MPI Automotive Mazda BT50 B32P 3.2L Without Cat & Without Muffler.
Category: Mufflers and resonators


The MPI Automotive SSMKMA0027 is the no-cat, no-muffler build for the B32P Mazda BT-50 3.2L — the most stripped-back configuration in the family. With both the catalytic converter and the muffler deleted, it is the freest-flowing and hardest-sounding of the B32P options.
Removing the muffler leaves nothing to absorb the gas pulse, so the note is direct and loud; removing the cat takes out the converter restriction as well. Together they make the SSMKMA0027 the least-restricted version for the B32P 3.2L, but also the one with the most consequences for compliance. There's no sound figure to quote — the character is plainly the most aggressive of the variants.
Because this build deletes the catalytic converter on the BT-50's diesel system, it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road use only. The muffler-delete also affects noise compliance. This is the configuration to choose only for off-road, competition or property use, not a registered road vehicle.
On a diesel ute this layout is aimed at owners running the vehicle off-road who want maximum flow and the simplest, lightest back-half. It is honestly a niche build — for a road-driven BT-50 the with-cat or muffler-equipped versions are the relevant ones.
Oak Flats Muffler Men supplies and fits this section for the B32P 3.2L at our Illawarra workshop. It's listed to fit the BT-50 B32P; we'll confirm the build, talk through the off-road-only status, and check the joins and hangers before fitting.
