These Exhaust Systems Australia Tri-Y extractors (MPN HOLDEN-COMMODORE-VE-6L-6-2L-V8-TRI-Y-GENIE-HEADERS-EXTRACTORS) are listed to fit the Holden Commodore VE with the 6L V8. The Tri-Y design is the headline here: a tuned-length pattern aimed at the gen-pushrod V8 rather than the cast factory manifolds.
What are extractors and what do they change?
Extractors replace the engine's cast exhaust manifolds with separate tubular primaries that merge into a collector. The idea is to give each cylinder a cleaner path out and reduce the back-pressure of a one-piece casting. On a V8 like the VE's, that's the first link in the exhaust, sitting between the heads and the rest of the system. A Tri-Y layout pairs the primaries in two stages before the collector, a pattern builders favour for spreading the benefit across the rev range rather than chasing top-end only. We won't quote power or sound figures — none are published by the supplier — but the part type itself is a manifold swap, not a full system.
Will it suit my Holden Commodore?
It's listed to fit the Holden Commodore VE running the 6L V8. Commodore V8s changed across the VE life and engine bays vary with accessories, so this is a confirm-before-you-commit fitment. Send us your exact build and we'll check it against the listing before anything is ordered.
Is it road legal?
These are extractors only — a manifold-area change, not a catalytic converter delete. Emissions compliance depends on what the rest of your exhaust does and on your state's requirements, so we'll talk through the NSW position with you rather than make a blanket claim. The supplier publishes no compliance approval and we won't imply one.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits extractors like these in-house in the Illawarra. Header swaps on a V8 mean working around steering, sump and crossmember clearances, fresh gaskets and a proper seal at the collector. We confirm the part against your VE first, then book the bay. Listed RRP is 1290 AUD; final fit-up is quoted once we've seen the car.

Common questions
Will these extractors fit my VE Commodore?
They're listed to fit the Holden Commodore VE with the 6L V8. We confirm your exact engine and build against the listing before ordering.
What is the Tri-Y design?
Tri-Y refers to the way the primary tubes are paired in two stages before the collector. The listing names it as a Tri-Y extractor; we don't publish power or sound numbers for it.
Are these a full exhaust system?
No. They are extractors that replace the factory exhaust manifolds. The rest of the exhaust is separate.
