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.

"With the valves closed and the car being revved, the new Fi exhaust produces 119 dB, significantly louder than the 97.8 dB of the standard exhaust at idle. With the valves opened and the car revved, it produces just in excess of 131 dB. To put that into perspective, it’s roughly the same amount of sound produced by a jackhammer.

Driven on the street, the exhaust produces a truly epic cacophony of noise and crackles and pops on the overrun. As awesome as the exhaust sounds in this video, we imagine it sounds even better in person." -
