Installation

This is a bolt-on replacement exhaust system designed for straightforward installation. Most customers with basic mechanical skills and tools can install this system in 2-3 hours. Professional installation is recommended for best results. No cutting or welding required - simply remove the factory exhaust from the catalytic converter back and bolt this system in place.

Performance Benefits

The 3" mandrel bent design reduces exhaust back pressure compared to the restrictive factory system. You'll experience improved throttle response, better power delivery throughout the rev range, and enhanced fuel efficiency. The Navara STX550's 3.0L V6 turbo diesel engine particularly benefits from the improved exhaust flow, with noticeable gains when towing, loaded, or climbing. You'll enjoy that distinctive V6 exhaust note while maintaining ADR compliance.

Frequently Asked Questions

 

Will the outback exhaust improve performance on my Navara STX550?

Yes, the 3" mandrel bent design reduces exhaust back pressure, 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 3.0L V6 engine responds particularly well to improved exhaust flow.

How does the outback exhaust sound?

The outback exhaust produces a deep, refined V6 tone that's noticeably sportier than stock without being overly loud. It enhances the V6 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 cat-back and turbo-back?

A cat-back system (like this one) replaces the exhaust from the catalytic converter outlet to the rear, retaining the factory catalytic converter and front pipe. A turbo-back system replaces everything from the turbo outlet, including the catalytic converter. 

Will this fit other Navara models or the D40?

This system is specifically designed for the Nissan Navara STX550 (2010-2015) with the 3.0L V6 engine. While the STX550 is based on the D40 platform, this exhaust is specifically engineered for the V6 variant. Please contact us if you need an exhaust for a different Navara model - we have specific systems for various Navara generations and engines.

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 STX550's 3.0L V6 engine responds particularly well to the reduced restriction when pulling heavy loads up to the Navara's 3.5-tonne towing capacity.

What is the V9X engine?

The V9X is Nissan's 3.0L V6 turbo diesel engine used in the Navara STX550 (2010-2015). This premium engine delivers strong performance and torque, making it ideal for towing and heavy-duty use. The V9X responds exceptionally well to exhaust upgrades, with noticeable improvements in power delivery and efficiency.
