The MPI Automotive MKHN0345 is a DPF-back for the Holden Trailblazer 2.8L, run without a rear muffler. As a DPF-back it starts downstream of the diesel particulate filter — a shorter, rear-of-system run than a turbo-back, and the most affordable build here.
What's a DPF-back and where does it start?
A DPF-back replaces the exhaust from behind the diesel particulate filter rearward, leaving the DPF and everything ahead of it untouched. It's a shorter span than a turbo-back, which is reflected in its lower RRP. On the MKHN0345 there's no rear muffler in the run, so the back of the system flows freely and the note opens up.
What does deleting the muffler change?
With no rear muffler, there's no chambered box to absorb and reflect sound, so the tone is louder and freer than a muffled DPF-back. The system still starts behind the DPF, so it's a rear-of-system change focused on flow and note rather than a full engine-back rebuild.
Is it road legal?
The supplier record doesn't state whether the catalytic converter is included on this DPF-back, so cat status isn't published here. A DPF-back leaves the diesel particulate filter in place, but the muffler-delete changes the noise picture and compliance depends on the full vehicle, noise limits and your state's rules. Confirm the exact build and any NSW requirements with the workshop before fitting.
Fitment and fitting locally
It's listed to fit the Holden Trailblazer 2.8L; the supplier names the engine but not the exact years, so confirm your variant with us. Oak Flats Muffler Men fits the MKHN0345 in-house across the Illawarra, picking up behind the DPF and checking clearance through the rear section as it goes up.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- What's the difference between a DPF-back and a turbo-back?
- A DPF-back starts behind the diesel particulate filter, a shorter rear-of-system run. A turbo-back replaces everything from the turbo outlet back, a longer span.
- Does the MKHN0345 include a catalytic converter?
- The supplier doesn't publish cat status for this DPF-back, so confirm it with the workshop. The DPF itself stays in place.
- Will it be loud?
- With no rear muffler the note opens up, so it's louder than a muffled DPF-back.
