Redback has built performance exhaust systems in Australia since 1979. Their Extreme Duty project launched in 2012 with one specific goal. Build the toughest bolt-on 4WD exhaust system available anywhere in Australia. Since then every Redback Extreme Duty system has been re-engineered from the ground up for the real world conditions Australian 4WD owners actually drive in.
What makes Redback different from generic exhaust brands is that their engineers fit the full range of common aftermarket accessories to a test vehicle before they design each system. Long range fuel tanks, side steps, larger spare wheels and common touring accessories all go on the vehicle before Redback starts the fitment process. This means the exhaust you buy for your accessorised HiLux, LandCruiser or Ranger actually fits a real world build rather than a stock showroom vehicle.
The Redback Extreme Duty range is the flagship Redback product line and the most popular exhaust system we fit at our Cardiff workshop in Newcastle. Every Extreme Duty kit uses 10mm thick four-bolt flange plates instead of the industry standard 8mm two or three bolt plates. Tube-to-tube connections replace the standard gasket systems that blow out on cheaper exhausts over time. Straight-through performance mufflers come with an internal reinforced bulkhead that protects against strikes during off-road use.
Every Extreme Duty kit comes with a comprehensive installation package including OEM gaskets, new rubber isolators, custom Australian-made gaskets, German-made Wurth hardware and a stainless 304 exhaust tip. Every piece is individually packaged and protected.
Extreme Duty systems also feature modular sound components. You choose between a straight pipe-only setup, a round resonator or a large muffler option. You can swap these components after the exhaust is fitted without removing the whole system. Newcastle 4WD owners who want a quiet note for daily driving and the ability to open it up for off-road weekends through the Hunter Valley use this feature regularly.
Modern diesel 4WDs from 2015 onwards run a Diesel Particulate Filter as part of the factory emissions system. A DPF back exhaust starts after the factory DPF and replaces the rest of the 4WD exhaust system from that point back to the tailpipe. This gives you the performance and sound benefit of an aftermarket exhaust without removing or modifying the factory DPF which keeps the vehicle emissions compliant on NSW roads.
We stock Redback DPF back exhaust systems for the Toyota HiLux GUN series, Toyota LandCruiser 79 Series, Toyota LandCruiser 300 Series, Ford Ranger and Nissan Navara NP300 at our Cardiff workshop in Newcastle. If your 4WD runs a factory DPF and you want an exhaust upgrade that keeps your vehicle compliant, a DPF back exhaust is the correct starting point.
A turbo back exhaust replaces the full exhaust system from the turbocharger outlet back. This is the most comprehensive exhaust upgrade available for a turbo diesel 4WD and produces the largest gains in power, torque and exhaust gas temperature reduction.
Redback turbo back systems suit pre-DPF platforms including various Toyota LandCruiser series, older HiLux models, Nissan Patrol and Navara variants and other turbo diesel 4WDs that do not run a factory DPF. Our technicians confirm which system suits your specific engine and year before installation at our Cardiff workshop.
Redback manufactures twin exhaust setups for popular 4WD platforms that benefit from a dual exit system. The Toyota LandCruiser 79 Series twin 4 inch turbo back exhaust is one of the most popular exhaust upgrades we fit at our Cardiff workshop in Newcastle. Redback engineers this specific system to clear the factory ARB long range fuel tank without modification and adjustable tip brackets allow our technicians to position the exits precisely on your specific build.
Twin exhaust systems deliver a deeper, more pronounced exhaust note alongside the performance benefits and suit LandCruiser 76 and 79 Series owners who want the full audio presence that matches the capability of the platform.
A dump pipe connects the turbocharger outlet to the rest of the exhaust system and is one of the most restrictive points on many stock 4WD exhaust systems. Upgrading to a larger diameter Redback dump pipe reduces back pressure at the turbo outlet and improves exhaust gas flow from the first point in the system.
We stock Redback dump pipes for the Toyota LandCruiser 75, 78 and 79 Series, LandCruiser 105 Series and Nissan Patrol GU at our Cardiff workshop in Newcastle.
If you want to fit a Redback exhaust system to a modern diesel 4WD that runs a factory DPF, a Redback DPF adapter kit bridges the connection between the factory DPF outlet and the aftermarket exhaust system. This lets you run a full Redback performance exhaust on a DPF equipped vehicle without cutting, welding or custom fabrication.
We stock Redback DPF adapter kits for the Toyota HiLux Fortuner 2015 onwards, Toyota LandCruiser 76 Series 2016 onwards, Toyota LandCruiser 70 Series 79 2016 onwards, Ford Ranger 2016 to 2022 and Nissan Navara NP300 2015 onwards at our Cardiff workshop in Newcastle. If you are unsure whether your vehicle needs a DPF adapter kit alongside an exhaust system, contact our team before purchasing and we will confirm the correct setup for your specific model and build date.
Redback manufactures every exhaust system at their facility in Epping, Melbourne. Every component including the pipe, muffler, flanges, brackets and hardware is designed and produced in Australia. For Newcastle 4WD owners who invest in a performance exhaust, buying an Australian-made system means parts availability, warranty support and technical assistance all sit locally rather than overseas.
Redback uses electric mandrel benders to shape every pipe in their range. Electric mandrel bending produces a more consistent and precise bend profile than the hydraulic benders most competitors use. The result is a pipe that maintains its full internal diameter through every bend which maximises exhaust gas flow and delivers a superior fit against the factory mounting points on your 4WD. Our technicians notice the difference in fitment quality between Redback 4WD systems and cheaper alternatives every time we compare them on the same vehicle at our Cardiff workshop.
The exhaust connections that fail most often on cheaper systems are the flange joints. Standard industry practice uses an 8mm two or three bolt flange plate with a gasket between the faces. These joints flex under heat cycling and vibration and blow the gasket out over time. Redback uses 10mm thick four-bolt flange plates with tube-to-tube connections that eliminate gasket failure entirely. On a touring build or a work vehicle that does serious kilometres across the Hunter Valley and beyond, this difference shows up in service life.
Redback builds interchangeable sound components into every Extreme Duty system. After installation you can swap between a pipe-only straight-through setup, a round resonator for a moderate note or a large muffler for a quieter daily driving tone. Each component bolts on and off without removing the main system. Newcastle 4WD owners who daily drive their vehicle but also use it on off-road weekends through the Hunter Valley regularly take advantage of this feature.
Redback engineers every Extreme Duty system with a fully accessorised test vehicle before the design is finalised. Long range fuel tanks, side steps, larger spare wheels and common touring accessories all go on before the system is developed. This matters for Newcastle 4WD owners who run ARB or similar long range tanks, canopies, side steps and other accessories because the system fits the real vehicle rather than requiring modifications to clear aftermarket gear.
Every Redback 4WD exhaust system carries a 5 year warranty as standard. When you purchase through us as an authorised Redback dealer and register your purchase online, that warranty doubles to 10 years. No online marketplace, unauthorised reseller or grey market importer can offer this extended warranty. Buying Redback 4WD exhaust in Newcastle through us gives you twice the warranty protection at no additional cost.
A factory exhaust system prioritises emissions compliance, noise reduction and cost rather than maximum exhaust gas flow. Replacing it with a larger diameter Redback mandrel bent system reduces back pressure, allows exhaust gases to exit the engine faster and gives the turbocharger more consistent flow conditions to work with.
For a heavily loaded touring HiLux, a towing LandCruiser or a work vehicle that spends days on end across the Hunter Valley and beyond, the power and torque improvement from a properly fitted Redback exhaust system is noticeable under load where factory systems are most restrictive.
Exhaust gas temperature or EGT is the temperature of gases exiting the turbocharger. High EGTs damage turbochargers and engines over time particularly on heavily loaded diesel 4WDs pulling trailers, running long range tanks or climbing steep terrain. A larger diameter exhaust system allows gases to exit faster which reduces heat buildup in the system and keeps EGTs in a safer operating range.
Every Redback Extreme Duty system comes with an oxygen sensor bung and NPT bung fitted as standard so you can install an EGT probe and monitoring equipment without drilling the pipe yourself. Our technicians fit EGT probes alongside Redback 4WD exhaust installations regularly at our Cardiff workshop.
Reducing exhaust back pressure reduces the amount of work your engine does to push gases out on each combustion cycle. Less work on the exhaust stroke means more energy available for driving which can translate to improved fuel economy particularly at highway speeds and under sustained load conditions like towing or climbing grades.
For Newcastle 4WD owners who cover long distances through the Hunter Valley, run regular work site kilometres or tow caravans and camper trailers, the fuel economy benefit from a Redback 4WD exhaust upgrade accumulates over the kilometres.
A factory exhaust system runs the smallest diameter pipe that meets noise regulations and emissions compliance. Redback performance exhaust systems use larger diameter pipework and performance muffler options that produce a deeper, more purposeful exhaust note without crossing into the aggressive drone that makes a vehicle unpleasant on long drives.
The modular sound component system means you choose the note that suits your use. A straight-through pipe for maximum sound on the tracks or a large muffler for comfortable daily driving through Newcastle. The same system delivers both depending on what you bolt on.
