A muffler-free 3in DPF-back, the MPI Automotive MKIZ0043 opens the rear of the system for an unrestricted note. It's listed to fit the Isuzu MU-X 3.0L from July 2021 (MY21) through 2025, picking up behind the diesel particulate filter.

What does a DPF-back cover?

A DPF-back replaces the exhaust from behind the diesel particulate filter rearward, leaving the DPF and the emissions hardware upstream untouched. On the MU-X's 3.0L turbo-diesel the MKIZ0043 runs a 3in bore and deletes the rear muffler, so it opens the note without disturbing the particulate filter. It's the engine-end-light, free-flowing rear half of the system.

Why the muffler delete?

Running without a rear muffler keeps the 3in path as open as the DPF-back design allows, so the note is more vocal than a muffled section. For an MU-X owner who wants the diesel to breathe a little freer at the back, that's the appeal — a single, clean section behind the DPF.

Is it road legal?

As a DPF-back, the MKIZ0043 leaves the diesel particulate filter and upstream emissions equipment in place — it doesn't touch the DPF. Deleting the muffler changes the note, so confirm noise levels and any state requirements with the workshop before fitting.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this MPI Automotive 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 $998.03.

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

Common questions

Does the MKIZ0043 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.
Does it have a muffler?
No. It's the muffler-free version, so the rear runs open for a more vocal note. We don't publish decibel figures.
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.
