Running twin Everflo mufflers, the Exhaust Systems Australia HOLDEN-COMMODORE-VS-V6-SEDAN-IRS-2-1-2-CATBACK-KIT-INC-2-X-EVERFLO-MUFFLERS is a 2in cat-back kit for the IRS-equipped VS Commodore V6 sedan — a two-muffler layout that leans toward a settled note rather than a single big box.
What does the twin-muffler layout do?
This kit carries two Everflo mufflers in the cat-back run instead of one. Splitting the silencing across two boxes spreads the work, which tends to keep the note controlled on a V6 sedan that's spending most of its life on the street. As a cat-back it replaces everything from the catalytic converter back, so the factory emissions hardware up front stays untouched and the change is to flow and tone behind it.
Why does the IRS callout matter?
The VS sedan was offered with both live-axle and independent rear suspension, and the rear routing differs between them. This kit is the IRS version, so the pipework and hangers are shaped to clear the independent rear cradle rather than a live axle. That's the detail to get right — an IRS kit won't sit cleanly under a live-axle car, which is why we confirm your rear end before ordering.
Will it suit my VS Commodore V6 sedan?
It's listed to fit the Holden Commodore VS V6 sedan with IRS, built on a 2in bore. Confirm your exact build — IRS versus live axle, and sedan versus any other body — with the workshop before ordering.
How do we fit it in the Illawarra?
Oak Flats Muffler Men supplies and fits this cat-back kit in-house across the Illawarra. We hang both Everflo mufflers, line the 2in pipework through the IRS cradle and set the rear clearance so nothing knocks on the body. Bring the VS in and we'll confirm fitment and book the bay.
