Running no muffler at all, the MPI Automotive MKTY0333 is a 3in turbo-back listed to fit the Toyota LandCruiser 4.2L Troopy (HDJ78 and HZJ75). The no-muffler layout is its defining trait — it is the most open, free-flowing version, with nothing in the run to absorb the note.

What does a no-muffler turbo-back mean?

Without a muffler box in the path, the MKTY0333 leaves the 3in pipe to flow straight from the turbo to the tail. That is the most open configuration MPI offers for this Troopy: minimal back-pressure and the hardest, most present note of the family, because there is no chambered or absorptive element softening it. It suits owners who want maximum flow and don't mind the louder character that comes with deleting the muffler.

What is a turbo-back on the Troopy?

A turbo-back replaces the exhaust from the turbo outlet rearward — here at 3in — across the full length of the system. On the HDJ78/HZJ75 4.2L that is a meaningful step up in bore over the factory run, and choosing the no-muffler version means the only acoustic treatment is whatever you add later if you change your mind.

Is it road legal?

Whether the catalytic-converter and emissions hardware are affected isn't published for this part, so road compliance comes down to your specific vehicle and any noise rules that apply to a muffler-delete. Confirm the legal position for your Troopy with the workshop before fitting — a no-muffler system in particular can run into noise limits.

Will it suit my HDJ78 or HZJ75 Troopy?

It is listed to fit the Toyota LandCruiser 4.2L Troopy in HDJ78 and HZJ75 form; confirm the exact build with the workshop, as detail varies across these models. Oak Flats Muffler Men supplies and fits 3in turbo-back systems like this in-house across the Illawarra and can talk through whether you want a muffler added down the track.

Common questions

Does the MKTY0333 come with a muffler?
No — it's the without-muffler version, the most open and loudest layout in the range. A muffler can be added later if you want to quieten it.
Which Troopy does it fit?
It's listed to fit the 4.2L LandCruiser Troopy in HDJ78 and HZJ75 form. Confirm your exact model with us first.
How loud will it be?
With no muffler it will be on the louder, harder end, but we can't give a decibel figure — there's no measured sound data.
