust Pro Control System

The Fi Exhaust Pro Control System includes an intelligent control box, a two-button remote, and a mobile app. The app prevents check engine lights, monitors valve status, and enables Auto Mode based on RPM, speed, or boost. The remote allows precise valve control, with a customizable aluminum or forged carbon design.
