The MPI Automotive HOLS128SR-3VFHSV-VBM is a matched pair of 3in rear mufflers for the VF HSV sedan with a vacuum bi-modal valve — a switching silencer that opens and closes a flap to change the note between quiet and loud.
What does the vacuum bi-modal valve do?
The defining feature here is the vacuum-operated bi-modal valve in each 3in rear muffler. A bi-modal muffler runs an internal flap that diverts gas between a quieter path and a freer-flowing one, switched by engine vacuum. Closed, it keeps the note subdued; open, it lets the rear section flow more directly for a harder character. That switchability is what sets this pair apart from a fixed rear muffler — you get two states from the one unit.
Why the 3in bore and the pair?
These are 3in mufflers, the larger bore suited to a higher-output or modified engine, supplied as a left-and-right matched set so both sides switch and flow together. On the VF HSV sedan the pair sits at the tail as the final silencing stage, with the valves controlling how open that stage is. We can't put a sound figure on either state — the honest way to judge it is to hear a comparable bi-modal fit.
Will it suit my VF HSV sedan?
It's listed to fit the VF HSV sedan. The sedan rear layout and the vacuum supply for the valves both shape the fitment, so confirm your exact build and that the vacuum control suits your car with the workshop before ordering. The 3in bore should also suit the pipe ahead.
How do we fit it in Illawarra?
Oak Flats Muffler Men supplies and fits the HOLS128SR-3VFHSV-VBM pair in-house across the Illawarra. We match each muffler to its hanger, set the exits even under the sedan, and confirm the vacuum bi-modal valves operate as intended before signing off. Bring the car in and we'll confirm fitment and book the work.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
