● Manual Mode: Manually adjust the valve position of the muffler to certain position/degree. 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.

Ratings and Reviews
Great app and product
This app works 100% as described and I’ve never had an issue (if only the mufflers themselves were as flawless). A couple of suggested improvements as follows, but these would just be tweaks to something that already works extremely well.
- allow changes to matrix and geo modes whilst car not running (and then upload when next connected)
- In matrix mode, show when each parameter is within band within a profile (to assist tweaking). Currently only indicates when a profile is active (when all 3 parameters are in band).
- Enable smaller adjustments to parameters within matrix mode (ie. less than 1000rpm band width).
Defaults to closed valve every start up
The app works quite well however my only real fault I would say is that the valve defaults to closed on every startup. The varex system should remember last valve setting before switched off. It kind of gets annoying having to open the app every time I jump in the car to have a bit of noise and some better exhaust flow. I definitely would not push a car whilst the valve is closed as it feels restricted due to not enough flow. Xforce please resolve this issue and the smart box will definitely be smart. Would be a 5 star app definitely if I didn’t have to open the app on every start up.
Great system and app
I have the complete system on my gen f GTS. It’s amazing, all the noise when I want it and no drone and silence when I need it. The geo feature keeps my partner happy as well. A big thumbs up. The only thing I could ask is that the next update allows users to change settings without being linked to the smart box. And then automatically updating the settings once becoming reconnected.
Up to six family members will be able to use this app with Family Sharing enabled.
