The Redback K-RPM15730 is a cat-back exhaust listed for the Holden Commodore from 1988, carrying a $500.48 AUD RRP. It replaces the exhaust run behind the catalytic converter and leaves the factory front pipework in place.

Which Commodore era does the K-RPM15730 cover?

This listing points to the Holden Commodore from 1988 — the late-1980s wave of Holden's mainstream sedan and wagon. Make is Holden, model is the Commodore; no engine or series is published against the SKU, so we will not assume one. There is no bore size or material on the listing either, and we read both off the part when it lands rather than print a figure the supplier has not.

What is a cat-back, in plain terms?

A cat-back is the back end of the exhaust — the section from the catalytic converter rearward. Replacing it leaves the cat and the front pipe factory, so the emissions hardware is left as Holden assembled it. It is the contained, lower-disruption end of an exhaust upgrade, and the part most owners can practically change. Any change in tone is down to that rear run; we put no number on sound the supplier has not measured.

Will it suit your Commodore?

It is listed to fit the 1988-era Commodore, drawn from supplier fitment data rather than checked against your individual car. Builds varied, so treat the listing as a guide. Send Oak Flats Muffler Men your build year and driveline and we will verify the K-RPM15730 before ordering.

What does fitting involve here?

We supply and fit the K-RPM15730 in-house across the Illawarra. On the hoist we confirm it clears the underbody of your Commodore and seat the hangers, then book the job. The same workshop that orders the kit hangs it.

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