Frequently Asked Questions

Will the outback exhaust improve performance on my Patrol GU/Y61?

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 off-roading. The legendary 4.2L TD42 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 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 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 off-road abuse. 

Do I need to tune my vehicle after installing this 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 Patrol owners 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.

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. 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 1997-2015 Patrol GU/Y61 models did not have DPF systems, so turbo-back is the appropriate configuration for maximum performance gains. This system includes a high-flow cat for emissions compliance.

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

The outback exhaust system is specifically designed for the Nissan Patrol GU/Y61 Wagon (1997-2015) with the 4.2L TD42 engine. It will not fit other body styles like the Ute or Cab Chassis, or other Patrol generations like GQ. Please contact us if you need an exhaust for a different Patrol model - we have specific systems for various Patrol configurations.

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.
