Frequently Asked Questions

Will this outback exhaust fit my Isuzu DMAX?

This outback exhaust is specifically designed for Isuzu DMAX models with the 3.0L 4JJ1-TC turbo diesel engine manufactured between July 2012 and 2016. Please verify your vehicle's engine code and manufacturing date before ordering.

How difficult is the installation of the Outback Exhausts system? Can I fit it myself?

This outback exhaust is a bolt-on system designed for straightforward installation. If you're mechanically inclined with basic tools and a vehicle hoist or jack stands, you can install it yourself in 2-3 hours. However, we recommend professional installation to ensure proper fitment and optimal performance. All mounting hardware are included.

What performance gains can I expect from an Outback Exhaust?

Most customers report noticeable improvements in throttle response, reduced turbo lag, lower exhaust gas temperatures (EGTs), and modest fuel economy gains (typically 0.5-1.5L/100km depending on driving conditions). You'll also experience better towing performance and a more responsive engine across the rev range.

How loud is the Outback exhaust compared to stock?

Our 3" turbo back system produces a deeper, more aggressive tone than the factory exhaust, but it's not excessively loud. It's refined enough for comfortable daily driving and long highway trips, while still giving your DMAX a purposeful diesel sound under acceleration. It's the perfect balance for a working 4x4.

What's covered under the 5-year warranty?

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

Will the outback exhaust rust or corrode?

Outback exhaust systems are constructed from premium stainless steel specifically chosen for its superior corrosion resistance. This material is ideal for Australian conditions including coastal environments, outback dust, and harsh weather. With proper care, your exhaust will maintain its appearance and performance for many years.
