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.

Frequently Asked Questions

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 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.
