XForce VAREX: Why a Valve-Controlled Exhaust Is the Smartest Upgrade You Can Make

There's a reason XForce VAREX systems have become the exhaust of choice for Australian enthusiasts who actually drive their cars daily. Not just on track weekends. Not just for show. Every single day.

The concept is simple: a motorised butterfly valve sits inside the muffler. Open it, and exhaust gases bypass the silencing chambers entirely — you get the full, unrestricted roar the engine was built to make. Close it, and the gases route through the baffles as normal, dropping the decibels to a level your neighbours won't complain about.

One car. Two modes.

That's what makes VAREX genuinely different from every other aftermarket exhaust on the market. You're not choosing between a weekend warrior setup or a daily driver compromise. You're buying both — in one system.

Open mode delivers the kind of sound that makes people turn their heads in carparks. Closed mode is refined enough to take on a long highway run without arriving with a headache.

The switch? A small wireless remote that mounts under your dash in about ten minutes.

304 stainless steel — built to last Australian conditions

XForce don't cut corners on materials. Their systems are mandrel-bent 304 stainless steel throughout. That matters in Australia, where coastal salt air, red dirt roads, and temperature extremes accelerate corrosion on cheaper mild steel systems within a few years.

Mandrel bending keeps the tube diameter consistent through every curve, which means exhaust flow is never restricted by a flattened bend. More flow means more power, less heat soak, and better scavenging at high RPM.

Direct bolt-on fitment for 200+ vehicles

XForce catalogue covers everything from Nissan GT-R R35 and Toyota Supra A90 to Ford Ranger and Subaru WRX. Every system is engineered to match the factory mounting points exactly. No cutting, no fabrication, no guesswork. You're looking at a Saturday morning install for most platforms.

What does it actually cost?

XForce VAREX systems start from $349 for universal and entry-level fitments, ranging up to $3,499+ for full catback systems on performance platforms like the R35. Compared to the cost of owning two separate exhausts — or worse, a loud system you regret every morning on the school run — VAREX pays for itself in the first week.
