Description
VAREX Smart Box control module for the Varex mufflers is one of XForce Performance Exhausts’ latest patent pending technologies. It brings the ultimate user experience of volume adjustable exhaust to the performance car enthusiasts. Through this technology, our users will be able to have full control of how their Varex exhaust systems sound and perform.

***This App will work exclusively with the VAREX Smart Box control module.***

● 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.

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.

Comments on XForce Varex for Android

★★★★☆ Vaughan Rooke · Oct 1, 2019
Giving this a solid 4 stars. The UI is great, very slick. Connects quickly and easy to switch between modes and customize settings. A real marriage-save. So handy to flick the app open and select the Wife protocol :) To get the 5th star (take note devs - I WILL edit if the feature arrives!) I'd like to see the ability to set narrower bands, especially on the RPM. The minimum bandwidth is 1000 revs - where my "droney" band is only 500, between 1800-2300. Have got around this by enabling 2 profiles with different throttle settings, but ideally this would be doable in a single setting. Addressing some comments below: - The "Uncial" message. I've never seen this - the unit seems to self calibrate on the first actuation of the valve after starting up by closing and opening fully twice in quick succession. From there on in it just sticks to the program. - App doesn't need to stay active or even open. Even without the phone in the car the last setting remains active.
★★★★★ Paul Hagan · Dec 17, 2016
Great app. Great product Finally this app is available for my android. It just works. And absolutely complements the great exhaust system it connects to. Very happy.
★★☆☆☆ Warren Hefferan · Dec 27, 2021
Pretty rubbish to be honest, I paid extra to use matrix, GPS, and I'm constantly pressing the calibrate button/text. I'm using the remotes, I suggest not paying the extra for matrix and settle for the remotes.
★★☆☆☆ Morgan Veloz · Sep 25, 2023
Paid extra for the smart box, and now it's just extra weight in my car. The app doesn't calibrate correctly, and that bugg needs to be addressed It's unusable even hitting calibrate text. I'm using remote with the old box now Please fix this calibrates issue. It's the main issue on this app If they don't fix it soon, it's a waste of $300, honestly
★★☆☆☆ TemperZz · Jun 30, 2022
Just got my golf r 7.5 with the force varex exhaust, used the app for the first time, and it worked, second time it kept giving me valve calibration timeout error and I have no idea how to fix it, no info online or anything else
