The Pacemaker KBD8020-XXXX is the no-muffler build of this DPF-back system, listed to fit the Mazda BT-50 3L (4JJ3-TCX turbo-diesel, 2020–2025). Running no silencers is the headline: it is the most free-flowing, hardest-sounding layout in the family, with nothing in the run to soak up volume.

What does a no-muffler layout change?

With neither a muffler nor a resonator in the run, this variant leaves the gas path completely open behind the filter. That gives the loudest, most unfiltered note of the BT-50 4JJ3 builds — there is no chambered absorption and no frequency tuning, so the diesel's character comes through hard. It is the layout for owners who want maximum flow and minimum silencing, and it reads very differently from the muffler or resonator versions.

What does DPF-back mean on the 4JJ3 BT-50?

DPF-back means the system replaces everything from the diesel particulate filter rearward, leaving the factory DPF in place. The emissions filter stays on the truck; what changes is the pipework behind it, here run with no added silencer. Pacemaker has not published a pipe diameter for this kit, so we do not state one.

Will it suit my Mazda BT-50?

It is listed to fit the Mazda BT-50 3L 4JJ3-TCX from 2020 to 2025. Treat that as listed-to-fit and confirm your exact build with the workshop before ordering — and bear in mind the no-muffler note is the loudest in the range when you choose it.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this Pacemaker DPF-back system in-house across the Illawarra. We confirm hanger positions and clearance along the run, then book the bay once the build is verified. The KBD8020-XXXX RRP is published.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.

Common questions

How loud is the KBD8020-XXXX compared to the others?
It's the no-muffler layout, so it's the loudest and most free-flowing of this family — nothing in the run absorbs or tunes the note.
Does it keep the DPF?
Yes — it's a DPF-back system, so the diesel particulate filter stays and only the pipework behind it is replaced.
What pipe size is it?
Pacemaker hasn't published a diameter for this kit, so we don't state one. Confirm the spec with the workshop.
