Category: Mufflers and resonators


The MPI Automotive SSMKTY0383 is the with-cat member of the later LandCruiser VDJ79 turbo-back range — it keeps the catalytic converter while deleting the rear muffler, in stainless steel. A 4in single-side-exit system, listed to fit the Toyota LandCruiser VDJ79 V8 4.5L turbo-diesel dual cab ute (2016–2025).
This is the open-but-cat-retained turbo-back: the rear muffler is gone, so there's no chambered silencer in the tail and the note is louder and harder than a muffled build — but the catalytic converter stays, so the emissions hardware on the later VDJ79 is left in place. It's the choice for an owner who wants the open 4in sound without a cat delete. We describe the character from the configuration, not from any sound figure, which isn't published for this part.
A turbo-back replaces the system from the turbo outlet rearward — the longer span where a diesel V8 frees up — and this one runs the 4in bore MPI lists for it through to a single side exit. It's the stainless build, picked for corrosion life on a working 79 Series that meets mud, salt and water. We state only the 4in diameter and the stainless construction recorded; no grade or flow number is added.
The single side exit routes the tailpipe out ahead of the rear wheel rather than over the back bar — useful on a dual cab carrying tow gear or tray work at the rear. It's a packaging decision for this 79 Series body. We confirm the exit clears your tray and bar setup before fitting.
It keeps the catalytic converter, so the emissions hardware that matters for compliance on the VDJ79 stays in place. Deleting the rear muffler is a noise change rather than an emissions one, but it can affect noise compliance — so confirm the exact build and any NSW requirements with the workshop before fitting. Oak Flats Muffler Men fits these in-house across the Illawarra.
