Sized at twin 3in and built in 304 stainless, the Exhaust Systems Australia HOLDEN-VE-VF-COMMODORE-V8-304-TWIN-3INCH-VAREX-VALVED-CAT-BACK-SYSTEM is the large-bore valved cat-back for the Holden VE/VF Commodore V8, listed at $2,899.
What does the large 3in bore bring on the V8?
This is the wider-bore 304 stainless cat-back for the VE/VF Commodore V8, running twin 3in pipework through the rear section. A larger bore gives the back half more room to flow, which is why this larger-tube build sits at the top of this 304 valved range at $2,899. It's built in 304 — the corrosion-resistant grade — and pairs that pipework with a switchable Varex valve.
How does the bi-modal Varex valve behave?
The Varex valve opens or closes a path inside the rear muffler, so the system runs a quieter note with the valve shut and a louder one with it open, usually switched from the cabin. That gives one cat-back two modes rather than a single fixed volume. No sound level is published for this listing, so we don't quote one — what's listed is the valved bi-modal layout in 304.
Where does a cat-back sit, and what stays factory?
A cat-back replaces the exhaust from behind the catalytic converters back to the tailpipes, so the cats and the manifolds ahead of them stay as Holden built them. On this V8 the twin 3in run splits to two pipes through to the rear, reworking the rear flow and note while leaving the emissions hardware up front untouched.
What's involved in ordering and fitting at our Illawarra workshop?
Oak Flats Muffler Men brings this special-order system in for your booking — ask us for the lead time. It's listed to fit the VE/VF Commodore V8, which we confirm against your car first. On the hoist we hang both 3in pipes, wire in the valve control, set the tips square under the rear bar, and confirm clean switching here in the Illawarra.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- What bore and grade is it?
- Twin 3in pipework in 304 stainless steel, with a bi-modal Varex valved muffler.
- Does it keep the catalytic converters?
- Yes. As a cat-back it only replaces the section behind the catalytic converters, so the factory cats stay in place.
- Is it ordered in?
- Yes. It's a $2,899 special-order item for the VE/VF Commodore V8. Ask the workshop for the current lead time.
