Landcruiser GDJ79 Ute, 2.8L TD, 2023-Current, 3in Turbo Back Without Cat & With Muffler (SSMKTY0407).
Category: Mufflers and resonators


Running a rear muffler, the MPI Automotive SSMKTY0407 is a 3in turbo-back exhaust listed to fit the Toyota Landcruiser GDJ79 2.8L turbo-diesel ute from 2023. The muffler is the point of difference: it chambers the four-cylinder diesel's note for the most subdued tone in this turbo-back group.
The SSMKTY0407 fits a rear muffler that absorbs and chambers sound, so it's the quietest-mannered of the GDJ79 turbo-back options — the choice for owners who want the freer-flowing 3in run without a hard note. Stainless construction gives the corrosion life a working Landcruiser needs.
Turbo-back means the system is replaced from the turbo outlet rearward — a longer span than a rear-section swap. Sized at 3in for the GDJ79's 2.8L turbo-diesel, it's about keeping the run clear from the turbo back on a ute that tows and works on dirt. The stainless build is for corrosion life over the long haul.
This build runs without the catalytic converter, so removing the catalytic converter means it is not ADR 79/04 compliant for road registration in NSW, so it's for off-road use only. Talk to the workshop about your registration and intended use before committing.
