What’s not to like about performance exhaust systems? You get the benefit of additional power, an engine that’s free to breathe, and a sound to die for. And in systems with more attention to detail and the use of better materials, there are improved aesthetics and an exhaust that’s built to last. With all the options currently on the Aussie market, choosing what’s right for your vehicle can be a painstaking task. Unless, of course, you choose the locally designed and manufactured systems from Sydney-based Xforce.
Who is Xforce?
Xforce is one the most recognisable players in the performance exhaust market. They first made their name with bespoke exhausts for staple Australian favourites, such as the legendary HSV GTS, or the equally good Falcon XR6, and later expanded their product lineup to cater to JDM classics that are the Subaru Impreza STi and WRX, the Mitsubishi Lancer Evo, the Nissan 370Z, and Euro tuning stalwarts typified by the likes of the VW Golf GTi and R, the Audi RS3 and BMW M3.
All their exhaust systems undergo extensive R&D, with individual parameters of each vehicle going through thick and thin to extract the last drops of power. This is paired with innovative design features to tailor exhaust sounds that best meet customer needs and wants, along with the use of advanced production processes and high-quality materials to ensure that your exhaust not only performs but also lasts.
Proprietary Tech
One of the key innovations of Xforce Exhaust Australia is their Varex mufflers and smart boxes. This is the company’s patented technology that combines the design of the stock muffler with the performance attributes of aftermarket mufflers into one single, compact unit. The inclusion of a sophisticated butterfly valve mechanism is used to redirect exhaust gas flow and fine-tune the sound. A louder exhaust note is achieved by passing the gases through a short and open path. This not only gets the highest volumes but with fewer restrictions, also gets the best performance.
Building on the abilities of the Varex mufflers is the user adjustability provided by the Xforce smart box. This is the company’s patent-pending technology that allows users to manually or automatically adjust the exhaust sound level, something that can be conveniently done with a simple-to-use smartphone app.
A Wide Range of Choices
Xforce offers an extensive range of exhaust products. These cover popular vehicles sold in Australia as well as models specific to other markets. The company allows users to mix and match products in a modular, bolt-on design.
High-flow catalytic converters in varying cell counts (100 and 200) and different diameters and shapes to suit the stock tubing (2,2.5 and 3 inches) in either a full ceramic or combo metal build are just an intro to the wide inventory on offer. Bigger engines like the inline 6 and V8s in classic Aussie cars can benefit from better airflow with exhaust merge collectors, that collect individual header pipes and mid-section tubing into a single pipe. Engines with forced induction will puff out more power with a revised downpipe.
Other Xforce specialties are the unique X-pipe designs paired with the Varex system to boost exhaust velocity and improve sound characteristics. And let’s not forget the range of tips for added visual effects. Here buyers can choose from angle-cut tips in different diameters and finishes, ranging from the stunningly eye-catching burnt blue tips in stainless steel to the minimalist matte black carbon tips fitted as stock on more high-end performance cars.
To round out the wide selection, Xforce also supplies all mounting hardware and exhaust accessories in the same high-quality materials. This covers items like flanges, gaskets, hangers, pie cuts, and O2 sensor bungs and extension looms to accommodate the factory oxygen sensor.
Cat-back, Header-back and Axle-back Offerings
Cat-back systems from Xforce Exhaust Australia change all the car’s stock tubing from the catalytic converter to the tips. These are offered for more accessible hatches and sedans, such as the Kia Cerato GT, its Hyundai sibling the i30 N-line and N-Performance and the Mazda3; performance-oriented cars like the Honda Civic Type-R and the Toyota Yaris GR, and traditional American muscle cars (Chevy Camaro and Ford Mustang). Most can be had with the Varex system included, and with varying tubing widths suited to the engine.
Header-back systems change the entire factory exhaust piping, from the headers exiting the exhaust manifold to the tips. These offer the biggest gains in power and torque, and when supplied with a Varex muffler and smart box, the loudest sound. They’re good for bigger-displacement cars but are also preferred in large SUVs and 4WDs like the Toyota Landcruiser, the Jeep Grand Cherokee and Nissan Patrol. In diesel variants of these cars, turbo-back exhausts are used.
Axle-back performance exhaust systems from Xforce are at the same time the most affordable, add visual and aural appeal to any car, and are built to last. These change parts from the rear axle to the tips. They too can be had in different grades of steel, with or without the Varex muffler, and in a range of exhaust tips.
Final Word
If you’re shopping for an exhaust to open up the full potential of your car, then you can’t go wrong with the offerings from Xforce. The company builds top-quality systems to suit a range of cars, has a range of innovative designs for a bit of crackle and pop, and will provide the performance boost you and your car need. And you don’t have to look hard to find them. Xforce exhausts are available direct from the company and Australia-wide from respected resellers.
