Isuzu D-Max Mazda BT50 2021 Onwards, Centre Muffler (SSMBM617MF) fits selected vehicle applications.
Category: Mufflers and resonators


The MPI Automotive SSMBM617MF is a centre muffler for the 2021-onwards Isuzu D-Max and its Mazda BT-50 twin — the mid-system silencer for the current-generation shared diesel ute platform. The supplier hasn't published a bore for this listing.
The centre muffler sits in the middle of the system, ahead of the rear silencer, and it's where a lot of low-frequency drone gets knocked down before it can boom through the cab. On a 2021-onwards D-Max or BT-50 that's used for both work and family duty, getting the mid silencing right keeps the diesel civil on a long drive. It quietens by absorption and reflection through its chambers.
From 2021 the Isuzu D-Max and Mazda BT-50 share a platform and exhaust layout, so a single centre muffler covers both. That's why this part is listed for Isuzu and Mazda alike. The pipe diameter for this listing isn't published by the supplier, so confirm it against your system rather than assuming a size.
It's listed to fit the Isuzu D-Max and Mazda BT-50 from 2021 onwards. Confirm your exact model year and the rest of your system with the workshop before ordering, especially the pipe diameter since it isn't published here.
