Landcruiser GDJ76 Wagon, 2.8L TD, 2023-Current, 3in Turbo Back With Cat & With Muffler.
Category: Mufflers and resonators


This is the keep-it-all GDJ76 build: the MPI Automotive SSMKTY0417 is a 3in turbo-back that retains the catalytic converter and a rear muffler, listed to fit the Toyota Landcruiser GDJ76 wagon 2.8L turbo-diesel (2023-current). Cat retained, silencer retained — the most restrained variant of the family.
The SSMKTY0417 keeps the factory catalytic converter and runs a rear muffler, so it steps up the pipe sizing from the turbo back without removing the emissions hardware or the silencing. On the GDJ76's 2.8L diesel that means a fuller note than stock while staying the most civilised option of the set — the chambered muffler absorbs and reflects sound at the back, and the cat stays in the path. It suits an owner who wants the bigger-bore system with the quietest result.
Because the SSMKTY0417 keeps the catalytic converter, it retains the emissions equipment the Landcruiser left the factory with — the part that matters most for road compliance on a diesel. State noise and registration rules still apply to any modified system, so 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 span. The supplier lists this at a 3in bore, sized to a worked 2.8L diesel. Both the cat and the muffler sit in that 3in run, so the gas passes through the converter and the silencer on its way out — the fullest-equipped configuration of the GDJ76 family.
