Redback Redback Manifold Catalytic Converter.
Category: Extractors and headers


The Redback C2235 is a manifold catalytic converter listed to fit the Holden from 2004. It combines the exhaust manifold and catalytic converter in a single bolt-on assembly — the front-section replacement for a cracked manifold or a spent cat on this small car.
On the 2004 Holden the catalytic converter sits close to the manifold, and the C2235 replaces both as one Redback unit. When the converter substrate breaks down or the manifold cracks, this assembly restores the front section in a single part rather than matching a loose manifold to a separate cat.
It's listed to fit the Holden from 2004. Cat-manifold fitment is engine and emissions-spec specific, so we confirm the C2235 against your exact car before ordering — send the compliance plate and we'll verify the flange and converter match.
Because the C2235 keeps a catalytic converter in the exhaust rather than removing one, it's the emissions-retaining replacement for a road-registered Holden. Final NSW compliance depends on the converter matching the car's original specification, which we confirm before fitting.
Oak Flats Muffler Men fits Redback manifold catalytic converters across the Illawarra. We confirm the C2235 suits your Holden, fit new gaskets, check the sensor bung and downstream pipe, and reseal the joint for heat cycling. RRP is listed at 569 AUD; fitting is quoted once we've seen the car.
