This is the rear muffler on its own, not a full kit: the HOLDEN-COMMODORE-VT-VY-V6-ALL-MODELS-2-1-2-REAR-MUFFLER-EVERFLO from Exhaust Systems Australia is a single Everflo rear muffler on a 2in body. It's the tail box for the Holden Commodore VT–VY V6 across all models.
What does the rear muffler do?
The rear muffler is the last silencer in the system — the box at the tail that sets the final note as gas exits. A muffler quietens by absorbing and reflecting sound inside its body, so replacing just this box lets you reset the tailpipe character of a VT–VY six without touching the centre section. It's built on a 2in body to suit the standard or lightly worked V6, supplied as a single component rather than a complete cat-back.
When do you replace just the rear box?
Swapping only the rear muffler is the focused move when the tail box is the part that's tired, rusted or rattling, or when you want to change the final note while keeping the rest of the system. It's a smaller job and a smaller spend than a full kit. We can't put a number on the sound — there's no dB data — so the honest test is to hear a comparable VT–VY fit before you commit.
Will it suit my VT–VY Commodore?
It's listed to fit the Holden Commodore VT through VY V6 across all models — the rear muffler position is common to that range, but body-specific routing still matters, so confirm your exact car and that you need the rear box rather than a full kit with the workshop before ordering.
How do we fit it at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits this rear muffler in-house across the Illawarra. We hang it on the rear hangers, check clearance to the floor and rear suspension and join it square to the pipe ahead so it sits without strain. Bring the car in and we'll confirm fitment and book the bay.
