Will the K-RPM15634 fit my Holden Commodore?

It is listed to fit the Holden Commodore from 1988. Confirm your exact variant with the workshop first, as fitment data can be imperfect.

Is this a full exhaust or just the back?

It is a cat-back, so it renews the pipework, mufflers and tailpipe from the converter rearward and leaves the cat and front pipe in place.

The K-RPM15634 is listed at $549.85 and may be ordered in for these heritage Commodores; we confirm stock before you commit.

Redback list the K-RPM15634 to fit the Holden Commodore from 1988, at an RRP of $549.85. It is a cat-back system: the rear of the exhaust, from the catalytic converter to the tailpipe.

Will it suit my Holden Commodore?

It is listed to fit the Holden Commodore from 1988. Fitment listings for cars this old are not always exact, so before we order the K-RPM15634 in we confirm the Commodore's model, body and any previous exhaust work, and check the part lines up at the converter flange. Decades of repairs and replacement sections mean two cars listed the same way can present differently under the hoist, which is why that check matters.

What is a cat-back replacing here?

A cat-back takes over from the catalytic converter rearward: intermediate pipe, mufflers and tailpipe, stopping short of the cat and front pipe. That makes the K-RPM15634 a rear-section renewal rather than a full exhaust rebuild, which is usually exactly what an ageing Commodore needs. The trade-off is that it changes nothing ahead of the converter, so any issue with the cat or front pipe is a separate job. Redback publish neither a pipe diameter nor a material grade for it.

Is it a loud system?

Replacing the rear silencing generally gives a fuller note than a tired factory muffler, but the result depends on the car. Redback provide no measured sound data, so we will not quote a decibel figure.

What does fitting involve at our Illawarra workshop?

At Oak Flats Muffler Men the Commodore goes on the hoist, the old rear section comes off and the K-RPM15634 is offered up with hanger and clearance checks back from the cat. At $549.85 it may be a special-order item, so we confirm stock first.
