Listed to fit the Holden Astra from 2000, the Redback C4113 is a combined manifold and catalytic converter — the first length of pipe off the engine, with the converter built into the same casting rather than bolted on downstream.

Why is the manifold and cat one part on this Astra?

Many small petrol cars of the Astra's era run a close-coupled converter, where the catalytic converter sits right behind the manifold to light off quickly from cold. Redback supplies that whole front section as one unit for the C4113, so a failed converter or a cracked manifold flange is fixed by renewing the assembly. The supplier lists no bore or material for it, and we don't put numbers to those.

Does it suit my Holden Astra?

It's listed to fit the Holden Astra from 2000. The Astra ran several engines across that period, and the supplier doesn't publish the series or engine for this listing, so we treat it as listed-to-fit and confirm it against your build before ordering. Bring the VIN and we'll line it up against the catalogue.

Is it road legal?

Because the C4113 is the catalytic-converter section, fitting it restores the Astra's emissions hardware rather than deleting it. Registrability still hangs on the condition of the full system, which we inspect on the hoist. We make no compliance claim the supplier hasn't stated.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men handles Astra manifold-cat work in-house in the Illawarra. We verify the listing against your VIN, separate the old unit from head and downpipe, fit new gaskets, and reset any oxygen sensors the job disturbs. RRP is listed at 829 AUD; fitting is quoted on inspection.

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

Common questions

Is this just a manifold or does it include the converter?
Both. The C4113 is a manifold with the catalytic converter integrated into the one assembly for the Holden Astra.
Which Astra engine does it suit?
The supplier doesn't publish the engine for this listing, so we confirm it against your VIN and engine code before the part is ordered.
