Frequently Asked Questions

How does the outback exhaust sound?

The outback exhaust produces a deep, refined tone that's noticeably sportier than stock without being overly loud. It enhances the diesel character while remaining comfortable for daily driving, highway cruising, and work use. You'll hear a satisfying growl under acceleration with minimal noise at cruise.

What's included in the 5-year warranty?

The Outback Exhausts 5-year warranty covers manufacturing defects, material failure, and weld integrity under normal use. It does not cover damage from accidents, improper installation, modifications, or extreme abuse.

Do I need to tune my vehicle after installing the outback exhaust?

No tune is required. The outback exhaust works perfectly with the factory ECU calibration and will provide noticeable improvements on its own. However, many customers choose to add a tune later to maximize the performance benefits of improved exhaust flow, especially for towing and heavy-duty use.

Can I install the outback exhausts myself?

Yes, the Outback exhausts is a bolt-on system designed for DIY installation. You'll need basic hand tools, jack stands or a hoist, and 2-3 hours. However, professional installation is recommended if you're not confident working under your vehicle.

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 to the rear, including the catalytic converter. A DPF-back system only replaces the exhaust from the DPF outlet back. The 2011-2015 Thai Built Navara D40 models did not have DPF systems, so turbo-back is the appropriate configuration for maximum performance gains. This system includes a high-flow cat and muffler / resonator.

What's the difference between Thai Built and Spanish Built D40 Navara?

The Thai Built D40 Navara (2011-2015) features the 126kW version of the 2.5L YD25 engine, while the Spanish Built models had the higher output 140kW version. This exhaust is specifically designed for the Thai Built variant. Please contact us if you need an exhaust for a Spanish Built D40 - we have specific systems for different D40 variants.

Does the outback exhaust improve fuel economy?

Yes, many customers report improved fuel efficiency after installing this exhaust, particularly during highway driving and when maintaining steady speeds. The reduced back pressure allows the engine to work more efficiently. However, actual fuel savings will vary based on driving style, load, and conditions.

Will the outback exhaust rust?

Our 409 stainless steel construction provides excellent corrosion resistance for Australian conditions. While 409 stainless may develop some surface discoloration over time (especially in coastal or high-humidity areas), it will not rust through like mild steel exhausts. This is why we can confidently offer a 5-year warranty.

Will the Outback fit other D40 models or earlier/later years?

The outback exhaust system is specifically designed for the Thai Built Nissan Navara D40 (June 2011-2015) with the 2.5L YD25 126kW engine. It will not fit Spanish Built D40 models, earlier D40 models (2005-2011), or D23 models, which have different exhaust configurations. Please contact us if you need an exhaust for a different Navara model - we have specific systems for various Navara generations and variants.
