The Everflo HOLDEN-COMMODORE-VT-VZ-5-7L-UTE-TWIN-2-1-2-REAR-MUFFLER-EVERFLO from Exhaust Systems Australia is the 2in rear muffler for the VT–VZ 5.7L ute running a twin system. It's the rear silencer that sets the final tailpipe note behind the tray.
Where does this rear muffler sit?
On the VT–VZ 5.7L ute twin system, the Everflo is the rear stage — the box at the back end of the run, after the front and centre sections. Built on a 2in body, it's the silencer that shapes what you actually hear standing behind the tray. Being the rear muffler on a twin layout, it works on the final note of the LS-era V8 rather than the mid-range, and replaces just the rear box without disturbing the rest of the system.
What does the rear muffler change?
A muffler quietens by absorbing and reflecting sound inside its body. In the rear position the Everflo tempers the tailpipe character at the very end of the system, so it's the box that most affects how the ute sounds to someone behind it. There's no published sound figure, so the honest way to judge it is to hear a comparable VT–VZ 5.7L ute twin fit before deciding.
Will it suit my 5.7L ute?
It's listed to fit the Holden Commodore VT through VZ 5.7L ute on a twin 2in system. The ute rear mounting and tray clearance are specific to that body, so confirm your exact model and that you're on the twin layout with the workshop before ordering — the sedan and wagon sit differently at the back.
How do we fit it at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits the Everflo rear muffler in-house across the Illawarra. We hang it on the ute's rear mounts, check the body clears the tray and chassis, and join it square to the pipe ahead. Bring the ute in and we'll confirm fitment and book the bay.
