Upgrading the exhaust on a modern diesel vehicle is one of the most effective ways to unlock better sound and improved throttle response. Our catalogue is filled with high-quality, direct-fit systems designed for Australia's most popular 4x4s and utes, built to withstand tough conditions and deliver immediate results you can hear and feel.
Get the Best Fit with DPF-Back Exhaust Systems
A DPF back exhaust delivers the perfect balance of performance, sound, and compliance for today's diesel vehicles. By retaining the factory DPF, you sidestep potential legal issues and dashboard warning lights while still gaining major benefits.
The larger diameter piping, often stepping from 2.5 to 3 inches or even a full 4 inches, allows the engine to breathe more freely post-filter. This reduction in restriction can lead to sharper throttle response and a much deeper, more satisfying exhaust note.
Whether you need a simple pipe-only setup for a cleaner look or a complete system for a Toyota Land Cruiser, finding the right DPF-back exhaust is a straightforward, high-impact modification for any modern 4x4 or commercial vehicle.
Upgrade with Durable Stainless Steel Systems
The material your exhaust is made from is just as important as its design. Our systems are predominantly crafted from high-grade stainless steel, the premium choice for longevity and performance.
Stainless steel provides superior resistance to rust and corrosion caused by road salt, mud, and water crossings - a non-negotiable for Australian conditions. It also handles extreme heat cycles without cracking or becoming brittle. Options like 409-grade stainless offer an excellent blend of durability and value, standing up to abuse both on and off the road.
Choosing a stainless steel system, whether it’s a full turbo-back or a DPF-back with a hotdog resonator, means you are investing in a part that will perform reliably and look great for years to come. The quality of the materials sets the foundation for every other choice you make.
Explore Turbo-Back Exhaust Systems for Maximum Performance
Besides DPF-back exhausts, for those chasing the absolute peak in power and sound, a full turbo-back exhaust is the ultimate solution. These systems replace every component from the turbocharger rearward, removing the most restrictive factory parts to allow for maximum gas flow.
You will find options in our range from 3-inch and 4-inch mandrel-bent pipes to twin-exit designs, all engineered to drastically reduce exhaust gas temperature and backpressure. This is the path for heavily modified vehicles, competition builds, or anyone looking to get the most out of a custom tune.
Choose Between Catalytic Converter or Straight-Through Options
Customising your vehicle's sound and performance level often comes down to the components you include in the system. While DPF-back systems retain the main emissions device, turbo-back systems give you the choice of including a high-flow catalytic converter or opting for a straight-through pipe.
Including a cat helps manage emissions, making it a suitable choice for street-driven vehicles. On the other hand, a cat-delete pipe paired with a muffler or resonator provides a louder, more aggressive tone with maximum flow for off-road applications.
A popular setup for the DPF-back exhaust is one that balances flow with an acceptable sound level. This choice allows you to tailor the exhaust note from a deep, controlled rumble to an all-out roar, putting you in complete control of your vehicle’s character.
Find Tailored Solutions for Unique Vehicle Applications
A one-size-fits-all approach doesn't work for exhaust systems. Every vehicle has a unique chassis, suspension setup, and underbody layout, which is why model-specific kits are essential for a perfect, hassle-free installation.
We offer solutions engineered for specific applications, such as a side-exit DPF-back exhaust to provide better clearance for towing or custom tray setups. A correctly designed 200 series DPF-back exhaust will clear long-travel suspension components, while a purpose-built NP300 DPF-back exhaust accounts for the vehicle’s specific hanger locations and routing.
These tailored systems are designed for a direct bolt-on fit, saving you hours of fabrication and guaranteeing that every component sits exactly where it should without rattling or interfering with other parts.
