Redback's K-RPM15638 is a cat-back exhaust listed to fit the Holden Calais from 1988, with an RRP of $2315.64. It replaces the exhaust from the catalytic converter back to the tailpipe.

What part of the system is the K-RPM15638?

It is a cat-back, which means it is the rear run of the exhaust: the pipework, mufflers and tailpipe sitting behind the catalytic converter. The cat and the front pipe stay as Holden fitted them. On a Calais of this era that targets the section that corrodes first while leaving the emissions hardware in place. Redback do not publish a diameter or material grade for it.

Will it suit my Holden Calais?

It is listed to fit the Holden Calais from 1988. Fitment listings for cars this old can be imperfect, so we confirm your specific Calais, its body style and any earlier exhaust repairs before ordering the K-RPM15638, so it mates correctly at the converter.

What does a cat-back do to the sound?

Renewing the rear silencing usually gives a cleaner, fuller note than a worn standard muffler. The exact result varies with the car, and Redback publish no measured sound data, so we will not quote a level. Since only the rear section is changed, the difference is a refreshed back-of-car note rather than a wholesale change to how the exhaust sounds.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fit it on the hoist, checking the cat joint, hangers and clearances from the converter to the tailpipe. On a heritage Calais the original hangers and mounting points may have aged, so we make sure the K-RPM15638 is carried cleanly before the car comes down. At $2315.64 and being an older Holden part, it is usually ordered in; we confirm stock before you commit.

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