Holden Colorado RG 2.8L (DURAMAX) TD 2012 to September 2016 (without DPF/Air Purifier) - Single 3" Kit.
Category: Complete exhaust systems


The Pacemaker KB5110-XXMX is a single 3in DPF-back kit listed to fit the Holden Colorado RG 2.8L Duramax turbo-diesel (without DPF/air purifier) from 2012. It's supplied by Pacemaker at an RRP of $1629.05.
This is a single 3in exhaust kit for the RG Colorado's 2.8L Duramax, listed for builds without a DPF or air purifier. The DPF system type in the listing reflects this generation's exhaust architecture. It's the sibling to the with-cat version, ordered where the catalytic converter is handled separately. Pacemaker hasn't published the material, muffler configuration or whether a cat is included for this KB5110-XXMX, so we confirm those off the part. The 3in diameter is the confirmed spec.
This kit is listed to fit the Holden Colorado RG 2.8L Duramax from 2012 to September 2016, for builds without a DPF or air purifier, with four concrete fitment matches. That DPF/air-purifier distinction is the key detail, and listing data can be imperfect, so treat it as a starting point. Send us your exact build and we'll confirm the KB5110-XXMX before ordering.
Pacemaker hasn't published the cat configuration or a formal compliance status for this kit, so we won't make road-registration claims we can't support. We'll confirm how the KB5110-XXMX is configured and how it sits against NSW requirements before fitting.
Oak Flats Muffler Men supplies and fits the KB5110-XXMX in our Illawarra workshop. We first confirm your Colorado is the non-DPF/non-air-purifier build this kit is listed for, then match the single 3in kit on the hoist, check clearances, hangers and how the cat is handled, and book the bay.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
