MPI Automotive Isuzu D-Max Mazda BT50 2021 Onwards, Centre Muffler.
Category: Mufflers and resonators


The MPI Automotive MBM617MF is a centre muffler listed to fit the Isuzu D-Max and Mazda BT-50 from 2021 onwards. As the mid-system silencer for the shared current-generation ute platform, it changes the middle of the exhaust rather than the rear box.
The centre muffler is the mid-system silencer, working between the front section and the rear box. Replacing it shapes the note from the middle of the exhaust without touching the tailpipe. On the current D-Max and BT-50 the MBM617MF takes that centre position, so it's a mid-section change rather than a rear-only swap.
From 2021 the Isuzu D-Max and Mazda BT-50 share the same platform, so a single centre muffler covers both. As a chambered box it quietens by absorption and reflection, keeping the diesel's note controlled. The supplier hasn't published a bore figure for this listing, so we confirm the pipe size on the bench rather than guess it.
It's listed to fit the Isuzu D-Max and Mazda BT-50 from 2021 onwards as a centre muffler. Confirm your exact year and build with the workshop before ordering — fitment data can be imperfect, and we'll check the centre-section dimensions against your ute.
