The MPI Automotive SSMKTY0409 pairs two choices that don't usually sit together: it keeps the catalytic converter but runs no muffler. The result is a 3in dual turbo-back for the Toyota LandCruiser GDJ79 Ute 2.8L (2023 on) that holds its emissions hardware while flowing straight through.
Cat retained, muffler deleted — what does that give you?
Keeping the cat means the SSMKTY0409 leaves the GDJ79's factory emissions component in place, which is the part that matters for diesel-ute compliance. Deleting the muffler means the back half flows straight through with nothing absorbing sound, so the note is open and hard while the cat stays put. It's a deliberate middle path — more vocal than a hotdog build, but without removing the catalytic converter. Confirm current requirements with the workshop.
How does it sound without a muffler?
With no muffler or resonator behind the cat, 3in dual pipe carries gas to the tips uninterrupted, so this is the louder end of the with-cat options — firmer and more vocal than a hotdog or chambered build, while keeping the emissions hardware the ute came with. It's the pick for an owner who wants the open note but isn't prepared to delete the cat.
Does it suit my GDJ79 2.8L?
It's listed to fit the LandCruiser GDJ79 Ute 2.8L turbo-diesel from 2023; confirm your variant with us before ordering, as feed data can lag. RRP is $4,298.31, brought in to order as a turbo-back system rather than carried on the shelf.
Fitting at our Illawarra workshop
Oak Flats Muffler Men fits these in-house. With no muffler to damp resonance, we focus on hanger isolation and clearance so the body stays quiet, then verify the cat seal and dual-exit routing.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Does the SSMKTY0409 keep the cat?
- Yes — it retains the catalytic converter while running no muffler. Confirm current registration requirements with the workshop.
- Is there any muffler or resonator?
- No. It's a straight-through layout behind the cat, so it's louder and freer-flowing than the hotdog or chambered versions.
