Mid Pipe + Valvetronic Muffler (Compatible with OEM Elect. Valve - No Remote Control Included)
Audi SQ8 Fi Exhaust (Frequency Intelligent Exhaust) high-performance valvetronic exhaust system is direct replacement bolt on system manufactured out of a high-grade T304 stainless steel that offers an exhilarating soundtrack.
The Audi SQ8 Fi EXHAUST system is designed with a valvetronic technology to control airflow, sound volume and enhance the overall performance and torque. On average horsepower is expected to increase from 5-10% after installing a full catless system, which includes a valvetronic catback and ultra-high flow downpipe.
When valves are closed exhaust gasses are routed through the muffler resulting in a low-profile comfortable drive. However, when the valves are fully open an intense and sporty soundtrack is produced.
Switching between street and race sound profiles can be done using factory exhaust/sport button or drive mode, or optional Fi EXHAUST remote control and mobile App.
The unique sound and performance for Audi SQ8 is achieved through individually designed muffler internals that are fabricated to offer an ultimate driving experience.
Please note each part of the Fi EXHAUST system needs to be ordered separately.
Different exhaust parts are offered depending on the vehicle version.
Please note that the actual product may vary in appearance depending on the year of the car and area. The exhaust system is also subject to changes to the design over an extended time period. Product pictures are for illustration purposes only.

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 Standard Version
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 ECU tuning.
Catless Sensor Version
The ultra-high flow catless downpipes remove restrictive factory catalytic convertor. They increase exhaust gas flow and performance gains, produce higher sound volume. The downpipe is also equipped with a dummy oxygen sensor to reduce a chance of the check engine light (CEL) being triggered.
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 EXHAUST 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.
The benefits of installing Fi exhaust catback system:
- Increased horsepower and torque: The cat-back exhaust system provides a vital boost to ensure the vehicle produces maximum horsepower and torque. The cat-back system has a larger diameter than a standard muffler; the wide opening creates more space for the free flow of air.
- Better fuel economy: Fuel economy is another notable benefit a vehicle acquires after the installation of a cat-back system.
- Unique sound: The Fi EXHAUST system is designed with a valvetronic technology to control airflow, sound volume and enhance the overall performance and torque. It can adjust the volume and tone of your exhaust according to your driving mode and speed.
