Frequently Asked Questions

Q: Will this outback exhaust fit my Isuzu DMAX?
A: This outback exhaust system is designed specifically for Isuzu DMAX 3.0L 4JJ1 engines from 2017 to August 2020. Please verify your vehicle's engine code and year before ordering. Contact us if you're unsure about fitment.

Q: What's the difference between DPF-back and turbo-back exhausts?
A: A DPF-back system replaces the exhaust from the DPF to the rear. A turbo-back system replaces everything from the turbo.

Q: How difficult is the installation of the Outback Exhausts system?
A: This outback exhaust is a bolt-on system designed as a direct factory replacement. Most customers with basic mechanical skills can install it in 2-3 hours. We recommend professional installation if you're not confident working under your vehicle.

Q: Will this outback exhaust improve performance or fuel economy?
A: The mandrel-bent design and larger 3" diameter reduce exhaust back pressure, which can result in improved throttle response and potentially modest gains in fuel efficiency. Results vary based on driving conditions.

Q: What material is the outback exhaust made from?
A: Premium 409 grade stainless steel construction ensures excellent corrosion resistance and longevity, especially important for Australian conditions including coastal environments and off-road use.

Q: What does the 5-year warranty cover?
A: The Outback Exhaust 5-year warranty covers manufacturing defects and material failures under normal use. It does not cover damage from accidents, improper installation, or modifications.

Q: Do you ship worldwide?
A: Yes, Outback exhausts ships to all Australian states and territories. Shipping costs are calculated at checkout based on your location. We do ship internationally.

Q: Is the outback exhaust louder than stock?
A: You may notice a slightly deeper note compared to the factory exhaust, but it remains relatively quiet and suitable for daily driving. It's not an aggressive or loud system.
