MPI Automotive Mazda BT50, DPF Back 3in Centre Hotdog.
Category: Mufflers and resonators


The MPI Automotive MBM572PHD-DPFBACK is a 3in DPF-back centre hotdog listed to fit the Mazda BT-50. It's a compact straight-through resonator for the section behind the diesel particulate filter — the part that tidies the note on a DPF-back run rather than a full muffler.
DPF-back means the system runs from behind the diesel particulate filter rearward, leaving the DPF in place. This part is the 3in centre hotdog for that run — a straight-through resonator with a perforated core and packing, no baffles. It settles the note without choking the flow, sitting more open than a chambered centre muffler would on the BT-50's DPF-back section.
Because a hotdog flows straight through, it takes the edge off the diesel drone while keeping the 3in run open. That makes it the leaner, more open centre choice — it tidies rather than heavily quietens. On a DPF-back BT-50 it's the centre section for an owner who wants the note cleaned up without losing flow.
It's listed to fit the Mazda BT-50. The supplier doesn't publish the engine, series or model-year for this listing, so send your exact build and we'll confirm the DPF-back fitment and routing before ordering. Detailed specs beyond the 3in bore aren't published, and we'll confirm them with you.
