Product Description

Valve

All Fi EXHAUST exhaust systems are equipped with valvetronic technology. This technology is not only used to control sound volume, but also enhance overall performance of the vehicle. Before the inception of this technology, horsepower and torque were irreconcilable contradictions in the design of exhaust systems. This allowed sports cars to have high torque power at low rev speeds and even higher horsepower capability at high rev speeds.

Catless

The ultra-high flow catless downpipes remove restrictive factory catalytic convertor. They increase exhaust gas flow and performance gains, produce higher sound volume. And is usually recommended option going further with tuning. The downpipe is also equipped with a dummy oxygen sensor to reduce a change of the check engine light (CEL).

Sport 200Cell

With the larger cells and fast exhaust flow rate, it is smooth, durable and do not have refractory wool burn-out problems. The higher the number of the cells, the smaller and denser the hole is. The higher the back pressure, the more it can enhance torque performance, while the opposite is true for increasing horsepower.Converting your stock catalyst converter (400~800 CPSI) into our metallic catalyst converters will result in significant enhancements in airflow discharge that circumvents the limitations and parameters set by car manufacturers.

Fi EXHAST Pro Control System

Fi EXHAUST Pro Control System control system consist of intelligent control box, sporty 2 button style remote control and mobile App.

*The mobile App scans and deletes CEL using manual or Auto scan on the engine startup.

* Monitor real-time valve status with Fi EXHAUST Pro App’s intuitive and friendly interface.
* Assign Auto Mode data values. Afterwards the system will intelligently detect engine RPM/Speed/Turbo Boost and turn on the valves.

* Each remote control button can be assigned with 1 function to open/close the valves or activate Auto Mode delivering more precision in the hands of the driver.

* The design is smooth and offers a nice grip, and the aluminum alloy ring can be customized in 14 different colors or switched to forged carbon with a unique marble like texture.

Compatibility with OEM sport button/mode.

The intelligent valve functionality can be controlled using OEM sport button/mode to switch between valves ON/OFF and regulate desired sound volume. FI EXHAUST remote control is not needed and is an optional upgrade to have more control over exhaust valve behavior.

Ceramic Coating

Fi EXHAUST eliminates traditional thermal insulation materials that contain toxic substances, and directly coats the exhaust pipe with a nano-ceramic coating to protect from corrosion, reduce heat exposure to heat sensitive components in the engine bay and keeps temperature low. It’s a great way to improve longevity of the exhaust and other components prone to thermal degradation like wiring.

NON-OPF / OPF

OPF is also known as particulate filter or GPF gasoline particulate filter. In recent years, new car models will be equipped with this filter on the exhaust system in order to comply with increasingly stringent environmental regulations. Fi EXHAUST versions will also be developed on OPF and non-OPF vehicles to make sure fitment is precise.
