Mazda BT50 DPF 3.2L WITH CAT & WITHOUT MUFFLER.
Category: Mufflers and resonators


The MPI Automotive SSMKMA0022 is a DPF-back section for the Mazda BT-50 3.2L that keeps the catalytic converter and runs without a muffler. The no-muffler layout leaves the 3.2L diesel freest-flowing at the rear.
The SSMKMA0022 runs the DPF-back section with no muffler, so there is no chambered can to quieten the tail — the freest-flowing of the BT-50 layouts and a harder note than a muffler-terminated version. It keeps the factory cat, which matters for the diesel's emissions hardware. There are no decibel figures published by the supplier, so we describe it by design rather than a number we cannot measure.
A DPF-back section on a diesel touches emissions hardware, so it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road use. Although it retains the cat, confirm your intended use and the exact configuration with the workshop before fitting — there is no softening of that on a road-driven vehicle, so this section suits off-road or competition use rather than a registered BT-50.
It is listed to fit the Mazda BT-50 3.2L. Series and years aren't published by the supplier, so this is a listed-to-fit guide rather than a guarantee — confirm your exact build with the workshop before ordering.
Oak Flats Muffler Men supplies and fits BT-50 DPF-back sections in-house across the Illawarra. We confirm the configuration matches your vehicle, check the no-muffler routing under the BT-50, and verify the listing against your build before booking.
