XFORCE Exhausts: Built for Performance. Designed by Enthusiasts.
XFORCE Exhausts are an Australian performance exhaust manufacturer, and the range covers what most people actually want from an aftermarket system: a better note, less restriction, and parts that bolt up without a fight.
The headline product is VAREX. It is XFORCE's patented valved muffler, and it solves the problem every loud exhaust eventually creates. You want the car quiet on the way to work and loud everywhere else. VAREX gives you both. A control unit opens and closes a valve inside the muffler, so you can run a subdued note through a residential street at 6am and open it right up on a back road an hour later. You make the call from the driver's seat instead of at the point of purchase.
Beyond VAREX, the cat-back systems are the volume seller. A cat-back replaces everything from the catalytic converter rearward, which is the section doing most of the work on both sound and flow. It also leaves the emissions hardware untouched, so it is the sensible first step on a street car that still has to pass inspection.
Fitment is where a lot of aftermarket exhaust buying goes wrong. XFORCE develops and tests in Australia, against Australian delivered cars, rather than adapting a system designed around a US or JDM spec that can sit differently in the tunnel. On a Subaru WRX in particular, where the exhaust routing is tight and the platform has changed across generations, that difference shows up on the hoist.
If you are weighing a cat-back against a full turbo-back, or you are chasing a specific note rather than a specific power figure, get in touch before you order. We would rather talk it through than have you send something back.
