Performance Benefits

Experience dramatic improvements in turbo response, power delivery, and overall drivability. The 3" turbo-back design significantly reduces exhaust backpressure, allowing your turbo diesel to breathe freely. This translates to faster turbo spool-up, improved throttle response, noticeable power and torque gains throughout the rev range, and better fuel efficiency—especially when loaded with gear, passengers, or towing a trailer.

Why Turbo-Back for the Troopy?

The 78 Series Troop Carrier is often heavily loaded with equipment, passengers, and gear for remote touring, mining work, or expedition use. A turbo-back exhaust provides the greatest performance improvement by eliminating all factory exhaust restrictions from the turbo outlet. The result is maximum power gains, improved EGT (exhaust gas temperature) management under load, better fuel economy during long-distance touring, and enhanced turbo longevity due to reduced backpressure.

Built for Australian Work & Touring

The Troopy is Australia's ultimate workhorse and touring vehicle, and this exhaust is engineered to match its legendary toughness. Whether you're running mine site operations, crossing the Tanami Desert, or kitting out your Troopy for remote expedition work, this exhaust system handles it all. The premium stainless steel construction resists corrosion from salt, mud, and water crossings, while the robust mounting system ensures reliability on the roughest corrugated tracks and harshest conditions.

Frequently Asked Questions

Will the outback exhaust fit my Landcruiser 78 Series Troop Carrier?

The outback exhaust is specifically designed for Toyota Landcruiser 78 Series Troop Carrier VDJ78 models with the 4.5L V8 turbo diesel engine from 2007-2016. This will not fit other 78 Series variants (single cab, ute) or petrol models.

What's the difference between turbo-back and DPF-back exhausts?

A turbo-back exhaust replaces everything from the turbo outlet to the tailpipe, providing maximum performance gains. A DPF-back system retains the factory DPF (Diesel Particulate Filter) and only replaces the exhaust from the DPF back. Turbo-back systems deliver significantly better power, torque, and fuel economy improvements—critical for heavily loaded Troopys used for touring, mining, or expedition work.

How much power and torque gain can I expect from the Outback Exhaust system?

While exact gains vary based on vehicle condition and other modifications, customers typically report noticeable improvements in turbo response, mid-range torque, and overall power delivery. The most significant benefits are improved throttle response, faster turbo spool-up, and better performance when the Troopy is heavily loaded with passengers and gear or when towing. Many customers also report improved fuel economy, particularly during highway cruising and loaded touring.

How does the outback exhaust sound compared to stock?

You'll notice a deeper, more aggressive diesel note with enhanced turbo whistle compared to the restrictive factory system. The sound is purposeful and matches the Troopy's workhorse character without being excessively loud on long highway drives. It provides that classic turbo diesel growl that enthusiasts appreciate, especially under acceleration and boost.

Will the outback exhaust improve my fuel economy?

Yes, many customers report improved fuel economy, particularly during highway cruising and when the vehicle is loaded. The reduced backpressure allows the engine to work more efficiently, which can translate to fuel savings of 1-2L/100km in real-world conditions. The greatest improvements are typically seen when the Troopy is carrying a full load of passengers and equipment or towing.

What's included in the 5-year warranty?

The Outback Exhausts 5-year warranty covers manufacturing defects and material failures under normal use, including corrosion protection for the stainless steel construction. The warranty covers all exhaust components from turbo to tailpipe. It does not cover damage from accidents, improper installation, modifications, or off-road impact damage.

Is professional installation required for the Outback exhausts?

Yes, The Outback Exhausts strongly recommend professional installation for this turbo-back system. Proper installation requires removing the factory exhaust from the turbo outlet, ensuring correct gasket sealing at the turbo flange, proper alignment throughout the system (accounting for the Troopy's unique chassis), and secure mounting. Professional installation ensures optimal performance and prevents exhaust leaks.

Will the outback exhaust help lower my EGTs (Exhaust Gas Temperatures)?

Yes, the improved exhaust flow and reduced backpressure typically result in lower EGTs, particularly under load. This is especially beneficial for Troopys that are often heavily loaded with passengers, equipment, and gear. Many customers report EGT reductions of 50-100°C when fully loaded or climbing hills—critical for engine longevity in demanding applications.

Is the Outback exhaust suitable for mine site work and remote touring?

Absolutely. The Outback exhaust is specifically engineered for the demands of mine site operations, remote touring, and expedition use. The improved power and torque delivery makes driving a loaded Troopy significantly easier, while the stainless steel construction and robust mounting system handle corrugated roads, water crossings, and extreme conditions with ease. It's the ideal upgrade for serious 78 Series Troopy owners and operators.

Do you ship Australia-wide and internationally?

Yes, Outback Exhausts offer nationwide delivery across Australia. Due to the size and weight of this system (23kg), shipping costs vary by location. Metro areas typically receive orders within 3-7 business days, while regional and remote areas may take 7-14 business days.
