Mazda BT50 2021 ON 1.9L DPF BACK (SSMKMA0028) Fits MAZDA. Fast shipping, warranty included.
Category: Complete exhaust systems


The MPI Automotive SSMKMA0028 is a DPF-back exhaust listed to fit the Mazda BT-50 with the 1.9L diesel from 2021. It replaces the run from the diesel particulate filter back, carrying a known RRP of $1,609.81.
The SSMKMA0028 is a DPF-back system, meaning it replaces the exhaust from the diesel particulate filter rearward and leaves the factory DPF in place. For the 1.9L BT-50 from 2021 that is the common upgrade path — it reworks the section behind the emissions hardware rather than touching the filter itself. Diameter, material and muffler configuration are not published by the supplier for this listing, so we confirm those when matching it to your ute.
A DPF-back exhaust starts at the outlet of the diesel particulate filter and runs to the tailpipe. Because it keeps the DPF, it leaves that emissions hardware as the factory fitted it while changing the pipework downstream. It is a more contained change than a turbo-back, and on a smaller-capacity diesel like the BT-50's 1.9L it focuses on the rear section of the system.
It is listed to fit the Mazda BT-50 1.9L from 2021; confirm the exact build and variant with the workshop before ordering. BT-50 specs vary across the range, so we check your vehicle against the part rather than assume it bolts straight on.
