Frequency Intelligent Valvetronic Exhaust System technology offers our cutting-edge intelligent ECU exhaust control valve, with an emphasis on the optimization of both acoustics and performance. It is a testament to our philosophy of the ultimate union of comfort and performance experience for the driver and passengers.

When the valves are fully open for maximum flow and power, it creates an exotic tone and allows for high performance. When the valves are closed, volume is reduced for a more low-profile comfortable drive. With our latest technology, just one click on the remote control will setup any rpm to automatic mode. The automatic mode enables the system to detect the engine RPM to intelligently switch comfort/racing exhaust profiles. Users can also opt to simply switch valve on/off mode as desired by remote control when driving.

Furthermore, the muffler internals are individually designed and fabricated for each car model, a perfect testament of our insistence on producing the best customized products in the market with our Valvetronic technology for ultimate performance. Each product has its own unique sound acoustics and performance, all to add the "extra" in extraordinary.

It is truly the perfect combination of comfort and performance that will give drivers more smiles per mile.

Valvetronic Technology

Valvetronic exhaust systems first appeared in the 1960s in Lamborghinis, Ferraris, and other high-performance sports cars. This new technology was used to control airflow, volume, and enhance a vehicle’s overall performance. It was, therefore, possible for sports cars to boast high torque power at low rev speeds and larger horsepower numbers at even higher rev speeds.

The FI Exhaust team applies this innovative technology in all its products, which provide Valvetronic capabilities to all vehicles – even those not originally designed with them.

Operating The Valvetronic System

FI Valvetronic Exhaust Systems offer intelligent ECU exhaust valve control and focus on optimizing both acoustics and performance. When the valves are fully open, flow and power are maximized, emitting an exotic note and delivering higher performance. When the valves are closed, the volume is reduced for a more comfortable and low-profile cruise. What’s more, just one click on the remote control will setup any rpm to automatic mode. This enables the system to detect the engine rpm and intelligently switch between racing and comfort exhaust modes. Drivers can also choose to simply switch the valves on and off mode with the remote control when operating the vehicle.
