The MPI Automotive SSMBM478MF-E3-VBM is a pair of 3in dual rear mufflers for the HSV VE sedan 6.2L V8 (E3), fitted with OEM vacuum bi-modal valves. The factory-style vacuum bi-modal valving is the defining feature — it lets the note switch between quiet and loud using the car's own vacuum actuation.
What do the OEM vacuum bi-modal valves do?
Bi-modal mufflers run valves inside the rear cans that open and close to change the exhaust path. This unit uses OEM-style vacuum bi-modal valves, meaning they actuate the way the factory HSV system did — on vacuum rather than an added electric system. Closed, the exhaust takes the longer, more muffled route for a quiet cruise; open, it short-cuts to the freer path and the 6.2L V8 opens up. So the SSMBM478MF-E3-VBM gives a switchable note: a subdued floor and a louder ceiling on the same hardware, integrating with the VE's existing vacuum control.
How does the 3in dual rear layout suit the E3 sedan?
These are dual rear mufflers in 3in, sized for the 6.2L V8 and carrying both banks through matched valved cans at the back of the HSV VE sedan. As the rear section it sets the final note, working with the centre and front pipework the car already runs. It's listed to fit the HSV VE sedan 6.2L V8 in E3 spec; confirm your exact model and that your car has the vacuum bi-modal control with the workshop before ordering, since the valve actuation has to match.
Is it road legal?
This is a rear-muffler section. It doesn't include or delete the catalytic converter, so the cat-delete off-road rules don't apply to this part. A switchable louder setting can put a car outside noise limits depending on how it's used, so confirm the in-service note and any state requirements with the workshop before fitting.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits valved HSV rear sections in-house across the Illawarra, hanging the dual rears and checking the vacuum bi-modal valves connect to the car's existing actuation. The SSMBM478MF-E3-VBM carries a published RRP of $2,627.63; send your build and we'll confirm fitment and book the bay.
