Mazda BT50 DPF 3.2L WITHOUT CAT & WITH HOTDOG (SSMKMA0019) Fits MAZDA. Fast shipping, warranty included.
Category: Mufflers and resonators


The MPI Automotive SSMKMA0019 is the cat-delete, hotdog build for the DPF Mazda BT-50 3.2L. Removing the catalytic converter while keeping a hotdog resonator is its defining combination — freer flow than the with-cat version, with a compact resonator still managing the note.
On the DPF BT-50 3.2L this build removes the catalytic converter, so the converter restriction is gone from the run. The hotdog stays in place to keep the note in check, which is why the SSMKMA0019 flows more freely than its with-cat sibling but isn't a bare straight pipe. The trade-off is honest and it's a compliance one — covered below.
Because the SSMKMA0019 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 hotdog manages drone but does not change that status. This is an off-road or competition build, not for a registered road vehicle.
A hotdog is a small straight-through resonator that cuts the harshest drone without the bulk of a muffler. Pairing it with the cat-delete gives a tidier note than a bare delete while keeping flow high — a sensible middle ground for an off-road BT-50.
Oak Flats Muffler Men supplies and fits this section for the DPF 3.2L BT-50 at our Illawarra workshop. It's listed to fit the Mazda BT-50; we'll confirm the build, go through the off-road-only status, and check the hotdog clearance and joins first.
