HFD-VDJ79 V8 4.5L TD, (DPF) Ute 2016 To Current, 4in Single With Cat & Muffler (SSMKTY0394) Fits TOYOTA.
Category: Mufflers and resonators


The most complete of the VDJ79 4in range, the MPI Automotive SSMKTY0394 keeps both the catalytic converter and a rear muffler — a 4in DPF-section system listed to fit the Toyota VDJ79 V8 4.5L turbo-diesel ute from 2016. Cat and muffler retained makes this the most road-minded build in the group.
The SSMKTY0394 keeps the factory catalytic converter and adds a rear muffler, so it's the version that leans hardest toward a civil, street-friendly setup. The cat stays in place and the muffler chambers the V8 diesel's note, which separates it clearly from the cat-delete and muffler-delete builds in the same range.
Sized at 4in for the 4.5L V8 diesel, this rear-section build runs a single large bore with the catalytic converter retained and a muffler fitted. Stainless construction gives it the corrosion life a working ute needs on dirt and salt, while the muffler manages volume.
By keeping the catalytic converter, the SSMKTY0394 retains the emissions equipment the ute left the factory with — the usual sticking point on diesel utes — and the muffler keeps the note in check. That doesn't make it automatically legal: confirm the exact build and any state requirements with the workshop before fitting.
