- Designed and manufactured in Australia to handle extreme heat, dust, heavy towing, off-road punishment, and everyday use
Benefits You'll Feel Every Day
- Reduced Turbo Lag & Strong Torque Gains – Faster spool-up and massive low-end pull for loaded starts, steep climbs, or towing trailers in the bush
- Improved Throttle Response & Power – Noticeable gains across the rev range – unlocks the 1HZ's potential with your aftermarket turbo setup
- Better Fuel Economy – Real-world diesel savings from freer breathing – pays off on long remote runs or work shifts
- Lower EGTs & Engine Protection – Cooler exhaust temps under load reduce strain on turbo and internals for longer life

Frequently Asked Questions
Is this exhaust system designed specifically for the solid-axle 105 Series?
Yes. The 105 Series features a solid-axle front end, which creates a different under-chassis layout compared to the IFS 100 Series. We have engineered this system to navigate the specific geometry of the 105 Series chassis, ensuring your new exhaust clears the front suspension and drivetrain components with room to spare.
How does this 3-inch exhaust benefit the 4.2L 1HZ engine?
The 1HZ is renowned for its reliability, but it is often hampered by the restrictive stock exhaust. Our 3-inch mandrel-bent system drastically reduces exhaust backpressure. Whether you are running a naturally aspirated 1HZ or have added an aftermarket turbo, you will notice improved throttle response, lower EGTs (Exhaust Gas Temperatures) under load, and more efficient engine operation.
Will this system drone on long trips in my 105 Series?
We have specifically tuned our muffler and resonator assembly for the 105 Series to eliminate interior drone. While you get that deep, throaty diesel note under load, the system remains whisper-quiet and comfortable at steady highway speeds, making it the perfect upgrade for long-distance family adventures.
Can I install this 105 Series exhaust in my home garage?
Yes, it is designed for DIY installation. The kit comes with everything you need: high-tensile hardware, gaskets, and heavy-duty, laser-cut hangers that align perfectly with your factory mounting points. You don’t need to do any cutting or welding—just unbolt the old system and bolt on the Beaudesert upgrade.
Why should I opt for the stainless steel version for my 105?
The 105 Series is a legend of off-road touring. If you take your vehicle onto the beach, through mud, or into coastal areas, stainless steel is the smartest choice for longevity. It provides industry-leading resistance to corrosion, ensuring that your exhaust won't rust out and remains in perfect condition for as long as you own the vehicle.
