Beaudesert Exhaust – Toyota LandCruiser 105 Series 1998-2007 4.2L 1HZ Diesel
Give your 1998-2007 Toyota LandCruiser 105 Series Solid Axle (4.2L 1HZ Diesel – naturally aspirated or aftermarket turbo) the upgrade it needs with this premium Australian-made Beaudesert mandrel-bent exhaust system. Built for heavy-duty work, remote hauls, towing, or daily reliability – this system eliminates factory restrictions, delivers noticeable torque/response improvements, better fuel economy, and a deeper rumble without excessive noise or rego headaches.
Key Features
- Mandrel-bent stainless steel tubing for smooth, unrestricted exhaust flow (sized optimally for the 1HZ – 2.5″ standard or 3″ for turbo conversions based on real-world testing and customer feedback)
- High-grade stainless construction – Rugged series in durable 441-grade stainless or upgrade to Ultimate 304 marine-grade for superior corrosion resistance and polished finish
- Vehicle-specific fit for 1998-2007 105 Series Solid Axle 4.2L 1HZ Diesel – bolts on from manifold/turbo rearward for easy install and maximum gains
- Heavy-duty brackets, solid hangers, and thick flange plates for secure, vibration-free mounting and long-term durability in tough Aussie conditions
- Straight-through high-flow muffler design – refined sound under load with minimal cabin drone on highway runs
- Designed and manufactured in Australia to handle extreme heat, dust, heavy loads, towing, off-road tracks, and everyday grind
Benefits You'll Feel Every Day
- Improved Throttle Response & Torque – Stronger low-end pull for loaded starts, steep climbs, or towing trailers – especially noticeable with aftermarket turbo
- Better Fuel Economy – Real-world diesel savings from freer breathing – pays off on long remote runs or fleet duties
- Deeper, Throatier Exhaust Note – Tough rumble on acceleration, but quiet and drone-free at cruise – sounds proper without annoying the crew
- Engine Longevity – Reduced backpressure eases strain on the 1HZ engine and turbo (if fitted) for fewer long-term issues
- Lower EGTs (with Turbo Setup) – Cooler exhaust temps under load for better performance and protection
- Full Compliance & Peace of Mind – No emissions tampering – road-legal for rego, roadworthy, and defect checks in NSW/Australia
Whether it's carrying crew/tools, towing gear, or hitting outback tracks – this Beaudesert exhaust turns your 105 Series into a more responsive, efficient, and reliable workhorse that handles the hard yakka without compromise.

Frequently Asked Questions
Is this 2.5-inch exhaust system the best choice for a naturally aspirated 1HZ 105 Series?
Yes, for the naturally aspirated 1HZ engine, a 2.5-inch system is often the sweet spot. It provides enough flow to improve engine efficiency and throttle response without sacrificing the crucial low-end torque that the 1HZ relies on. Larger piping can sometimes lead to a loss of bottom-end "grunt," making this 2.5-inch system ideal for maintaining everyday drivability.
Will this exhaust fit with my 105 Series solid-axle suspension?
Absolutely. This system is specifically designed for the solid-axle 105 Series chassis geometry. We have mapped the path to ensure that the exhaust routing provides optimal clearance from your front suspension components, driveshafts, and the solid axle, even when the suspension is at full articulation.
Does this exhaust produce an annoying cabin drone?
No. We have specifically tuned the internal design of the muffler and resonator to eliminate the drone that often plagues 105 Series vehicles with aftermarket exhausts. You get a deeper, more refined engine note, but the cabin remains quiet and comfortable for all occupants during long-distance highway cruising.
Can I install this exhaust system myself?
Yes, it is designed as a complete bolt-on kit. We provide all the necessary high-tensile hardware, gaskets, and heavy-duty hangers that align with the factory mounting points. It is a straightforward job for anyone with basic mechanical tools, with no need for welding or custom modifications.
Why should I consider the stainless steel option for my 105 Series?
If you use your LandCruiser for its intended purpose—exploring, beach driving, or coastal touring—mild steel will eventually succumb to rust. Stainless steel provides unmatched corrosion resistance against salt, mud, and water. It is a long-term investment that ensures your vehicle’s exhaust will remain in top condition for years, protecting your investment and your vehicle's performance.
