The Nissan Navara has been a mainstay of the Australian ute market across both the older D40 and current NP300 generations, and each has its own exhaust and DPF quirks. We stock DPF replacements for the D40 and NP300, alongside DPF-back and turbo-back exhaust systems for owners looking to improve flow and sound while keeping their Navara road-legal.

Does the D40 and NP300 Navara use the same DPF?

No – the D40 and NP300 Navara use different DPF units specific to their engine and emissions generation. Always confirm your exact model, build date and engine code before ordering a replacement DPF.

Why does my Navara keep getting a DPF warning light?

This is commonly linked to short, low-speed city driving that doesn't allow the DPF to reach the temperature needed for regeneration. Regular longer highway drives at higher RPM can help the filter burn off accumulated soot before it becomes a bigger issue.

Can I upgrade my Navara's exhaust without affecting its warranty or compliance?

A DPF-back or cat-back exhaust system retains the factory DPF and catalytic converter, which helps maintain emissions compliance. Warranty implications depend on your specific vehicle's terms, so it's worth checking with Nissan or your dealer if your vehicle is still under factory warranty.

What's the best exhaust upgrade for a Navara used for touring and towing?

A DPF-back or turbo-back system paired with a quality muffler is the most common setup for Navara owners chasing better flow and reduced exhaust gas temperatures under towing load, while keeping the vehicle road-legal.
