Holden VE/VF Commodore V8 Sedan Varex Valved Twin 3" Cat Back Exhaust System Special order.
Category: Complete exhaust systems


Listed for the Holden VE/VF Commodore V8 sedan, the Exhaust Systems Australia HOLDEN-VE-VF-COMMODORE-V8-SEDAN-VAREX-VALVED-TWIN-3-CAT-BACK-EXHAUST-SYSTEM is a twin 3in cat-back with a bi-modal Varex valve, priced at $2,550 and brought in to order.
This Varex-valved cat-back is matched to the sedan body of the V8 Commodore across the VE and VF generations, not the ute or wagon. It runs twin 3in pipework and finishes through a bi-modal valved muffler. At $2,550 it sits among the valved sedan options in this range. The stainless grade isn't published for this particular listing, so we don't quote it — it's confirmed against the kit at fitting rather than guessed at.
The valve adds a butterfly inside the rear muffler that opens or closes a silencing path. Closed, the sedan runs a quieter, more settled note; open, it bypasses for a louder one — usually switched from the cabin. That gives one cat-back two characters rather than a single fixed volume. No sound level is published, so we don't quote one.
A cat-back is the run behind the catalytic converter — the rear pipework and muffler — so the cat and the engine-side plumbing stay as Holden built them. The twin 3in tubing carries the gas from the cat back to the tips on the sedan, reworking the rear flow and note while leaving the emissions hardware up front untouched.
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 V8 Commodore sedan, which we confirm against your car first. On the hoist we hang both 3in pipes, wire in the valve control, check clearances under the rear bar, and confirm the valve switches cleanly here in the Illawarra.
