Also features four preset positions which is Closed, 25%, 50%, 75%, Open. ● Matrix Mode: Set vehicle parameters range to trigger the Valve operation. Such vehicle parameter includes Engine RPM, Throttle Position and Vehicle Speed. Slider interface are utilized for the selection of those parameters range/band. Valve preset positions inside or outside the range/band can also be manually selected. ● Geo Mode: Create a geographic circle around an address of interest to trigger the valve to a certain position upon entering the circle. The valve can also be triggered to a certain position upon leaving the geographic circle and even trigger a change to Matrix Mode. VAREX muffler technology: The XForce VAREX muffler utilizes our patented technology to combine both the design of the stock muffler and the performance muffler into one single compact unit. A sophisticated butterfly valve mechanism is implemented to redirect the exhaust gas flow and vary between the two. For higher sound level, the exhaust flows are directed through the opening path and produces maximum power with a robust sound level (or the “sports car note”) and near-zero resistance. Whilst for lower sound level, the exhaust flows are directed through the chambered path (similar design with the stock muffler), and produces minimum sound level that gives you the best in-car comfort. Angle of the valve is also controllable, which can be adjusted to stop at various points between sports mode and silence mode. This gives you further freedom to set the optimal sound level according to your desired preference. The latest VAREX Smart Box Control Module serves as a bridge between the users and the Varex mufflers. Through the App and the Module, the user will be able to fine tune the exhaust sounds and performance levels to suit different occasions and the user’s preferred driving styles.
