Mazda BT50 2021 ON 1.9L DPF BACK (SKU: MKMA0028) Engineered. Quality guaranteed.
Category: Complete exhaust systems


The MPI Automotive MKMA0028 is a DPF-back exhaust listed to fit the Mazda BT-50 1.9L from 2021. It replaces the pipework behind the diesel particulate filter and keeps the factory DPF.
This MKMA0028 is matched to the Mazda BT-50 with the smaller 1.9L diesel from 2021. The 1.9L is the key callout — it's a different engine to the 3.0L BT-50 and the rear routing is matched to it. It's a DPF-back, so it covers the section from behind the diesel particulate filter to the tailpipe. The supplier hasn't published the bore, material or muffler arrangement, so those aren't quoted. The listed RRP is $1124.94.
No. A DPF-back starts behind the diesel particulate filter, so the factory DPF is left untouched and only the run after it is replaced. That keeps the emissions filter — the compliance sticking point on a diesel ute — exactly where the BT-50 left the factory, while changing the rear pipework.
It's listed to fit the 1.9L Mazda BT-50 from 2021. Engine size matters here, so send us your exact build and we'll confirm it's the 1.9L DPF-back before ordering.
