Frequently Asked Questions

 

How does this exhaust sound?

The exhaust produces a deep, refined tone that enhances the distinctive 6-cylinder petrol 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.

Do you ship internationally?

Yes! We ship our exhaust systems internationally to select countries. International orders may require freight quoting depending on destination and system size. Contact us for a shipping quote to your location, and we'll provide customs and duties information specific to your country.

What's included in the 5-year warranty?

Our 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.

Is professional installation required?

While this is a bolt-on system designed for straightforward installation, we recommend professional fitting by a qualified mechanic or exhaust specialist to ensure proper alignment, secure mounting, and optimal performance.

Will this exhaust improve performance?

Yes, the mandrel-bent design reduces exhaust restriction compared to factory systems, allowing for improved exhaust flow. This can result in better throttle response and potentially modest power gains, while also enhancing exhaust tone.

How long does delivery take within Australia?

We offer nationwide delivery across Australia. Delivery times vary by location, with metro areas typically receiving orders within 3-7 business days. Remote locations may take longer.

Will this fit other Patrol models or body styles?

This system is specifically designed for the Nissan Patrol GU/Y61 Wagon ( 1997 onwards ) with the 4.5L TB45 petrol engine. It will not fit other body styles like the Ute, 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 this 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.
