Redback list the K-RPM15640 to fit the Holden Commodore from 1990, at an RRP of $2507.04. It is a cat-back exhaust, covering the system from the catalytic converter back to the tailpipe.
Does a cat-back change how the Commodore sounds?
Fitting fresh rear silencing in place of a worn factory muffler usually gives a fuller note, though the exact result depends on the car. Redback publish no sound measurements for the K-RPM15640, so we describe the change honestly rather than quoting a decibel level. Because only the section behind the converter is renewed, the difference is a refreshed rear note rather than a reworking of the whole exhaust.
Will it suit my Holden Commodore?
It is listed to fit the Holden Commodore from 1990. Fitment listings for cars this age can be imperfect, so we confirm the Commodore's model, body and any earlier exhaust repairs before ordering the K-RPM15640 in, checking it lines up at the converter.
What does a cat-back replace?
A cat-back is the rear run of the exhaust: the intermediate pipe, mufflers and tailpipe behind the catalytic converter. The cat and front pipe are left standard, so the K-RPM15640 renews the corroded rear half without touching the emissions hardware. Redback list no diameter or material grade for it.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fit it on the hoist, checking the converter joint, hangers and tailpipe clearance before signing off. At $2507.04 it is generally ordered in for these older Commodores, so we confirm stock first.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
