Frequently Asked Questions

Will the outback exhaust fit my KZN165R Hilux ute?

Yes, the outback exhaust is specifically designed for the Toyota Hilux KZN165R ute with the 3.0L 1KZ-TE turbo diesel engine (October 1999 - May 2004). It's a direct bolt-on fitment designed to work perfectly with your model.

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 2-3 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 from the Outback Exhaust system?

You'll notice significantly improved throttle response, better turbo spool, and increased torque throughout the rev range - particularly beneficial when towing trailers, boats, or carrying heavy loads. Most customers report lower exhaust gas temperatures (EGTs) by 60-90°C under load, which helps with engine longevity, especially when towing in hot conditions. Fuel economy often improves by 8-12% under highway cruising and towing conditions.

Will the outback exhaust be too loud?

No. Our resonated design delivers a deep, refined tone without excessive cabin noise. You'll hear a noticeable improvement over stock - a more purposeful note under acceleration - but it remains comfortable for long-distance driving, daily work use, and highway cruising. Many customers report less drone than the factory exhaust at highway speeds.

What does the 5-year warranty cover?

The Outback Exhaust 5-year warranty covers manufacturing defects and material failures under normal use. 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.

Do you ship Australia-wide?

Yes, Outback Exhaust 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.

Will the outback exhaust help with towing performance?

Yes, significantly. The improved exhaust flow reduces backpressure and lowers EGTs, allowing your engine to work more efficiently under load. Customers regularly report better hill-climbing ability, reduced gear changes when towing, and more confidence when pulling boats, trailers, or work equipment - especially in hot weather or mountainous terrain. This is one of the most popular upgrades for Hilux owners who tow regularly.

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

A turbo-back system (like this one) replaces the entire exhaust from the turbo outlet, providing maximum performance gains. A DPF-back system starts after the DPF and retains factory emissions equipment. Since your 1999-2004 1KZ-TE Hilux doesn't have a DPF, this turbo-back system is the complete solution for maximum performance.

Will the outback fit the newer KUN series Hilux?

No, the outback exhaust is specifically designed for the KZN165R model with the 3.0L 1KZ-TE engine (1999-2004). The newer KUN series (2005 onwards) with the 1KD-FTV engine has different exhaust routing. Please search for our Hilux KUN series specific exhaust systems or contact us for the correct fitment.
