MPI Automotive Landcruiser GDJ76 Wagon, 2.8L TD, 2023-Current, 3in Turbo Back With Cat & Without Muffler.
Category: Mufflers and resonators


This variant keeps the cat but drops the muffler: the MPI Automotive SSMKTY0415 is a 3in turbo-back that retains the catalytic converter and runs without a rear silencer, listed to fit the Toyota Landcruiser GDJ76 wagon 2.8L turbo-diesel (2023-current). Emissions hardware stays, the back of the system opens up.
The SSMKTY0415 retains the factory catalytic converter — the component that matters most for compliance on a diesel — while leaving out the rear muffler. That makes it a freer-flowing, louder system than the muffled or hotdog builds, because the gas is not passing through a chambered silencer at the back, but the cat stays in place. It is the configuration for an owner who wants the open note without deleting the converter.
Because the SSMKTY0415 keeps the catalytic converter, it leaves the key emissions hardware the Landcruiser left the factory with in the system. A no-muffler system is louder, so state noise and registration rules still apply; confirm the exact build and any requirements with the workshop before fitting.
A turbo-back runs from the turbo outlet rearward, the full engine-back span. The supplier lists this at a 3in bore, sized to a worked 2.8L diesel. With the cat retained and no muffler at the back, the 3in pipe carries the gas through with the converter as the only major device in the path — the open-but-legal-emissions middle ground of the GDJ76 family.
