Holden Colorado RC 3.0L 08 - 10 LWB With Cat & Without Muffler (MKHN0372) Fits HOLDEN. Fast shipping.
Category: Mufflers and resonators


The MPI Automotive MKHN0372 keeps the catalytic converter but deletes the rear muffler on the long-wheelbase Holden Colorado RC 3.0L. The muffler-delete is the defining move: cat in, muffler out, for a louder note on a cat-retained system.
Pulling the rear muffler removes the chambered box that absorbs and reflects sound, so the note opens up and the system flows more freely at the back. Because the MKHN0372 keeps the catalytic converter, only one of the two factory restrictions is gone — it's louder than a muffled build but still carries the cat that the full-delete versions remove.
The MKHN0372 retains the catalytic converter, which is the emissions component that usually decides registration on a diesel ute. Compliance still depends on the full vehicle, noise rules and your state's requirements, so confirm the exact build and any NSW conditions with the workshop before fitting — a muffler-delete can change the noise picture.
This part is routed for the long-wheelbase Colorado RC 3.0L, with pipe lengths and mounting points to suit that longer chassis — a separate listing from the short-wheelbase ute. Exact years aren't published in the supplier record, so confirm your variant with the workshop before ordering.
