The Exhaust Systems Australia HOLDEN-HK-HT-HG-V8-SMALL-BLOCK-CHEV-283-400-GENIE-EXTRACTOR-1968-TO-1971 is a set of Genie extractors listed to fit the Holden HK, HT, and HG with the small-block Chev V8 (283 to 400) from 1968 to 1971.
What are extractors and what do they change?
Extractors, also called headers, replace the cast factory exhaust manifolds with separate tubular runners from each cylinder. The aim is to let the V8 breathe out with less restriction than the cast manifolds. It's a change to the exhaust side of the engine rather than an internal part, and it sits at the front of the system feeding everything behind it.
What does the small-block Chev listing tell us?
These extractors are listed for the small-block Chev V8 across the 283 to 400 range, fitted to the Holden HK, HT, and HG from 1968 to 1971. That covers a span of small-block sizes in those early Holdens, so the exact engine and body are what the fitment is matched to. The 283 to 400 figures are the engine range on record for this set.
Will it suit my Holden?
It's listed to fit the Holden HK, HT, and HG with the small-block Chev V8 from 1968 to 1971. Because these are older cars and a range of engine sizes, confirm your exact body, year, and engine with the workshop before ordering, so the right set goes on.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits Genie extractors like these in-house across the Illawarra. On these early Holdens the job means good access to drop the cast manifolds, fresh gaskets, and matching the extractor outlet to the system behind it. Supplied by Exhaust Systems Australia at $1,155.00 AUD; send your car's details and we'll confirm the fit and book the bay.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
