The K-RPM15681 from Redback is a cat-back exhaust listed to fit the Holden Calais from 1988. Its $2513.75 AUD recommended retail is the highest in this group of period Holden systems, so it reads as a full long-run kit rather than a short tailpipe swap.
What does the K-RPM15681 replace?
As a cat-back, it takes over from the back of the catalytic converter and runs the rest of the way to the tailpipe — the mid and rear pipe, plus the mufflers. The converter and everything forward of it stay factory. Redback hasn't published a diameter or a material grade for this part, so we don't quote either figure; the kit is measured against the car when it lands.
Is this listed for my Calais?
Redback lists the K-RPM15681 against the 1988 Holden Calais. Only two concrete fitments sit behind that, and the data on cars this old can be patchy, so we treat it as 'listed to fit' and check it physically. Give us your exact build and we'll verify the match before we order anything in.
Where does a cat-back leave registration?
The catalytic converter and the emissions gear ahead of it are untouched by a cat-back, which is the section that counts for road compliance. The supplier makes no compliance claim for this kit and neither will we — talk your NSW requirements through with the workshop first.
How does fitting work at our Oak Flats bay?
We special-order the K-RPM15681 and fit it in-house across the Illawarra. A late-'80s Calais will usually need its perished hangers and mounts looked at while the system is off, so we check those and offer the new kit up carefully rather than trusting that a listed part bolts straight in.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Does the K-RPM15681 fit a 1988 Holden Calais?
- It's listed to fit the 1988 Calais. As a listed fitment on an old car, confirm your exact build with us before ordering.
- Is the catalytic converter replaced?
- No. A cat-back only renews the pipe and mufflers behind the converter; the factory cat stays put.
- Why does it cost more than other Redback kits here?
- Redback lists it at $2513.75 AUD, the dearest in this batch. We confirm the current figure and availability when you book it in.
