The Redback K-RPM15633 is a 2.5in cat-back exhaust listed to fit the Holden Commodore VS wagon. It replaces the exhaust from behind the catalytic converter back to the tailpipe, leaving the factory front pipework in place.
What does this system cover?
This K-RPM15633 is a 2.5in cat-back for the Commodore VS wagon, covering the pipework, mufflers and tailpipe from the catalytic converter rearward. The factory cat and front pipe stay in place. Redback publish the 2.5in pipe size for this listing; material grade is not stated, so we confirm it on the bench. On an older wagon this is usually the section that needs renewing first.
What is a cat-back and what does it change?
A cat-back is the section a workshop reaches for when the back of an exhaust has had enough. It runs from the catalytic converter to the tip, so it renews the mufflers and pipework while leaving emissions gear in place. The honest trade-off: it freshens the rear and can change the tone relative to a stock silencer, but it is a replacement-and-refinement job, not a performance promise. For a long-serving Holden, new pipe and a changed note is generally the point.
Will it suit my Holden Commodore?
It is listed to fit the Holden Commodore VS wagon; exhaust fitment data can be imperfect, so confirm your exact VS build with us before ordering. The wagon body runs different rear pipework to the sedan, which is why the variant matters here, and we will match it against the K-RPM15633 listing before the part comes in.
What does fitting involve at our Illawarra workshop?
Fitting happens at our Oak Flats Muffler Men workshop in the Illawarra: we mount the K-RPM15633, set the alignment and tailpipe position, and check it seals against the factory front section. It is listed at $570.05. For an older Holden model like this, availability is worth confirming with us first.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
