The MPI Automotive MBM242MF is a 3in dual Y-pipe muffler listed to fit the Toyota Landcruiser VDJ79 4.5L V8. The Y-pipe layout is its defining feature — it merges the twin feed into the muffler in one assembly.

What does the dual Y-pipe layout do?

The standout feature of the MBM242MF is its dual Y-pipe design: the twin pipes merge through a Y into the muffler as a single 3in assembly. That keeps the routing tidy on the VDJ79 while feeding both sides into one silencer. As a muffler it quietens by absorption and reflection inside the body, taming drone on the turbo-diesel V8 while the 3in bore keeps the section sized for the engine's flow. It is a single mid/rear assembly rather than a complete system.

Why 3in on a 79-series V8?

The MBM242MF is built on a 3in pipe — the larger of the common 4x4 exhaust sizes, suited to the 4.5L turbo-diesel V8's exhaust volume. We state only the supplier's 3in figure; material and other specs are not published, so we confirm them against your truck. The dual feed into the Y keeps both manifold banks flowing into the one muffler.

Will it suit my VDJ79 V8?

It is listed to fit the Landcruiser VDJ79 4.5L V8. The 79-series chassis sets the hanger and routing positions this Y-pipe assembly is built around. Confirm your exact build and any other exhaust mods with the workshop before ordering, since the listing describes the fit rather than guaranteeing it on every variant.

What does fitting involve in the Illawarra?

Oak Flats Muffler Men fits 79-series Y-pipe mufflers in-house across the Illawarra. We mount the 3in assembly to your truck's hangers, check the Y-merge clearance to the chassis and driveline, and confirm it lines up before booking you in.
