Frequently Asked Questions.

How does the outback exhaust sound?

The outback exhaust produces a deep, refined tone that enhances the distinctive 6-cylinder diesel character. It's noticeably sportier than stock without being overly loud. You'll hear a satisfying growl under acceleration with minimal noise at cruise - perfect for daily driving, touring, and off-road adventures.

What's included in the 5-year warranty?

The Outback Exhaust 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 off-road 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 setup and will provide noticeable improvements on its own. However, many Patrol owners choose to add other modifications later to maximize the performance benefits of improved exhaust flow.

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.

Can I install the outback 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. However, professional installation is recommended if you're not confident working under your vehicle.

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

The outback exhaust system is specifically designed for naturally aspirated (non-turbo) TD42 engines. It includes an extractor instead of a turbo manifold. If you have a turbocharged TD42, you'll need a different exhaust system designed for turbo applications. Please contact us if you're unsure which system you need.

Will the outback exhaust fit other Patrol models or body styles?

The outback exhaust system is specifically designed for the Nissan Patrol GQ Wagon (1987-1997) with the 4.2L TD42 naturally aspirated engine. It will not fit turbocharged TD42 models, other body styles like the Ute, or other Patrol generations like GU. Please contact us if you need an exhaust for a different Patrol model - we have specific systems for various Patrol configurations.

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 and improved exhaust scavenging from the extractor allow 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.
