Will the K-RPT14604 fit my Commodore?

It is listed to fit the Holden Commodore from 09/1991. Confirm your exact variant with the workshop before ordering.

Does it replace the catalytic converter?

No. It is a cat-back, so it renews the pipework behind the converter and leaves the factory cat in place.

Can you fit it in the Illawarra?

Yes. Oak Flats Muffler Men supplies and fits cat-back systems in-house and confirms the fit against your car first. The recorded RRP is $2,517.98.

Redback list the K-RPT14604 as a cat-back exhaust for the Holden Commodore from 09/1991. It is supplied through SWD at a recommended retail of $2,517.98 and replaces the system rearward of the catalytic converter.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this Redback cat-back in-house across the Illawarra. Before anything is booked, your Commodore goes on the hoist so we can check the joint to the existing cat, the hanger points and the clearances down the body. As a Commodore from the early 1990s, the K-RPT14604 is commonly a special-order item, so we confirm stock first.

What does the cat-back cover on this car?

On the Commodore the cat-back is everything behind the catalytic converter: the intermediate pipe, the mufflers and the tailpipe. The K-RPT14604 renews that rear section and leaves the converter and front pipe as Holden built them. It is the middle-ground job — more than a tailpipe swap, less than a full engine-back rebuild — and on a car of this vintage it is usually the section carrying the rust and the restriction.

How does the 09/1991 build window affect fit?

This listing is tied to the Holden Commodore from 09/1991, and that window is the detail we match against, since the line ran more than one driveline through the period. The recorded recommended retail is $2,517.98. Diameter, material and muffler configuration are not published by Redback in our data for the K-RPT14604, so those are confirmed on the bench rather than quoted.

Will it suit my Holden Commodore?

It is listed to fit the Holden Commodore from 09/1991. Exhaust feed data on older cars is not always exact, so send your build and we will confirm the variant before ordering the part in.
