Frequently Asked Questions

Will this outback exhaust fit my Holden Trailblazer?

This outback exhaust system is designed specifically for Holden Trailblazer 2.8L LWN Duramax diesel models from 2017 to 2020. If you're unsure about fitment for your specific vehicle, contact us with your VIN or build date and we'll confirm compatibility.

What performance improvements can I expect from an Outback exhaust?

The 3" mandrel bent design improves exhaust flow compared to the factory system, resulting in better throttle response, potential fuel efficiency gains, reduced exhaust gas temperatures, and a deeper, more aggressive exhaust note without being overly loud.

How difficult is the installation of the Outback Exhaust system?

This outback exhaust is a bolt-on DPF back system designed for straightforward installation. All necessary gaskets (excluding turbo gasket)  and hardware are included. Most customers with basic mechanical skills and tools can install it at home, or your local mechanic can typically fit it in 1-2 hours.

What's covered under the 5-year warranty?

The Outback Exhaust 5-year warranty covers manufacturing defects and material failures under normal use conditions. This demonstrates our confidence in the quality and durability of our Australian-made stainless steel exhaust systems.

Will installing this void my vehicle warranty?

Installing an Outback Exhausts aftermarket exhaust should not void your vehicle warranty under Australian Consumer Law, provided the exhaust is ADR compliant (which this is) and properly installed. However, we recommend checking with your dealer if you have specific warranty concerns.

What's the difference between DPF back and turbo back?

A DPF back system replaces the exhaust from the DPF (Diesel Particulate Filter) to the rear of the vehicle, while a turbo back system replaces everything from the turbo outlet.
