Scoped to the August 2010 to June 2012 build window, the Pacemaker KB5101-XCMX is a single 3in with-cat exhaust kit for the Holden Colorado RC Dual Cab 3L (4JJ1-TCX turbo-diesel). It carries a listed RRP of $1,943.10.

How do we confirm the KB5101-XCMX fits your Colorado?

Oak Flats Muffler Men fits this kit in our Illawarra workshop, and the first thing on the hoist is the build date. The RC Colorado ran in separate windows; the KB5101-XCMX is the August 2010 to June 2012 code, and there's a different code for the earlier RC. Five concrete fitment matches sit behind this listing, but listing data can be imperfect, so we check the single 3in kit and its cat against your truck, confirm the hangers and clearances, and only then book the bay.

Is the KB5101-XCMX road legal?

This is a with-cat kit, so the catalytic converter stays in the run rather than being deleted — the emissions hardware the Colorado relies on is kept. Pacemaker hasn't published a formal compliance status against this code, so instead of a blanket registration claim we go over how it sits against NSW requirements for your specific build before fitting.

Why choose the with-cat version?

On the 3L 4JJ1-TCX turbo-diesel, the single 3in run steps the bore up over a smaller factory pipe for a freer flow and a fuller note, louder than stock without being raucous. Keeping the cat is the point of difference from the without-cat version of the same later-RC kit: you get the bigger bore while leaving the factory emissions hardware in place, which is the sensible pick for a registered ute.

What's confirmed off the part rather than the listing?

The record gives the single 3in bore, the with-cat configuration, the 4JJ1-TCX engine and the $1,943.10 RRP. Pacemaker hasn't published the material or muffler arrangement, so we confirm those against the physical kit rather than read them into the title.

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

Common questions

Which RC Colorado build is the KB5101-XCMX for?
The later RC Dual Cab 3L from August 2010 to June 2012. A separate code covers the earlier RC, so we pin down your build date first.
Is the catalytic converter kept?
Yes — it's the with-cat kit, so the cat is retained as part of the run.
What bore is it and what does it cost?
A single 3in kit at a listed RRP of $1,943.10. Pacemaker hasn't published the material or muffler, so we confirm those off the part.
