This XForce-tuned extractor system, supplied by Exhaust Systems Australia, is listed to fit the Holden Commodore VT-VZ V8 and pairs 1-3/4 headers with cats in a matte 409 finish. It's a special-order item. The MPN is HOLDEN-COMMODORE-VT-VZ-V8-XFORCE-TUNED-1-3-4-HEADER-3-CATS-MATTE-FINISH-409.
What does this part cover?
This is an XForce-tuned header-and-cat package for the Holden Commodore VT to VZ V8, built with 1-3/4 primaries, cats, and a matte 409 finish. It combines the extractors with the catalytic converters into the one system for that engine. It's catalogued as a special-order item, so it's brought in to order rather than held on the shelf.
What's a tuned header set with cats and what does it change?
Extractors replace the cast manifolds with tuned-length tubes; running the cats in the same package keeps the emissions hardware in place rather than deleting it. A 1-3/4 primary is a common size for a V8 of this era, and 409 is a stainless grade often chosen for exhaust work. The supplier publishes no power or sound figures, so we don't quote any — what we can state is the design, the cats and the finish.
Will it suit my Holden Commodore?
It's listed to fit the Holden Commodore VT through VZ V8. Treat that as listed to fit rather than guaranteed, since feed data can be imperfect. As a special-order item, it pays to confirm the exact build, finish and lead time with the workshop before committing to the order.
Is it road legal?
This package keeps the catalytic converters rather than deleting them, so it's built to retain the emissions hardware. Any state compliance requirements should still be confirmed against your specific vehicle with the workshop. Oak Flats Muffler Men supplies and fits XForce systems across the Illawarra; at $1,350 AUD RRP and special order, book in early so we can confirm the build and lead time.
