VAREX™ mufflers utilize 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 be-tween 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. 

WHY THE SMART BOX?

The renowned VAREX Exhaust System was invented and manufactured by XForce Performance Exhaust.

VAREX exhaust has since been the most popular choice among the enthusiasts and professionals, who are seeking the flexible control of the sound level for their performance exhaust.

VAREX exhaust systems allow users to adjust the exhaust sound from stock-car like quiet to sports-car like growl by a click of a key fob button. 

We love our VAREX exhaust sound and performance, and we would prefer keeping the Varex exhaust on the “Open Mode” most of the time.

However, there is always some moments, the high volume exhaust sound is less desirable. We know that it is part of the nature of most performance exhausts.

Imagine the following scenario:

When you are cruising in a beautiful stretch of country road,  slightly tapping on the throttle pedal just to maintain the cruising speed, or simply let the cruise control taking over, most likely we would hear a low pitch, slight(or loud) humming exhaust sound resonating inside the cabin.Some of us might be fine with it, but to some, it could be a little bit too much to bear, especially during a long trip.

With Varex muffler installed,we could have reached for the Varex remote key fob, and quickly pressed the button to reduce the sound level. It is a good way to go, but yet not the most convenient one.

WE COULDN’T STOP THINKING, WHAT IF WE CAN CREATE A DEVICE THAT WILL KNOW WHEN AND HOW TO CHANGE THE EXHAUST SOUND FOR US, AND DO IT PRECISELY AND AUTOMATICALLY.

It will mean that this smart control system can sense the right moment, and produce the right exhaust sound for our enjoyment.

Gladly, our R&D team took up this challenge, and that was how the idea of Varex Smart Box Bluetooth® Exhaust Controller (VSBec) have been contemplated and created.

Our goal is to make the most user friendly Variable Exhaust System, and reduce the stress of  owning a loud performance exhaust.

By VAREX Smart Box, we believe that we have achieved our goal.

WHAT IS THE SMART BOX?

 Varex Smart Box is a control device with patent pending technology that let the user to manually and automatically adjust the exhaust sound level of the Varex exhaust.

The users can operate and make change to the settings of the Smart Box via an elegantly designed Smartphone App.
