Redback Headers.
Category: Extractors and headers


The Redback RBH034M is a set of headers listed to fit the Holden Commodore from 01/1988 to 01/2000 and the Calais from 01/1989 to 01/1997. It's a tubular replacement for the factory exhaust manifold on those models, listed at $1,569.
The RBH034M is a header set — sometimes called extractors — that bolts to the cylinder head in place of the cast factory manifold. It's the very front of the exhaust system, gathering gases from each cylinder into the rest of the pipework. This listing is the header set for the Commodore and Calais of the listed era; the rest of the system, cats and mufflers are separate items confirmed against the build.
Headers replace the restrictive cast manifold with separate tubes for each cylinder that merge further downstream. The idea is to let exhaust gas leave the head more freely than a one-piece casting allows. They're an engine-bay job and they change the very start of the exhaust path, which is why fitment to the specific head and engine matters more here than almost anywhere else in the system. We don't publish power or sound figures for them — those depend on the whole build.
It's listed to fit the Holden Commodore from 01/1988 to 01/2000 and the Calais from 01/1989 to 01/1997 — a long run that spans several variants. Confirm your exact model, engine and build with the workshop before ordering, since header fitment is sensitive to those details.
Oak Flats Muffler Men supplies and fits Redback headers across the Illawarra. We match the RBH034M to your Commodore or Calais, check clearances and flange fit in the bay, and confirm gaskets and hardware as part of the install.
