RRP AUD 965, the XForce E4-HV20-2-CBS is a 2.5in dual cat-back in 304-stainless, listed to fit the Holden Commodore (VT-VZ). The dual-2.5 layout in 304 is the detail that defines this version against the others in the HV20 line.

What's specific to this version?

This is the E4-HV20-2-CBS at AUD 965, a 2.5in dual catback built in 304-stainless for the Holden Commodore across VT-VZ. The slug also references a 409-stainless catback variant, so confirm with us which stainless grade your order needs — the part on record here is the 304-stainless dual-2.5 system.

Will it suit my Holden Commodore?

It's matched to the Holden Commodore over the VT-VZ generations. Listed fitment is a starting point, not a promise across every body and build in that run, so give us your exact model, year and body and we'll check it against the E4-HV20-2-CBS before ordering.

What does the 304-stainless build mean?

304-stainless is a corrosion-resistant grade well suited to a long-life exhaust, which is the material called out for this listing. As a cat-back it replaces the rear section behind the catalytic converter in a dual-2.5 routing, leaving the factory cat and the emissions hardware ahead of it untouched. The note is fuller and louder than the original rear system.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits Commodore cat-backs in-house across the Illawarra. We confirm the 304-stainless dual-2.5 system against your car, check both pipes clear and sit on the hangers, and book the bay once the fitment is verified.
