Mazda BT50 DPF 3.2L WITHOUT CAT & WITHOUT MUFFLER (SSMKMA0020) Fits MAZDA. Fast shipping, warranty included.
Category: Mufflers and resonators


The MPI Automotive SSMKMA0020 is a DPF-back run for the 3.2L Mazda BT-50 that deletes the catalytic converter and runs without a muffler — the most free-flowing, least restrictive layout in this line. It is listed to fit the BT-50 3.2L.
This SSMKMA0020 picks up after the diesel particulate filter and replaces the section through to the tailpipe. With both the catalytic converter and the rear muffler left out, there is no chambered silencer or cat substrate in the gas path, so it is the openest version MPI Automotive offers for this engine. The trade is loudness and legality: with nothing absorbing or reflecting sound, the 3.2L note carries hard, and with no cat the emissions hardware the ute left the factory with is gone.
Because it removes the catalytic converter, it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road or competition use only. If you need a registrable BT-50 build, ask the workshop about the with-cat, with-muffler equivalents instead.
It is listed to fit the 3.2L BT-50; the year span and exact body are not pinned in the supplier record, so send your build and we will confirm the DPF location and clearances before ordering.
Oak Flats Muffler Men supplies and fits DPF-back systems like this across the Illawarra. We check the DPF flange, hanger points and tailpipe exit on your actual ute, then book the bay once fitment is confirmed.
