Landcruiser GDJ76 Wagon, 2.8L TD, 2023-Current, 3in Turbo Back With Cat & Without Muffler (MKTY0415).
Category: Mufflers and resonators


Cat kept, muffler dropped: the MPI Automotive MKTY0415 is a 3in turbo-back that retains the catalytic converter and runs no rear muffler, listed to fit the Toyota Landcruiser GDJ76 wagon 2.8L turbo-diesel (2023-current). It opens up the back of the system while leaving the emissions hardware in place.
The MKTY0415 keeps the factory catalytic converter — the part that counts most for compliance on a diesel — and leaves out the rear muffler. Without a chambered silencer at the back, it flows more freely and runs louder than the muffled or hotdog builds, but the converter stays in the run. It is for an owner who wants the open note while keeping the cat in place rather than deleting it.
Because the MKTY0415 keeps the catalytic converter, it leaves the key emissions hardware the Landcruiser left the factory with in the system. A no-muffler exhaust is louder, so state noise and registration rules still apply to the modified setup; confirm the exact build and any requirements with the workshop before fitting.
A turbo-back replaces the exhaust from the turbo outlet rearward, the full engine-back run. The supplier lists this MKTY0415 at a 3in bore, sized to a worked 2.8L diesel. With the cat retained and no muffler at the rear, the 3in pipe carries the gas through with the converter as the only major device in the path — the open-but-cat-retained middle ground of its line.
