The MPI Automotive MKHN0377 swaps the rear muffler for a compact hotdog resonator on the Holden Colorado RC 3.0L short-wheelbase, while deleting the catalytic converter. The hotdog is the difference here: a straight-through tuning section rather than a chambered box.
What is a hotdog and what does it do?
A hotdog is a small, straight-through resonator — gas passes through a perforated core rather than bouncing through baffles. It takes the hard edge off the note and trims resonance without choking flow the way a full chambered muffler does. On this Colorado RC build it sits in place of the rear muffler, so the tone is freer than a muffled system but more settled than a pipe with nothing in it at all.
Is this build road legal?
No. The MKHN0377 deletes the catalytic converter, so it is not ADR 79/04 compliant for road registration in NSW and is for off-road use only. The hotdog changes the sound character, not the compliance position — removing the cat is what sets the legal status, and there's no way to soften that.
Will it suit my Colorado RC?
It's listed to fit the Holden Colorado RC 3.0L in short-wheelbase form. The supplier doesn't publish exact years or engine codes in this record, so confirm the precise variant with the workshop. The short-wheelbase routing is specific to this part, separate from the long-wheelbase listing.
What's involved in fitting it locally?
Oak Flats Muffler Men fits the MKHN0377 at our Illawarra workshop, lining up the hotdog section and checking clearance under the tray as it goes in. It's listed to fit the SWB Colorado RC 3.0L; send us your build and we'll confirm and book it. We'll also flag the off-road-only status up front.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- How is a hotdog different from a normal muffler?
- A hotdog is a straight-through resonator that trims tone with less restriction. A chambered muffler quietens more by reflecting and absorbing sound through baffles. This SKU runs the hotdog instead of a rear muffler.
- Is the MKHN0377 legal to register in NSW?
- No. With the catalytic converter removed it isn't ADR 79/04 compliant for NSW road registration and is for off-road use only.
- Does the hotdog make it quiet?
- It settles the note compared with an empty pipe, but it flows more freely than a full muffler, so it's not a quiet build.
