The Pacemaker KBD8020-XXRX is the resonator build of this DPF-back system, listed to fit the Mazda BT-50 3L (4JJ3-TCX turbo-diesel, 2020–2025). The resonator is the headline: a tuning device that targets drone frequencies, so it takes the boom out of the note without the broader muffling of a chambered unit.

What does the resonator do on this BT-50?

A resonator silences by interference rather than absorption. Tuned to a specific band of frequencies, it cancels the low boom that turns into cabin drone at a steady cruise, while letting the rest of the gas flow with little restriction. On the 4JJ3 diesel that gives a system noticeably calmer than the no-muffler build but more open than a chambered muffler — it trims the drone and keeps the character.

What does DPF-back mean here?

This is a DPF-back system, replacing the pipework from the diesel particulate filter rearward and leaving the factory DPF in place. The emissions filter stays on the truck while the run behind it is reworked around the resonator. Pacemaker has not published a pipe diameter for this kit, so none is stated.

Will it suit my Mazda BT-50?

It is listed to fit the Mazda BT-50 3L 4JJ3-TCX from 2020 to 2025. As with all feed-based fitment, confirm your exact build and year with the workshop before ordering so we know it lines up with your truck.

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 check the resonator hanger position and clearance along the run, then book the bay once your build is confirmed. The KBD8020-XXRX RRP is published.

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

Common questions

What does the resonator change versus the no-muffler version?
The resonator tunes out drone frequencies, so it's calmer than the no-muffler build while staying more open than a chambered muffler.
Is the DPF left in place?
Yes — it's a DPF-back system, so the diesel particulate filter stays and only the pipework behind it is replaced.
What diameter is it?
The supplier hasn't published a pipe size for this kit, so we don't state one. Confirm with the workshop.
