The XForce E4-HV20-1-CBS is a cat-back performance exhaust listed to fit the Holden Commodore VT to VZ sedan. It's the rear-section upgrade, supplied and fitted at our Oak Flats workshop in the Illawarra.

What does this system cover?

This is a cat-back for the VT-VZ Commodore sedan, replacing the exhaust from the catalytic converter back. The factory cat and front pipework stay; only the rear section changes. XForce don't publish a pipe diameter, material or muffler spec for this part in our records, so we don't quote them — they're confirmed against the kit at fitting.

What's a cat-back and what does it change?

A cat-back is the run behind the catalytic converter, so swapping it reworks the rear flow and the note without touching the emissions hardware up front. Across the VT to VZ Commodore sedans it's the contained way to freshen the back of the exhaust. Because the cat stays standard, the change is limited to the rear section.

Will it suit my Holden Commodore?

It's listed to fit the Holden Commodore VT to VZ in sedan body. We don't hold the exact engine for this part, and feed data can be imperfect, so treat the fit as "listed to fit" and confirm your specific variant with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits XForce cat-back systems like this in-house. We check the listed fitment against your sedan, confirm the rear pipework clears the underbody and hangers, and book the bay. The recommended retail price is $995. Send your Commodore details and we'll confirm the build first.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
