Frequency Intelligent Valvetronic Exhaust System technology offers cutting-edge intelligent ECU exhaust control valve, with an emphasis on the optimization of both acoustics and performance. A user can expect from 5% to 10% horsepower increase without ECU tuning. Every exhaust system is carefully sound tuned and rigorously tested to a specific frequency with Fi EXHAUST intelligent controller to produce maximum optimized performance and comfort driving. Remote controller allows a user to switch between valves ON/OFF modes. When the valves are fully open for maximum flow and power, it creates an exotic tone and allows for high performance. And when the valves are closed, volume is reduced for a more low-profile comfortable drive. Furthermore, the automatic mode enables the system to detect the engine RPM to intelligently switch silent/sport exhaust profiles. Lastly, with upgraded remote controller users can control valves with a mobile APP, which is available both on Android and iOS. The APP also includes diagnostic tools which allow for a user to check and erase error codes.
