This kit pairs a hotdog resonator with a single Everflo rear muffler: the HOLDEN-COMMODORE-VT-VY-V6-SEDAN-2-1-2-CATBACK-KIT-INC-HOTDOG-EVERFLO-MUFFLER from Exhaust Systems Australia is a 2in cat-back that uses the hotdog to tune drone and the rear muffler to set the final note. It's listed to fit the Holden Commodore VT–VY V6 sedan.
How do the hotdog and rear muffler split the work?
The two silencers do different jobs. The hotdog is a compact straight-through resonator that targets resonance and drone without choking flow, while the Everflo rear muffler handles the bulk of the volume at the tail. Running both means the centre of the car stays settled and the final note is set by the rear box — a tidier result than asking one muffler to manage everything on a single-pipe VT–VY six. The system is built on a 2in body to suit the standard or lightly worked V6.
What does a cat-back kit replace?
A cat-back swaps the whole run from the catalytic converter back — pipe, resonator, muffler and tailpipe — so the factory cat and the emissions hardware ahead of it stay in place. As a complete kit it's supplied to fit as a section rather than piecing it together box by box, which makes it the straightforward reset when the rear of an older Commodore system is worn out.
Will it suit my VT–VY Commodore?
It's listed to fit the Holden Commodore VT through VY V6 sedan — the single-pipe sedan routing and hanger spacing are particular to that body. Wagons and utes run their own kits, so confirm your exact build with the workshop before ordering to make sure this hotdog-plus-muffler kit is the right one for your car.
How do we fit it at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits this kit in-house across the Illawarra. We set the hotdog in the mid-section, hang the Everflo rear muffler on the sedan hangers, and check clearance to the floor and rear suspension before lining the tailpipe up. Bring the car in and we'll confirm fitment and book the bay.

Common questions
What's the difference between the hotdog and the muffler here?
The hotdog is a small straight-through resonator that tackles drone; the Everflo rear muffler sets the final volume at the tail. The kit runs both.
Does it keep the catalytic converter?
Yes — it's a cat-back kit, so it replaces from the catalytic converter back and leaves the factory cat in place.
Will it fit a VT–VY wagon?
It's listed for the VT–VY V6 sedan. Wagons run a different kit, so confirm your exact body with the workshop.
