The MPI Automotive SSMKTY0377 is a 4in stainless turbo-back system for the V6 Toyota Landcruiser 300 Series, run with the catalytic converter retained but without a muffler — the keep-the-cat, free-flowing build.
What does 'with cat, without muffler' mean here?
This SSMKTY0377 keeps the catalytic converter but runs no muffler — so it retains the factory emissions hardware while flowing freely through a 4in run with nothing chambered to absorb sound. It's louder than the with-muffler build by design, suiting an owner who wants the cat kept but the freer-flowing, harder note of a muffler-less system on the 300 Series V6.
Is it road legal?
Keeping the catalytic converter retains the emissions equipment that matters for road compliance on a diesel V6. But running without a muffler changes the vehicle's noise output from standard, which has its own state requirements, and we can't certify any specific build from the listing. Confirm the configuration, noise rules and intended use with the workshop before fitting.
What is a 4in turbo-back system?
Turbo-back replaces the exhaust from the turbo outlet rearward — a longer span than a cat-back, taking in the section where a twin-turbo diesel V6 frees up. At 4in it's the large-bore choice sized for the engine, with the cat retained. The stainless build resists corrosion on a hard-working 300 Series.
Will it suit my 300 Series, and how do we fit it?
It's listed to fit the V6 Toyota Landcruiser 300 Series at 4in. Oak Flats Muffler Men supplies and fits this MPI Automotive system in-house across the Illawarra, confirming the turbo interface, the cat position and clearances. Confirm the exact build with the workshop, as feed data is a guide only.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Does the SSMKTY0377 keep the cat?
- Yes. It's the with-cat turbo-back, retaining the factory catalytic converter, but it runs without a muffler so it flows more freely and is louder.
- Is it road legal?
- Keeping the cat retains the emissions equipment, but running no muffler changes noise output and we can't certify a build from the listing. Confirm the configuration and noise rules with the workshop.
- What does turbo-back cover?
- It replaces the exhaust from the turbo outlet rearward — a longer span than a cat-back — at 4in on the 300 Series V6, with the cat retained.
