The Redback RBH700 is a set of headers listed to fit the Holden Commodore and Calais from 2004 through 2006. It replaces the cast factory exhaust manifolds on these Holdens, with a Redback RRP of $1,119.
What are headers and what do they change?
Headers, also called extractors, swap the engine's cast exhaust manifolds for tubular primary pipes that gather into a collector. They bolt straight to the cylinder head, so they sit at the very front of the exhaust before any pipework, cat or muffler. That makes them the manifold-stage change: the point where each cylinder gets a less restrictive exit than the cast original. The RBH700 covers the headers for the listed Commodore and Calais; the supplier doesn't publish pipe diameter or material for this listing, so those are confirmed on the part rather than assumed here.
Will it suit my Commodore or Calais?
This set is listed to fit the Holden Commodore and Calais from 2004 to 2006. Because Holden ran several drivetrains across that body, the sensible check before ordering is matching your exact engine and variant to the listing rather than going by year alone. Treat it as 'listed to fit' and confirm your build with the workshop, since feed data can be imperfect and the manifold that's actually on your car is what the headers have to bolt to.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits headers like the RBH700 in-house across the Illawarra. On a 2004–2006 Commodore that means checking the head and gasket faces, the manifold studs, and clearance in the engine bay before the swap, then making sure the collectors tie cleanly back into the existing system. We confirm the fitment against your actual car before the part goes near the bay.
What does it cost and is it a stock item?
The RBH700 lists at a Redback RRP of $1,119. Application-specific headers like this aren't always held on the shelf, so it may come in as a special order — we'll confirm current availability and lead time when you book the work.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
