Redback Headers.
Category: Extractors and headers


The Redback RBH327 is a set of extractors listed to fit the Holden Commodore VE and VF V8, with 1-7/8in primaries and a 3in outlet. It replaces the cast factory manifolds on the late V8 Commodore, at a Redback RRP of $1,689.
Extractors, also called headers, swap the engine's cast exhaust manifolds for tubular primaries that gather into a collector on each bank. They bolt to the cylinder heads, so they're the first stage of the exhaust. On this set the primaries are 1-7/8in and they finish at a 3in outlet, meaning the pipe size where they hand off to the rest of the system. That's the manifold-stage change people make on a V8 to give each cylinder a less restrictive exit than the cast original.
The RBH327 is listed to fit the Holden Commodore VE and VF in V8 form — the late-model V8 Commodores. The check is confirming you have the V8 in one of those two models, since extractor fitment follows the engine and head. Treat the listing as 'listed to fit' and confirm your exact build with the workshop before ordering, particularly the 3in outlet match to whatever system follows.
Oak Flats Muffler Men supplies and fits extractors like the RBH327 in-house across the Illawarra. On the VE/VF V8 that means checking head and gasket faces and clearance before the swap, then making sure the 3in outlet ties cleanly into the system behind it.
The RBH327 lists at a Redback RRP of $1,689. V8 extractor sets aren't always shelf stock, so it may come in as a special order — we'll confirm current availability and lead time when you book the bay.
