The MPI Automotive MKHN0443 keeps the factory cat but runs without a muffler, routed for the long-wheelbase 3.0L Holden Colorado RC (2010–2012). That pairing — emissions hardware retained, muffler deleted — gives a harder note on the LWB ute while staying registration-minded.

What does keeping the cat but dropping the muffler give you?

The MKHN0443 holds onto the factory catalytic converter, which is what matters for road compliance on a diesel ute, but deletes the muffler. With no absorptive element in the run, the path is freer and the note more present than a muffled system, yet the cat stays where the factory had it. It's the build for a Colorado RC owner who wants a harder character without changing the emissions side. Confirm any state requirements with the workshop before fitting.

Why is the LWB routing the starting point?

The Colorado RC came short and long wheelbase, and the system has to follow the chassis it's cut for. The MKHN0443 is bent and hung for the longer LWB tub, so matching the wheelbase is the first check — a SWB system won't sit right on a LWB ute. The MKHN0443 carries a published RRP of $1,895.14.

Will it suit my Colorado RC?

It's listed to fit the 3.0L Holden Colorado RC, LWB, across the 2010–2012 window. Confirm your exact build and wheelbase with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits MPI Colorado RC systems in-house across the Illawarra. We confirm the LWB routing, check clearances, and match the part to your ute before it goes on the hoist.

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

Common questions

Does the MKHN0443 keep the catalytic converter?
Yes — this is the with-cat build, so the factory catalytic converter stays in place. Confirm any state requirements with the workshop before fitting.
Is this the LWB or SWB system?
It's the LWB (long-wheelbase) routing. Make sure your Colorado RC's wheelbase matches before ordering — we'll confirm it.
How does deleting the muffler change the note?
With no muffler in the run there's no absorptive damping, so flow is freer and the note more present than a muffled version. We don't publish decibel figures.
