The Exhaust Systems Australia HOLDEN-VE-VF-COMMODORE-V8-304-TWIN-2-5INCH-VAREX-VALVED-CAT-BACK-SYSTEM is a $2,850 special-order cat-back for the Holden VE/VF Commodore V8 — twin 2.5in 304 stainless pipework with a switchable bi-modal Varex valve.
It's listed for the Holden VE and VF Commodore with the V8, with no single body style called out, so confirm your exact variant and year with the workshop before ordering. We treat the listing as listed-to-fit rather than a promise, because feed data can be imperfect and the rear routing varies between the Commodore's body styles. That build check happens before anything is brought in.
This system is built in 304 stainless — the chrome-bearing, corrosion-resistant grade that holds up well against road salt and moisture — and runs twin 2.5in pipework through the rear section. The 2.5in bore sets how freely the back half flows on the V8, and the 304 construction is what places it at the $2,850 mark against leaner-grade alternatives.
The Varex valve sits in the rear muffler and opens or closes an internal path, so the exhaust runs a quieter note with the valve shut and a louder one with it open — usually switched from the cabin. Because it's a cat-back, the factory cats and the manifolds ahead of them stay in place; only the rear section behind the converters is replaced. No sound figure is published, so we don't quote one.
Oak Flats Muffler Men orders this special-order system in for your booking — ask us for the lead time. On the hoist we hang both 2.5in pipes, wire in the valve control, set the tips square under the rear bar, and confirm the valve switches cleanly here in the Illawarra.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
