The Redback RBH003 is a set of headers listed to fit the Holden Commodore from 1986. The slug also references the Calais of the same era, so it's aimed at the mid-1980s Commodore range.
What does a set of headers do?
Headers, or extractors, replace the factory cast manifold with tubular runners that gather each cylinder's exhaust pulse separately before merging. That reduces back-pressure at the front of the system and lets the engine scavenge more cleanly than a compact factory casting. On a mid-1980s Commodore it's a traditional breathing upgrade — it firms up the note compared with stock and frees the front of the exhaust, but it's one part of the system rather than the whole thing.
Will the RBH003 suit my Holden Commodore?
It's listed to fit the Holden Commodore from 1986, with the era's Calais noted alongside it. Engine and emissions fitments varied across these cars, so treat the listing as a starting point. Send us your exact build and we'll confirm this header set is correct before it's ordered.
What's the price and supply?
Supplied by Redback, the RBH003 has a recommended retail price of $875 AUD. On an older car like this, headers are often fitted as part of a wider exhaust tidy-up, so it's worth discussing the rest of the system when you book.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits headers in-house across the Illawarra. On a 1980s Commodore we check the head flanges, gaskets, steering shaft and starter clearances before fitting, and book the bay once the part is confirmed for your car.
