Frequently Asked Questions

Will the outback exhaust fit my Toyota Landcruiser 79 Series?

This outback exhaust 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. 

What's the difference between manifold-back and engine pipe-back?

A manifold-back system starts from the exhaust manifold outlet and includes all pipework to the rear tailpipe. An engine pipe-back system is similar but start from a different connection point. Both provide complete exhaust replacement from the front of the system to the rear.

What performance gains can I expect from my 1HZ?

You'll experience improved throttle response, better power delivery throughout the rev range, and potential fuel economy improvements of 5-10% depending on driving conditions. The reduced back pressure allows your 1HZ engine to operate more efficiently, particularly beneficial when towing or carrying heavy loads.

How loud is the outback exhaust system?

The Outback exhaust system delivers a deep, quality exhaust note that complements the 1HZ's character without being excessively loud. It provides that distinctive Landcruiser sound while remaining comfortable for long-distance touring and daily driving.

What's included in the manifold-back system?

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

What warranty is included?

Outback exhaust system is backed by our comprehensive 5-year warranty, covering manufacturing defects and material failures under normal use.

Can I install the outback exhaust 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. This is a bolt-on system designed for straightforward installation. However, we recommend professional installation for best results. Most qualified mechanics or exhaust shops can install this system in 2-3 hours.

What's the delivery time to my location?

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

Will the outback exhaust improve towing performance?

Yes! The reduced back pressure and improved exhaust flow help the 1HZ engine produce power more efficiently, which is particularly noticeable when towing or carrying heavy loads. You'll experience better throttle response and less strain on the engine during demanding work.

Is this suitable for remote touring and outback use?

Absolutely! This exhaust 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. It's the perfect upgrade for remote touring, station work, and serious off-road adventures.

Does this system work with the factory manifold?

Yes, this manifold-back system is designed to work with your factory cast iron manifold. It replaces the exhaust system from the manifold outlet backwards. If you're looking for maximum performance gains, consider our extractor manifold system which replaces the factory manifold as well.

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.
