Category: Mufflers and resonators


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.
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.
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.
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.
