4x4 Performance Exhaust Systems for Trucks and SUVs

Heavy-Duty DPF Delete Pipes for Maximum Flow

For off-road and competition use, the Diesel Particulate Filter (DPF) can be a major bottleneck, limiting gas flow and robbing your engine of power. Our DPF delete pipes are engineered to remove this restriction entirely. Fabricated from high-grade 304 or 409 stainless steel, these pipes offer exceptional durability and corrosion resistance, ready to withstand harsh Australian conditions. 

Budget-Friendly DPF Dummy Replacements

Achieving unrestricted exhaust flow doesn't always require premium-grade materials. Our DPF dummy replacements provide a practical and affordable alternative for removing the factory DPF. These units serve the same primary function as a full delete pipe - eliminating the restrictive filter to improve performance - but are constructed with cost-effectiveness in mind. 

They are a perfect solution for drivers who want the tangible benefits of a DPF-free system, such as better engine response and torque, without the higher investment. This approach allows you to address the main performance bottleneck in your exhaust system efficiently, freeing up your budget for other modifications. While focusing on value, these replacements are still built for a direct fit, making installation straightforward.

High-Performance 4x4 Cat Back Exhaust Systems

If you are looking for a significant upgrade in sound and performance without altering your vehicle's core emissions components, a cat-back system is the ideal choice. These systems replace everything from the catalytic converter to the tailpipe with larger diameter, mandrel-bent tubing for smoother, faster exhaust flow. 

This upgrade is one of the most popular ways to get that deep, aggressive exhaust note every 4x4 owner loves, while also providing a modest but noticeable boost in horsepower and torque. It's often considered the best 4x4 performance exhaust modification for a balance of sound, power, and road legality, offering a satisfying improvement you can feel and hear on every drive.

Complete Extractor and Exhaust Upgrade Kits

Moving beyond a cat-back system, combining new extractors with a full exhaust kit delivers a far more substantial performance leap. Factory exhaust manifolds are notoriously restrictive; our complete kits replace them with precision-engineered extractors that dramatically improve exhaust scavenging from each cylinder. 
Full 4x4 Performance Exhaust Engine Back Systems for Complete Overhauls
For the ultimate, no-compromise upgrade, a full engine-back system replaces every component of your factory exhaust. From the engine block or turbocharger all the way to the tailpipe, these systems are designed as a single, cohesive unit for maximum performance. There are no bottlenecks, no restrictions, and no compromises. 

Sourced from the top names in 4x4 performance exhaust Australia, these kits are built for those who demand the absolute peak of performance from their truck or SUV, whether for competitive racing or building a highly capable outback tourer.

Custom Crossover Pipes and Turbo-Back Solutions

Every vehicle build is unique, and sometimes an off-the-shelf kit isn't enough. Our range of specialised components gives you the flexibility to create a truly custom setup. Crossover pipes for V-engines balance exhaust pulses between cylinder banks, smoothing out the exhaust note and improving scavenging. 

For turbocharged vehicles, a turbo-back system with cat deletes offers the most direct path for exhaust gases, allowing the turbo to spool faster and operate more efficiently for immediate power delivery. These individual parts are for the builder who knows exactly what they want, allowing you to fine-tune your vehicle's sound and performance characteristics to perfectly match your specific needs.
