Why the VAREX Smartbox?

The acclaimed VAREX Exhaust System was invented by XForce Performance Exhaust - it has been the most popular choice amongst enthusiasts who are seeking flexible control of their sound level.  The VAREX exhaust system allows users to adjust the exhaust sound from stock-car-quiet to sports-car-growl with a click of a key fob button.  We love our VAREX exhaust and prefer to keep it in ˜open mode„¢. However, there are always moments when the high volume exhaust is less desirable.

Imagine the following scenario:

You're cruising along a country road, tapping on the throttle pedal to maintain cruising speed, (or perhaps letting the cruise control take over). Presumably, you'd hear a low-pitch or loud-humming sound inside the cabin. Some might be fine with that but for many, it's too much to bear.  With a Varex muffler installed, you could reach for the remote key fob to reduce the sound. It's a good way to go yet not the most convenient.

Our goal was to make the most user-friendly Variable Exhaust System and reduce the stress of owning a loud performance exhaust. With VAREX Smart Box, we believe we've achieved our goal. This smart control system can sense the right moment, and produce the right exhaust sound for your enjoyment. Gladly, our R&D team took up the challenge, and that's how the idea of Varex Smart Box Bluetooth® Exhaust Controller (VSBec) was created.
