The Redback K-RPM15770 is a cat-back exhaust listed for the Holden Caprice from 1990, catalogued at $586.77.
This entry names the Holden Caprice from 1990 at a recommended retail of $586.77. As a cat-back it spans the rear of the exhaust from the catalytic converter to the tailpipe — the section that renews the silencing and the part of the run that takes the most corrosion over a long life. No bore, material or muffler detail is published by Redback for this listing, so we keep strictly to what is recorded and confirm the rest off the kit at fitting.
On a Caprice of this era, swapping the cat-back replaces the back pipework and silencing and changes the note relative to a worn factory muffler, with the emissions hardware up front left standard. We describe that as a rear-section renewal with a tonal shift rather than a performance figure, because the record holds no sound or output data to quote.
It is listed to fit the Holden Caprice from 1990, and as a cat-back it leaves the factory catalytic converter and emissions hardware untouched, with no cat-delete flagged on the K-RPM15770. Build variations across the Caprice can still decide whether a kit lines up cleanly, and registration detail varies, so send your exact Caprice and we will confirm both fitment and any state requirement before it is ordered.
Oak Flats Muffler Men supplies and fits this Redback cat-back across the Illawarra. We match the K-RPM15770 to your Caprice, check the rear pipework clears the underbody and hangers, set the tailpipe and book the bay. On a 1990 Holden, availability is worth a quick call first.
