Why Choose the Extractor System?

The extractor manifold is the ultimate upgrade for your 79 Series 1HZ. Unlike the restrictive factory cast manifold, our mild steel extractor features individual tuned pipes that significantly reduce back pressure and improve exhaust scavenging. Combined with the 2.5" stainless steel exhaust system, this delivers the maximum possible performance gains for your 1HZ engine – perfect for touring, towing, and serious outback work.

Frequently Asked Questions

Will the outback exhaust fit my Toyota Landcruiser 79 Series?

This outback exhaust system with extractor is specifically engineered for the Toyota Landcruiser 79 Series Single Cab Ute with the 4.2L 1HZ naturally aspirated diesel engine from 1999 to 2007. Please confirm your vehicle specifications before ordering, or contact us for fitment advice.

What's the difference between this and the standard exhaust system?

This system includes an extractor manifold that replaces your factory cast iron manifold. The extractor features individual tuned pipes for each cylinder, dramatically reducing back pressure and improving exhaust scavenging for maximum performance gains. It's the ultimate upgrade for serious 79 Series owners.

What performance gains can I expect with the extractor?

The extractor manifold combined with the 2.5" exhaust system delivers the maximum possible performance gains for the 1HZ engine. You'll experience significantly improved throttle response, better power delivery throughout the rev range, enhanced torque for towing and hill climbing, and potential fuel economy improvements of 10-15% depending on driving conditions. The difference is particularly noticeable when towing or carrying heavy loads.

How loud is the outback exhaust system?

Outback exhaust system with extractor delivers a deep, quality exhaust note that complements the 1HZ's character without being excessively loud. The extractor provides a slightly more pronounced exhaust note than the factory manifold while remaining comfortable for long-distance touring and daily driving.

What's included in the complete system?

The complete system includes the extractor manifold, all pipework from the extractor to the rear tailpipe, and all necessary gaskets, and mounting hardware for bolt-on installation.

What warranty is included?

This complete exhaust system including the extractor manifold is backed by our comprehensive 5-year warranty, covering manufacturing defects and material failures under normal use. Mild steel extractor has 2 year warranty

Can I install the outback exhaust and extractor myself?

If you have mechanical experience and the right tools (including a hoist or jack stands, socket set, and basic hand tools), DIY installation is possible. The extractor manifold requires removing the factory manifold and installing the new extractor with supplied studs and gaskets. However, we recommend professional installation for best results. Most qualified mechanics or exhaust shops can install this complete system in 3-5 hours.

What's the delivery time to my location?

Outback Exhausts offer fast shipping Australia-wide. Delivery typically takes 3-7 business days depending on your location. Remote areas may require additional time.

Will the outback exhaust improve towing and load carrying performance?

Absolutely! The extractor manifold and 2.5" exhaust system dramatically improve the 1HZ's ability to produce power and torque efficiently. You'll experience significantly better throttle response, improved hill climbing ability, and less strain on the engine when towing heavy loads or carrying equipment – essential for serious touring and station work.

Is this suitable for remote touring and outback use?

Yes! This system is specifically designed for Australian conditions and built from premium stainless steel to withstand the harsh environments that 79 Series Landcruisers are famous for tackling. The extractor manifold provides the maximum performance upgrade for remote touring, station work, and serious off-road adventures where reliability and power are critical.

What's the difference between 75 Series and 79 Series exhausts?

While both use the 1HZ engine, the 79 Series Single Cab has a different chassis and body configuration than the 75 Series, requiring a specifically designed exhaust system. This system is engineered specifically for the 79 Series Single Cab Ute (1999-2007) to ensure proper fitment and optimal performance.
