Isuzu MU-X July 2021(MY21) - 2025 3.0L 3in DPF Back Without Muffler.
Category: Mufflers and resonators


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.
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.
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.
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.
