Rear hotdogs rather than full mufflers are the point of difference here: the Exhaust Systems Australia HOLDEN-COMMODORE-VT-VZ-5-7L-UTE-TWIN-2-1-2-REAR-HOTDOGS is a pair of 2in straight-through hotdog resonators in the rear position, listed for the VT–VZ 5.7L ute twin system.
What does a pair of rear hotdogs do?
A hotdog is a compact straight-through resonator — a short cylinder that tunes the note and trims drone without the volume drop of a full chambered muffler. Running hotdogs in the rear position on this 2in twin ute means the back of the system stays freer-flowing and louder than it would with full rear boxes, while still taking the harshest edge off the LS-era V8's note. It's the choice for an owner who wants a harder rear character on the 5.7L ute rather than a quiet finish.
How do rear hotdogs change the sound?
Because they flow straight through, hotdogs resonate and tune rather than heavily muffle, so a system finished on rear hotdogs is generally firmer in note than one with chambered rear mufflers. They smooth drone but don't drop volume the way a full box would. There's no published sound figure, so the honest test is to hear a comparable VT–VZ 5.7L ute fit before deciding — this is the louder, harder-edged path.
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 running the twin layout with the workshop before ordering — and that you want the harder rear-hotdog character rather than full mufflers.
How do we fit them at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits these rear hotdogs in-house across the Illawarra. We hang the pair on the ute's rear mounts, check they clear the tray and chassis, and join them square to the pipework ahead. Bring the ute in and we'll confirm fitment and book the bay.

Common questions
How are rear hotdogs different from rear mufflers?
Hotdogs flow straight through and tune the note, so they're firmer and louder than chambered rear mufflers, which silence more.
How many are in this part?
A pair — two 2in straight-through hotdogs in the rear position for the twin ute system.
Will it be loud?
Rear hotdogs sit on the louder, harder-edged side versus full mufflers. We can't quote a sound level — hear a comparable fit first.
