The Redback K-RPD14635 is a cat-back exhaust listed to fit the Holden Commodore from 1991, with a recommended retail of $2,732.34. It is supplied through our distributor and fitted at our Illawarra workshop.

What's covered by a cat-back, and what isn't published?

A cat-back swaps the run from behind the catalytic converter through to the tailpipe — mid-pipe, muffler and rear pipework — while keeping the factory cat in place. Diameter, material and muffler configuration aren't published by the supplier for this listing, so we don't quote them. What's on record is that it's a complete cat-back system for the Commodore at a $2,732.34 retail.

What does fitting an older Commodore system involve here?

On a Commodore dating from 1991, the underbody matters as much as the new part. Hangers and brackets perish over decades, and the flange the new section mates to can be tired, so we offer the K-RPD14635 up to your car, set the alignment, and make sure it seals against the factory front section before the booking is complete. That groundwork is the difference between a clean fit and a rattle later.

Will it suit my Commodore?

This listing is matched to the Holden Commodore from 1991. It is listed to fit, not guaranteed; feed data can be imperfect on a car this age, so send your year, body and engine and we'll confirm it against the K-RPD14635 before ordering. The era and the body style both affect how the rear pipework routes underneath.

Does it keep the catalytic converter?

Yes. Because the cat is retained, the factory emissions hardware stays as the Commodore left the factory — only the rear section changes. Confirm any state requirements with our Illawarra workshop before fitting, as we don't make compliance claims the supplier hasn't published. Oak Flats Muffler Men fits the system in-house once it's matched to your car.
