At $2,899 recommended retail, the Exhaust Systems Australia HOLDEN-VE-VF-COMMODORE-UTE-V8-304-TWIN-3INCH-VAREX-VALVED-CAT-BACK-SYSTEM pairs a bi-modal Varex valve with twin 3in 304 stainless pipework for the Holden VE/VF Commodore V8 ute.
What does the Varex valve do here?
This V8 ute system's headline feature is its bi-modal Varex valved muffler. The valve opens or closes an internal path so the exhaust runs a quieter note when shut and a louder one when open — usually switched from the cabin — letting one system suit both a settled cruise and a livelier drive. It's the valved counterpart to the fixed 304 twin 3in ute cat-back in this range, which is why it sits at the higher $2,899 price.
Will it suit my Holden Commodore V8 ute?
It's listed to fit the Holden VE and VF Commodore V8 ute. We treat that as listed-to-fit rather than guaranteed, since feed data can be imperfect, and confirm your year and variant before ordering. The V8 driveline and ute body are both called out in the listing, so it's matched to that combination.
Where does a twin 3in cat-back sit in the system?
A cat-back is the run behind the catalytic converters — the rear pipework and muffler — so the cats and the manifolds ahead of them stay factory. Built in corrosion-resistant 304 stainless and splitting to twin 3in through to the rear of the ute, this kit reworks the rear flow and note while leaving the emissions hardware up front in place.
What's involved in ordering and fitting at our Illawarra workshop?
As a special-order item, Oak Flats Muffler Men brings this in for your booking — ask us for the lead time. On the hoist we hang both 3in pipes, wire in the valve control, set clearance over the rear axle and tray, and confirm the valve switches cleanly before sign-off here in the Illawarra.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
How is the note controlled?
Through a bi-modal Varex valved muffler — quieter with the valve shut, louder with it open, usually switched from the cabin. No sound level is published, so we don't quote one.
Does it keep the catalytic converters?
Yes. As a cat-back it only replaces the exhaust behind the catalytic converters, so the factory cats stay in place.
Is it a stocked part?
No. It's a $2,899 special-order item brought in for your VE/VF Commodore V8 ute booking. Ask the workshop for the current lead time.
