XFORCE performance exhaust systems

XFORCE is distinguished by its Varex technology, which adjusts exhaust sound by changing the valve position within the silencer. The SmartBox module controls compatible systems through a Bluetooth app.

Matrix Mode uses OBD-II data such as engine speed, throttle position and road speed, while Geo Mode links settings to location. XFORCE Varex exhausts suit drivers who want programmable sound behaviour rather than a single fixed exhaust character.

SmartBox Manual Mode can position the valve between fully open and fully closed. Users can save their preferred positions as presets. The app displays the current opening position, and a compatible setup can also retain an existing Varex remote controller.

History and development. XFORCE was founded in Australia in 2001, with its development base associated with New South Wales. From its Australian exhaust-market origins, it expanded into a business serving international customers through a distribution network.

The business today. The company now operates Australian and US teams and develops applications for multiple vehicle manufacturers. Varex and SmartBox remain important product families, alongside complete systems and universal components. Applications are researched and developed in Australia; this should not be interpreted as a claim that every manufacturing stage takes place there.
