Frequently Asked Questions

Will the outback exhaust improve performance on my Navara D40?

Yes, the 3" mandrel bent turbo-back design reduces exhaust back pressure significantly, resulting in improved throttle response, better power delivery, and enhanced fuel efficiency. Most customers report noticeable improvements in drivability, especially when towing, loaded, or climbing hills. The 2.5L YD25 140kW engine responds particularly well to the complete turbo-back system.

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.

How long does shipping take?

Most orders ship within 1-2 business days. Delivery times vary by location: metro areas typically receive orders within 3-5 business days, while regional areas may take 5-7 business days.

Do you ship internationally?

Yes, Outback Exhausts ships internationally to select countries. International shipping costs and delivery times vary by destination. Enter your country and postcode at checkout for accurate freight quotes. Please note that international customers are responsible for any customs duties, taxes, or import fees charged by their country. Contact us for specific international shipping enquiries.

Can I install the outback exhausts myself?

Yes, the outback exhaust is a bolt-on system designed for DIY installation. You'll need basic hand tools, jack stands or a hoist, and 2-3 hours. We provide detailed instructions. 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 Spanish 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 Spanish Built and Thai Built D40 Navara?

The Spanish Built D40 Navara (2011-2015) features the higher output 140kW version of the 2.5L YD25 engine, compared to the Thai Built models which had different power outputs. This exhaust is specifically designed for the Spanish Built variant. Please contact us if you need an exhaust for a Thai 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.

Can I use the outback exhaust for towing?

Absolutely! The outback exhaust is ideal for towing applications. The improved exhaust flow reduces back pressure, which helps the engine breathe better under load. Many customers specifically upgrade their exhaust to improve towing performance, and the Navara D40's 2.5L YD25 140kW engine responds particularly well to the reduced restriction when pulling heavy loads up to the Navara's 3.5-tonne towing capacity.

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

The outback exhaust system is specifically designed for the Spanish Built Nissan Navara D40 (September 2011-2015) with the 2.5L YD25 140kW engine. It will not fit Thai 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.
