Isuzu MU-X Jan 2017-2025 3.0L DPF Turbo Back Without Cat & Without Muffler (MKIZ0042) Fits ISUZU.
Category: Mufflers and resonators


The MPI Automotive MKIZ0042 is a turbo-back exhaust for the Isuzu MU-X 3.0L (2017–2025) built without the catalytic converter and with no muffler or resonator in the rear section. It is the engine-back upgrade for the DPF-equipped MU-X, replacing the run from the turbo outlet rearward rather than a tailpipe-only change.
This version is built without the catalytic converter, so it strips the emissions hardware out of the engine-back run. That sets it apart from the with-cat variant in the same family and gives the freest-flowing path through the section. Because it removes the catalytic converter, this configuration is not ADR 79/04 compliant for road registration in NSW and is sold for off-road and competition use only.
This SKU is built without a muffler or resonator in the rear section, so it is the most open configuration in the family — the freest-flowing and the loudest of the set. It suits owners chasing the hardest note and the least restriction, with the trade-off that it does the least to subdue the diesel's tone.
A turbo-back replaces the exhaust from the turbo outlet all the way back, a longer span than a cat-back and the section where a DPF-equipped diesel like the 3.0L MU-X tends to free up. On this 2017–2025 platform it covers the DPF-back plumbing, so the system is engineered around the factory diesel particulate filter location for this engine.
