Redback Redback Manifold Catalytic Converter.
Category: Extractors and headers

Listed to fit the Holden Barina from 2005, the Redback C2342 is a manifold catalytic converter — exhaust manifold and catalytic converter built into one bolt-on unit. Redback supplies it as a direct replacement for the factory close-coupled part, listed at 464 AUD.
On a small car like the Barina the manifold and the cat are cast together into one close-coupled unit that bolts to the head — the manifold gathers exhaust from the ports and the converter treats it, with the cat near the engine so it warms up fast. The C2342 replaces that whole assembly. It's the repair when the converter substrate breaks down, the housing cracks, or rattling internals trip a fault, since a cast-in cat isn't patched piecemeal.
The C2342 is a replacement catalytic converter, not a delete — it restores the emissions hardware the Barina was built with rather than removing it, which is the registration-friendly direction for a road car. We confirm the unit suits your specific vehicle and that the finished exhaust meets NSW requirements; as a manifold cat it's a compliant repair, not an off-road part.
It's listed to fit the Holden Barina from 2005. No engine or series is published beyond that year, so we treat fitment as listed-to-fit and confirm the unit matches your car's head, flange and oxygen-sensor arrangement before ordering. The manifold cat has to mate exactly to the engine it's replacing for the fit and seal to hold.
Oak Flats Muffler Men fits Barina manifold cats across the Illawarra. We match the C2342 listing to your car, confirm the flange and sensor ports, then fit it with fresh gaskets so the joint seals clean for the heat. RRP is listed at 464 AUD; the fitting cost is quoted once the car is with us.
