Mazda BT50 DPF 3.2L WITHOUT CAT & WITH HOTDOG (SKU: MKMA0019) Engineered. Quality guaranteed.
Category: Mufflers and resonators


The MPI Automotive MKMA0019 deletes the catalytic converter and tunes the system with a hotdog. Listed to fit the Mazda BT-50 DPF 3.2L, the cat-delete makes it off-road only, while the hotdog keeps drone in check on this DPF-generation ute.
Because the MKMA0019 deletes the catalytic converter on a DPF-equipped system, it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road use only. Removing the cat takes out emissions hardware the BT-50 needs to be road-legal — we state that plainly so you can weigh it before ordering.
Rather than a full muffler, this build uses a hotdog — a compact straight-through resonator. It cuts resonance and drone with minimal restriction, so with the cat gone the DPF BT-50 keeps a free-breathing path and a hard, present note while the hotdog stops the worst of the cabin boom. It sits between the fully stripped, no-muffler section and a quieter muffled build.
It's listed to fit the Mazda BT-50 DPF with the 3.2L engine. DPF routing is specific, so confirm your exact build and year with the workshop before ordering, and factor in the off-road-only status. Listed fitment is a guide, not a guarantee.
Oak Flats Muffler Men supplies and fits the MKMA0019 in-house. We confirm the section works with the DPF setup, position the hotdog, set the hangers, and talk through the off-road-only implications before sign-off. RRP is AUD 1486.34; send your BT-50 DPF 3.2L's spec and we'll book the bay.
