The Redback RBH700 is a set of headers listed to fit the Holden Commodore from 2004, with the Calais of the same period noted alongside it. It replaces the factory manifold at the front of the exhaust.
What's a header set and what does it change?
Headers replace the cast factory exhaust manifold with tubular runners that keep each cylinder's pulse separate before merging downstream. The aim is lower back-pressure and cleaner scavenging than a compact factory casting allows. On a mid-2000s Commodore that means a firmer note and freer flow at the front of the system, though headers are one component — they work with whatever cats and rear sections the car runs.
Will the RBH700 suit my Holden Commodore?
It's listed to fit the Holden Commodore from 2004, with the era's Calais referenced. Engine variants and emissions hardware differed across these cars, so the listing is a starting point. Send us your exact build and we'll confirm this header set matches before ordering.
What's the price and how is it supplied?
Supplied by Redback, the RBH700 carries a recommended retail price of $1,119 AUD. As a front-of-system part it's commonly fitted alongside a cat or rear-section refresh, so it's worth discussing the whole exhaust when you book.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits headers in-house across the Illawarra. We check the head flanges, gaskets, oxygen-sensor positions and surrounding clearances on these Commodores, then book the bay once the part is confirmed as correct for your car.
