STR130HD is a pair of twin centre hotdog resonators for the Holden Commodore VT and VX, built in a 2in bore. Supplied by Redback, these are compact straight-through resonators that mount in the centre of a dual run to tune resonance without heavy silencing.
What does a twin hotdog setup do?
This is a twin assembly — two hotdog resonators, one per bank of a dual exhaust. A hotdog is a small straight-through resonator: a perforated core in packing that flows freely while cutting drone. Running them as a centre pair targets resonance on both pipes of a dual system at once, keeping the note tuned and the flow up through the middle of the run rather than choking it with chambered boxes.
What does the 2in bore suit?
At 2in these resonators are sized for the dual pipework on the VT-VX Commodore rather than a larger aftermarket bore. The size keeps gas speed sensible through the centre section. It's listed to fit the Holden Commodore VT and VX; because that spans two model updates, confirm your exact car and the rest of your dual pipework with the workshop.
Will it quieten the car?
Hotdogs tune more than they silence — they target drone and resonance rather than dropping overall volume the way a chambered muffler does. As a twin centre pair they manage the boom across both pipes while letting the system breathe. We can talk through how they work with your rear mufflers on the VT-VX.
What does fitting involve in the Illawarra?
Oak Flats Muffler Men supplies and fits this twin centre assembly in-house across the Illawarra. We set both hotdogs into the centre of your dual run, mate them to the existing pipework and check clearance and hangers. Bring your Commodore in and we'll confirm the fit and book it.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
