Redback Manifold Catalytic Converter.
Category: Extractors and headers


The Redback CGM0001 is a manifold catalytic converter listed to fit the Holden Vectra from 2000 — the integrated manifold-and-converter front section, supplied as a single replacement unit.
Rather than a bare manifold, the CGM0001 combines the exhaust manifold and the catalytic converter into one assembly that bolts to the engine. On the Vectra of this era the close-coupled converter sits right behind the manifold, so when either wears the practical fix is to renew the whole section. Redback lists no bore or material for it, and we don't put figures to those.
It's listed to fit the Holden Vectra from 2000. The Vectra ran more than one engine across its life and the supplier doesn't publish the engine on this listing, so we treat fitment as listed-to-fit and confirm it against your VIN before ordering.
This is the catalytic-converter assembly, so fitting it keeps the Vectra's emissions hardware in place — not a delete. Whether it passes inspection depends on the condition of the full exhaust, which we check on the hoist. We make no compliance claim the supplier hasn't stated.
Oak Flats Muffler Men fits Vectra manifold-cats in-house in the Illawarra. This is a higher-value unit, so we confirm the listing against your VIN before it's ordered, then free the old assembly, fit fresh gaskets, and check the downstream join. RRP is listed at 1129 AUD; fitting is quoted on inspection.
