The Redback C0021 is a manifold catalytic converter listed to fit the Honda CR-V (early 2007 to late 2012). It combines the exhaust manifold and catalytic converter in one unit, supplied by Redback.
A manifold catalytic converter integrates the exhaust manifold and the catalytic converter into a single bolt-on unit that mounts straight off the cylinder head. It is the first part of the exhaust, gathering the gases from each port and passing them through the catalyst that treats emissions before they reach the rest of the system. As a one-piece replacement it restores the factory manifold-and-cat arrangement when the original has cracked, blocked or failed an inspection, rather than changing the character of the exhaust. The C0021 is the Honda application of that part.
It is listed to fit the Honda CR-V from early 2007 to late 2012 per the listing. Catalytic converters are matched closely to engine and emissions calibration, so the right unit comes down to your exact variant. It is listed to fit this Honda; confirm the exact build with the workshop before ordering so the manifold flange and sensor bungs line up with your engine.
This is a manifold catalytic converter — it keeps the catalyst in the exhaust rather than removing it, which is the part that matters for emissions compliance on a road car. Replacing a failed unit with a like-for-like cat keeps that emissions hardware in place. Confirm the exact build and any inspection requirements with the workshop before fitting, as catalytic converters must match the vehicle’s original specification.
Oak Flats Muffler Men fits manifold catalytic converters in-house across the Illawarra. Because the unit bolts to the head, we check the manifold flange seals cleanly, transfer or fit the oxygen sensors into the correct bungs, and confirm clearances before signing it off. At an RRP of $539 it is a considered replacement; send your CR-V build and we’ll confirm the C0021 is the right unit and book the bay.
