Frequently Asked Questions

Is the outback exhaust specifically designed for the DTS turbo upgrade?

Yes, the outback exhaust is specifically engineered for 105 Series Landcruisers with the DTS turbo upgrade. The 3" diameter and optimized flow characteristics are designed to handle the increased boost and exhaust flow from the DTS turbo, ensuring you get maximum performance gains from your turbo upgrade investment.

Will the outback exhaust fit my 105 Series with factory turbo?

The outback exhaust is optimized for the DTS turbo upgrade. If you have a factory turbo 105 Series (1HDFTV), we recommend our factory turbo-specific exhaust system for best fitment and performance. Please contact us to confirm the right exhaust for your specific turbo setup.

How difficult is the installation of the outback exhausts system?

The outback exhaust is a bolt-on system designed for straightforward installation. Most mechanically-inclined owners can install it with basic hand tools in 2-4 hours. We include all necessary hardware and gaskets. Professional installation is recommended if you're not comfortable working under your vehicle or don't have access to a hoist.

What performance gains can I expect with my DTS turbo?

Combined with your DTS turbo upgrade, you'll experience substantial performance improvements including significantly improved throttle response, faster turbo spool, and major torque gains throughout the rev range. Most customers report EGT reductions of 50-100°C under load, which is critical for engine longevity with increased boost. The exhaust allows your DTS turbo to work at peak efficiency, maximizing your turbo upgrade investment.

Will the outback exhaust be too loud for long-distance touring?

No. Despite the increased flow capacity, our exhaust systems are designed to deliver a deep, refined note without excessive cabin noise. You'll hear a more aggressive note under boost and acceleration - befitting your upgraded turbo - but it remains comfortable for long-distance touring and daily driving. 

What does the 5-year warranty cover?

The Outback Exhaust 5-year warranty covers manufacturing defects and material failures under normal use, including with turbo upgrades. This includes weld integrity, material corrosion, and structural failures. The warranty does not cover damage from accidents, improper installation, modifications, or extreme off-road impacts.

How does this help with EGT management on my DTS turbo?

The 3" mandrel-bent design significantly reduces backpressure, allowing exhaust gases to exit more efficiently. This results in substantially lower exhaust gas temperatures - typically 50-100°C cooler under load. Lower EGTs mean your engine runs cooler, safer, and more efficiently, which is especially important with the increased boost from your DTS turbo upgrade.

Do you ship Australia-wide?

Yes, Outback Exhausts offer nationwide delivery across Australia. Shipping is calculated at checkout based on your location. For remote areas or international shipping, please contact us for a freight quote. Most metro areas receive delivery within 3-5 business days.

Can I use the outback exhaust for serious off-road and water crossings?

Absolutely. Our stainless steel construction is specifically chosen for its corrosion resistance in harsh conditions including water crossings, salt air, coastal environments, and muddy terrain. The system is built to handle the rigors of serious 4x4 touring, remote area travel, and the increased heat from your DTS turbo upgrade in the toughest Australian conditions.

Will the outback exhaust help with towing performance?

Yes, dramatically. Combined with your DTS turbo upgrade, the improved exhaust flow reduces backpressure and significantly lowers EGTs, allowing your engine to work more efficiently under heavy load. Customers regularly report exceptional hill-climbing ability, reduced gear changes when towing, and much more confidence when pulling heavy caravans or trailers - especially in hot weather or mountainous terrain.

What's the difference between this and the factory turbo exhaust?

The outback exhaust is specifically optimized for the DTS turbo upgrade, with flow characteristics designed to handle the increased boost and exhaust volume. The DTS turbo produces significantly more exhaust flow than the factory turbo, and this exhaust is engineered to maximize that performance potential while maintaining ADR compliance.
