Yes — with no muffler or resonator behind the cat it is the most open and loudest of the with-cat builds. We can talk you through quieter rear options on the same platform.

Does it keep the catalytic converter?

Yes — this is the with-cat turbo-back, so the factory catalytic converter stays in place. Only the rear is left open.

Vehicle fitment: Isuzu
Stock status: In stock at supplier

An open rear with the cat left in place — the MPI Automotive SSMKIZ0041 is the loudest with-cat turbo-back for the Isuzu MU-X 3.0L (2017–2025). It runs no muffler or resonator behind the catalytic converter, so the factory emissions hardware stays put while the rear section is left uncorked.

The loudest with-cat option

What sets this SKU apart is the empty rear section: no muffler, no resonator behind the cat, so it is the freest-flowing and hardest-sounding of the with-cat builds. There is no silencing box to settle the note and no drone control on the highway. It suits a driver chasing maximum noise and minimum restriction at the rear while keeping the cat for emissions hardware.

Cat retained but not automatically compliant

The SSMKIZ0041 keeps the factory catalytic converter, leaving the emissions hardware the MU-X left the factory with in place. That is the usual focus on a modern diesel ute, but keeping the cat does not by itself make the system compliant — the open rear changes the noise, so confirm the exact build and any state requirements with the workshop before fitting.

Where the turbo-back sits on the DPF MU-X

A turbo-back replaces the run from the turbo outlet rearward, a longer span than a cat-back, and on the 2017–2025 MU-X it covers the DPF-back plumbing around the factory diesel particulate filter location. MPI Automotive lists the SSMKIZ0041 at $2644.16, generally ordered in to suit your build.
