The Redback RBH040 is a set of headers listed to fit the Holden Commodore built between 1980 and 1984. It replaces the cast factory manifold with tuned tubing and carries a recommended retail of $725.
What is a header and what does it change?
A header, also called an extractor, replaces the one-piece cast exhaust manifold with separate primary tubes that merge into a collector. The point is to let each cylinder scavenge more freely than the factory casting allows, working at the front of the exhaust where gas first leaves the head. Anything behind the collector is a separate part of the system. Redback doesn't publish the tube diameter or material for the RBH040 in our data, so the workshop confirms the actual part against the listing rather than us quoting figures we can't trace.
Will it suit my Holden Commodore?
It's listed to fit the Holden Commodore from 1980 to 1984. That early Commodore run came with more than one engine, so the exact engine and body matter when matching a header set. Tell us what your Commodore runs and we'll check the RBH040 against the listing before anything is ordered.
Is it road legal?
Headers sit ahead of the silencing and emissions equipment, so legality depends on the complete system and how the car is presented for registration in NSW. We don't make a blanket compliance claim on a header set on its own — confirm your requirements with the workshop first so the right part goes on for how the car is registered.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits classic Commodore header sets in-house across the Illawarra. On a car this age we check the head studs and surrounding pipework while the old manifold is off, then fit the RBH040 with fresh gaskets and confirm clearances on the day. Book the Commodore in and we'll quote the labour alongside the part.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
