The MPI Automotive MKTY0028 is a 3in turbo-back exhaust for the HDJ78 4.2L Toyota Landcruiser Troop Carrier, finished with a chambered muffler. The full muffler is the defining choice — more silencing than a compact resonator, for a Troopy owner who values a quiet cabin on long touring runs.

What does the rear muffler change?

A turbo-back replaces the exhaust from the turbo outlet rearward, the full span where the 4.2L turbo-diesel frees up most. Finishing it with a chambered muffler — which reflects and absorbs sound internally — keeps the note subdued for highway and outback driving. That makes this the settled, quieter option in the HDJ78 turbo-back range, trading the most open sound for cabin comfort.

What's the bore and material?

At 3in, this turbo-back gives the 4.2L diesel a generous path from the turbo back. MPI Automotive hasn't published the material for this listing, so if stainless versus aluminised corrosion life matters on a working Troop Carrier, confirm what's supplied with the workshop before ordering.

Will it suit my HDJ78 4.2L Troopy?

It's listed to fit the Toyota Landcruiser HDJ78 4.2L Troop Carrier. The cat status isn't published for this listing, so if road compliance matters for your build, ask the workshop to verify what the system retains. Confirm your exact vehicle and any prior exhaust work too.

Oak Flats Muffler Men supplies and fits Landcruiser turbo-back systems on the hoist across the Illawarra. We run the 3in pipe from the turbo back, mount the rear muffler, set the hangers, and confirm the part suits your Troopy before any cutting. Send your details to book the bay.

Common questions

Is the MKTY0028 quieter than the hotdog version?
It uses a chambered rear muffler, which silences more than a compact hotdog, so the note sits more subdued. It's a 3in turbo-back for the HDJ78 4.2L Landcruiser Troop Carrier.
What bore is it?
It's a 3in turbo-back. The material isn't published by the supplier — ask the workshop if it matters to your build.
Is it road legal?
The cat status isn't published by the supplier, so compliance can't be confirmed from the spec. Ask the workshop to verify what the system retains for your Troopy.
