Pacemaker Australia Holden Colorado RG 2.8L (DURAMAX) September 2016 to December 2020 (DPF Back) Exhaust System no Muffler.
Category: Mufflers and resonators


The Pacemaker KBD5110-XXXX is a no-muffler DPF-back system, listed to fit the Holden Colorado RG 2.8L Duramax (September 2016 to December 2020). The no-muffler layout is the headline: with nothing in the run to absorb or tune the note, it is the most open and unfiltered of the Colorado DPF-back builds.
With no muffler or resonator in the run, this system leaves the gas path open behind the filter. There is no chambered absorption and no frequency tuning, so the 2.8L Duramax diesel comes through hard and present. It suits owners who want the flow benefit of a DPF-back run and the loudest, most unfiltered note, accepting the trade-off of more cabin sound at cruise.
DPF-back means the system replaces everything from the diesel particulate filter rearward, leaving the factory DPF untouched. The emissions filter stays on the truck while the pipework behind it is opened up — here with no silencer fitted. Pacemaker has not published a pipe diameter for this kit, so we do not state one.
It is listed to fit the Holden Colorado RG 2.8L Duramax from September 2016 to December 2020. Treat that as listed-to-fit and confirm your exact build and year with the workshop before ordering, since the build window is specific.
Oak Flats Muffler Men supplies and fits this Pacemaker DPF-back system in-house across the Illawarra. We confirm the hanger positions and clearance along the run, then book the bay once the build is verified. The KBD5110-XXXX RRP is published.
