This is the DPF-back, not a turbo-back: the MPI Automotive SSMKTY0413 is a 3in DPF-back system built without a muffler, listed to fit the Toyota Landcruiser GDJ76 wagon 2.8L turbo-diesel (2023-current). It picks up the exhaust after the diesel particulate filter rather than at the turbo, so it is the shorter, rear-section upgrade.
A DPF-back replaces the exhaust from the diesel particulate filter rearward, a shorter span than a turbo-back, which starts up at the turbo outlet. That leaves the DPF in place and reworks the section behind it. The SSMKTY0413 runs this rear section without a muffler, so there is no chambered silencer in the run and the back of the system flows more openly — the part you fit when you want to free up and open the tail of the GDJ76's exhaust while keeping the filter.
The supplier lists this DPF-back at a 3in bore, the size matched to a worked 2.8L diesel rather than a small stock engine. Running 3in from the DPF back keeps the bore consistent through the rear section, and with no muffler in the run the gas exits with the least restriction this system offers behind the filter.
This is a DPF-back that leaves the diesel particulate filter in place; the supplier does not publish a catalytic-converter detail for this part, so we don't claim one either way. A no-muffler system is louder than stock, and state noise and compliance rules apply to any modified exhaust, so confirm the exact build and any requirements with the workshop before fitting.
Oak Flats Muffler Men supplies and fits this DPF-back in-house across the Illawarra. We confirm it against your GDJ76 wagon, check the 3in pipework behind the filter and the no-muffler note, and book the bay once fitment is verified. It is a brought-in item; the listed recommended retail is $1,715.74, which we confirm with you along with availability before ordering.
