Varex Valved Exhaust Systems: Your Sound, Your Way
At the heart of XForce’s innovation is the Varex Valved Exhaust System, a patented design that blends the characteristics of a stock muffler with the performance of a straight-through system, all in one unit.

Key Benefits:
- Adjustable Sound Levels: Thanks to an internal butterfly valve, you can switch between quiet, stock-like operation and full-throttle race mode at the touch of a button.
- Infinite Control: The valve isn’t just open or closed, it’s fully adjustable, allowing you to fine-tune the exhaust note to suit your mood or environment.
- Plug-and-Play Installation: No hard-wiring required. The system includes a remote control and water-resistant connectors for easy setup.
- Durability: Built with premium materials and engineered for longevity, Varex systems are designed to withstand daily driving and spirited use.
Whether you're leaving for work at dawn or hitting the track on the weekend, Varex gives you the flexibility to tailor your exhaust note without compromise.
Varex SmartBox: Intelligent Exhaust Control
For those seeking even more control, XForce offers the Varex SmartBox, a Bluetooth-enabled controller that transforms your exhaust system into a responsive, intelligent unit.
SmartBox Features:
- Manual Mode: Choose from five preset valve positions (Closed, 25%, 50%, 75%, Open) or create your own custom settings via the smartphone app.
- Matrix Mode (OBD-II required): Automatically adjusts the valve based on real-time data like RPM, throttle position, and vehicle speed.
- Geo Mode: Define quiet zones on a map, such as residential areas or your workplace, and the system will automatically reduce sound when you enter them.
- Live Feedback: See valve position changes in real time on your phone, eliminating guesswork and enhancing user experience.
The SmartBox isn’t just a gimmick, it’s a practical solution for drivers who want performance without the drawbacks of a permanently loud exhaust. Whether you're navigating city streets or carving through country lanes, the SmartBox ensures your car sounds exactly how you want it to, when you want it to.

XForce’s Varex systems offer a rare blend of performance, versatility, and refinement. For drivers who demand more from their exhaust, without sacrificing comfort or compliance, the Varex range is a compelling choice.
