Twin hotdogs with an X-pipe crossover define this centre section: the Exhaust Systems Australia HOLDEN-COMM-VT-VZ-5-7L-UTE-STATESMAN-TWIN-2-1-2-CM-WITH-HOTDOGS-AND-X-PIPE is a 2in twin mid-section using compact straight-through hotdogs, listed for the VT–VZ 5.7L ute and Statesman.
What is a hotdog-and-X-pipe centre section?
A hotdog is a compact straight-through resonator — a short cylinder that smooths the note and trims drone without the volume drop of a full chambered muffler. The X-pipe is a crossover that links the two banks mid-system, blending the pulses so the twin sound evens out. On this 2in twin centre section they form the mid-system tuning stage rather than a heavy silencer, which is why this part suits owners chasing a clean, even twin note. It's listed for the 5.7L ute and the Statesman.
How do the hotdogs change the sound?
Because hotdogs flow straight through, they tune and resonate rather than heavily muffle, taking the edge off drone while keeping the system freer than a chambered box. The X-pipe further smooths things by sharing flow between banks. There's no published sound figure, so the honest test is to hear a comparable VT–VZ 5.7L twin fit — this is a tuning stage, not the final say on volume.
Will it suit my 5.7L ute or Statesman?
It's listed to fit the Holden Commodore VT through VZ 5.7L ute and the Statesman, in a twin 2in layout. The centre-section length and crossover position differ between bodies, so confirm your exact model and that you're running the twin layout with the workshop before ordering.
How do we fit it at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits this hotdog-and-X-pipe centre section in-house across the Illawarra. We set the X-pipe crossover square, hang the two hotdogs clear of the floor and chassis, and line the section up to the front and rear stages. Bring it in and we'll confirm fitment and book the bay.
