Will the K-RPM14588 fit my Holden Commodore?

It's listed to fit the Holden Commodore from 01/1988. Exhaust fitment data can be imperfect on older cars, so confirm your exact variant with the workshop before ordering.

Does this replace the catalytic converter?

No. As a cat-back it replaces the pipework, mufflers and tailpipe from the catalytic converter rearward and leaves the factory cat and front pipe in place.

Will it be louder than standard?

A cat-back typically changes the note compared with the factory muffler, but the supplier doesn't publish sound data, so we won't quote a figure. It's the rear section that's renewed and resilenced.

The Redback K-RPM14588 cat-back is listed for the Holden Commodore from 01/1988, at $1,729.86 RRP — one of the earliest-dated Commodore systems in the range — supplied through SWD and fitted at Oak Flats Muffler Men in the Illawarra.

What's specific to this early Commodore listing?

The K-RPM14588 is matched to the Holden Commodore from 01/1988, which makes it one of the oldest start dates in this group of listings. On a Commodore that age the rear run takes the most corrosion and knocks over a long life, so it's exactly the section a cat-back renews. The $1,729.86 retail is the only published hard figure — diameter and material aren't given by Redback for this part, so we confirm the spec against your car.

What does a cat-back renew here?

A cat-back runs from the catalytic converter outlet to the tip, so it renews the mufflers and rear pipework while leaving the factory cat and front pipe alone. The honest read on a long-serving Holden: it freshens the rear and can change the tone relative to a worn standard silencer, but it's a replacement-and-refinement job, not a performance promise. New pipe and a changed note is generally the point.

Will it suit my Commodore?

It's listed to fit the Holden Commodore from 01/1988; we treat listed fitment as a starting point, not a guarantee. Tell us your exact Commodore and we'll match it against the K-RPM14588 listing and flag anything that needs checking before the part comes in — feed data on cars this old can be imperfect.

What does fitting involve at our Illawarra workshop?

Fitting happens at Oak Flats Muffler Men in the Illawarra: we mount the K-RPM14588, set the alignment and tailpipe position, and check it seals against the factory front section. On a Commodore this age, availability is worth confirming with us first, as it's typically a special-order line.

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