Isuzu D-Max Jan 2017 - 2020 3.0L TURBO BACK WITH CAT & WITHOUT MUFFLER.
Category: Mufflers and resonators


Cat retained, muffler deleted — the MPI Automotive SSMKIZ0027 is a turbo-back for the Isuzu D-Max 3.0L (2017–2020) that keeps the factory converter while opening the back of the system. It's the louder build that still runs the cat.
This is the defining trade-off of the SSMKIZ0027. The catalytic converter stays in the path, so the emissions component that usually governs road compliance on a diesel ute is retained, but the rear muffler is removed so the back half runs straight through. The 3.0L gains a fuller, harder note than a mufflered turbo-back while keeping the converter — the middle ground between a quiet system and a full cat-delete.
A turbo-back replaces the exhaust from the turbo outlet rearward, the full run on this D-Max rather than a tailpipe-only change. That's the longer span where a 3.0L diesel tends to free up. On the SSMKIZ0027 the converter sits in that run, with the muffler removed behind it.
It's listed to fit the 2017–2020 3.0L Isuzu D-Max, so the turbo flange and routing are specific to that build. Because it retains the catalytic converter, the factory emissions equipment stays in place; deleting the muffler does raise the note, which can bear on noise compliance, so confirm the exact build and any state requirements with the workshop before fitting.
