The K-RPM15705 is a Redback 2.5in cat-back exhaust listed to fit the VS-series Holden Commodore and Calais. Two concrete fitments are recorded, with a $372.67 AUD recommended retail.
Which VS Holdens does it cover?
The listing names the VS Commodore and its Calais sibling, the upmarket badge on the same platform — so one 2.5in kit spans both. Two concrete fitments back it. Both the VS series and the 2.5in bore come from the record, which makes them figures we can quote with confidence. The VS sat right before the VT changeover, and exhaust details shifted across the range, so confirm your exact VS build with us before ordering.
What does a 2.5in cat-back change?
A cat-back renews the run behind the catalytic converter — centre pipe, rear pipe and mufflers — and leaves the converter and front plumbing standard. Here that run is 2.5in, the single bore figure the listing publishes. No material grade or sound data is given, so we don't quote either; a 2.5in system is a sensible step over many factory VS exhausts without being extreme.
Where does it stand for registration?
Because the converter and the emissions hardware ahead of it are untouched, the compliance-critical section stays factory. Redback offers no compliance statement against this listing, and we won't invent one — bring your NSW requirements to the workshop and we'll talk them through first.
How does fitting work in the Illawarra?
We order the K-RPM15705 in and fit it ourselves at Oak Flats. On a VS Commodore or Calais the hangers and rubber mounts have usually aged, so we check those on the day and offer the 2.5in cat-back up rather than assuming a listed kit bolts straight on.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
