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.

What does deleting both the cat and muffler change?

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.

Is it road legal?

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.

What's a cat-and-muffler delete for?

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.

How do we handle it in the Illawarra?

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.

No. It deletes the catalytic converter, so it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road use only.
Why is it the loudest BT-50 option?
It runs without a muffler and without a cat, so nothing is absorbing or restricting the note — it's the most direct of the configurations.
Will it fit my BT-50?
It's listed to fit the B32P Mazda BT-50 3.2L. Confirm your exact build with the workshop first.
