The stainless build of this DPF-back, the MPI Automotive SSMKIZ0043 leans on corrosion life as its point of difference. This 3in muffler-free DPF-back is listed to fit the Isuzu MU-X 3.0L from July 2021 (MY21) through 2025, picking up behind the diesel particulate filter.

Why the stainless construction?

Stainless resists rust and surface corrosion far better than mild or aluminised steel, which matters on a 4x4 that sees mud, salt and water crossings. For an MU-X owner planning to keep the truck a while, the stainless SSMKIZ0043 is the longer-life choice in this DPF-back family — it's built to hold up under exposure where a coated steel section might eventually surface-rust.

What does the 3in DPF-back cover?

A DPF-back replaces the exhaust from behind the diesel particulate filter rearward, leaving the DPF and upstream emissions hardware in place. The SSMKIZ0043 runs a 3in bore and deletes the rear muffler, so it opens the note without disturbing the particulate filter.

Is it road legal?

As a DPF-back, the SSMKIZ0043 leaves the diesel particulate filter and upstream emissions equipment untouched — it doesn't remove the DPF. Deleting the muffler does change the note, so confirm noise levels and any state requirements with the workshop before fitting.

What's involved in fitting it in the Illawarra?

Oak Flats Muffler Men supplies and fits this MPI Automotive stainless DPF-back in-house across the Illawarra. We confirm the connection behind the DPF, check hanger points on the 3in run and the listed MU-X fitment, then book the bay. The RRP is $1,378.83.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.

Common questions

What makes the SSMKIZ0043 different?
It's the stainless version, chosen for its corrosion life on a 4x4 that sees mud, salt and water — the longer-life option in this DPF-back family.
Does it remove the DPF?
No. It's a DPF-back, so it starts behind the diesel particulate filter and leaves the DPF and upstream emissions hardware in place.
Will it fit my MU-X?
It's listed to fit the Isuzu MU-X 3.0L from July 2021 (MY21) to 2025. Confirm your exact build with the workshop first.
