Which Commodore does the E4-VF73SED-CBS fit?

It's listed to fit the Holden Commodore V8 sedan. Confirm your exact year and variant with the workshop before ordering.

Is the catalytic converter retained?

Yes — a cat-back replaces the system from behind the catalytic converter back, so the factory cat stays in place.

Priced at $1,899 RRP, the XForce E4-VF73SED-CBS is a cat-back exhaust listed to fit the Holden Commodore V8 sedan. It's a rear-section system supplied and fitted at our Illawarra workshop.

Will it suit my Holden Commodore V8?

The listing records the Commodore model, the V8 engine and the sedan body, with Holden named among the mentioned makes. No year is set for this VF73-coded part, and fitment feeds can carry small errors, so the model and body are the firm details and the rest we confirm against your car. Send your Commodore's build and we'll match it before ordering.

What does this cat-back replace?

Being a cat-back, the E4-VF73SED-CBS swaps the exhaust from the catalytic converter rearward and keeps the factory cat and engine-side pipework in place. The supplier doesn't publish the pipe diameter or material for this listing, so we read those off the kit at fitting instead of quoting a bore or grade that isn't on record.

What's the trade-off with a V8 cat-back?

Because the change sits behind the cat, this is a rear-half upgrade rather than a full engine-back one — a cleaner install that alters the back-half flow and note while leaving the emissions hardware standard. On a V8 Commodore it tends to give a fuller sound than stock. No sound or flow figures are published here, so we won't characterise it beyond that.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits XForce cat-back systems in-house across the Illawarra. We offer the part up to your V8 Commodore, confirm the rear pipework clears the underbody and hangers, and book the bay once it's verified. The recommended retail price is $1,899.
