Mazda BT-50 3L (4JJ3-TCX) 2020 to 2025 (DPF Back) Exhaust No Mufflers.
Category: Mufflers and resonators


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.
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.
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.
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.
