A 3in 304-stainless DPF-back, the Exhaust Systems Australia TOYOTA-PRADO-GUN150R-2-8L-TD-3-STAINLESS-DPF-BACK-MUFFLER-ONLY-EXHAUST-SYSTEM is listed to fit the GUN150R Prado 2.8L turbo-diesel. As a DPF-back it runs from the diesel particulate filter rearward — so it leaves the DPF in place and renews the system behind it in 3in.
What does a DPF-back cover on the Prado?
A DPF-back replaces the exhaust from the diesel particulate filter rearward, so the DPF and the emissions hardware ahead of it stay as the Prado left the factory. Stepping the section behind the DPF up to 3in opens the flow on the 2.8L turbo-diesel where the factory system is tighter. This is the muffler-only version, meaning it carries a muffler rather than a straight-through rear for a controlled note.
Why 304 stainless?
The GUN150R Prado is a touring 4x4 that sees long highway runs, dust and the occasional crossing, and the rear of the system runs hot. A 304-stainless DPF-back resists corrosion and the heat-bluing of aluminised tube far better over a long ownership, which is the case for the stainless build on a vehicle you keep and travel in.
Is it road legal?
Because it's a DPF-back, the diesel particulate filter stays in place — the emissions component that matters most on a modern diesel. The supplier doesn't publish a compliance statement, so confirm the exact build and any NSW registration requirements with the workshop before fitting.
