A hotdog is a compact straight-through resonator, and this Exhaust Systems Australia part (HOLDEN-COMMODORE-VN-VS-V8-SEDAN-2-1-2-CENTRE-HOTDOG) is exactly that — a centre hotdog listed to fit the VN–VS Commodore V8 sedan. It's the small, free-flowing mid-section unit, not a full chambered muffler.
What does a centre hotdog do?
A hotdog is a short, straight-through resonator that sits in the centre of the system. It takes a little edge off the note and reduces drone without the volume drop or flow restriction of a full chambered muffler. On a VN–VS V8 sedan it's the part you fit mid-pipe when you want the system to breathe while keeping resonance in check — a tuning device more than a silencer.
Where does it sit in the system?
This is the centre unit only, sized for the listed 2in pipework. It replaces or adds the mid-section resonator and leaves the rest of the exhaust as fitted. Because it's straight-through, it flows freely and is commonly paired with a rear muffler that does the main quietening — the hotdog handles drone in the middle of the car.
Will it suit my Commodore?
It's listed to fit the Holden Commodore VN–VS V8 sedan. Send your build through and we'll confirm the bore and centre-section length match your pipework before ordering — at $170 RRP it's an inexpensive way to manage mid-range resonance.
What does fitting involve at Oak Flats?
Oak Flats Muffler Men fits centre hotdogs in-house across the Illawarra. We confirm the inlet/outlet match your 2in system, position it for clearance over the tunnel, and weld it in. Being a single small unit it's a quick job and a cheap way to settle a droning V8 mid-section.

Common questions
Is a hotdog the same as a muffler?
No. A hotdog is a compact straight-through resonator that cuts drone and flows freely, where a chambered muffler is built to quieten more. They're often used together.
Will it make my V8 louder?
It's straight-through, so it's free-flowing rather than a heavy silencer. The rear muffler sets most of the volume; the hotdog mainly manages mid-range drone.
Does it fit a VN–VS Commodore?
It's listed to fit the VN–VS Commodore V8 sedan. Confirm your pipework bore with Oak Flats Muffler Men before ordering.
