Built for the splitting point in a dual system: the MPI Automotive MBM120MF is a pair of 2in centre mufflers that run off a single catalytic converter on the IRS-sedan Holden Commodore VP, VQ, VR and VS. It takes one inlet and feeds two silenced centre sections, the classic dual-rear layout for these cars.

What does this dual-off-single arrangement do?

These VP–VS Commodores route a single front pipe and cat into a split that feeds two rear pipes. The MBM120MF supplies the two centre mufflers for that split — chambered silencers that take the single feed and quieten each side before the tailpipes. It's the part that turns a single mid-section into a balanced dual without re-engineering the front of the car.

Will it suit my VP–VS Commodore?

It's listed to fit the IRS-sedan VP, VQ, VR and VS Commodore. Independent-rear-suspension cars route differently to the live-axle versions, so the IRS qualifier matters here. Confirm your body and rear-end with the workshop, as feed data can be imperfect and we'd rather check than guess.

Why centre mufflers rather than a rear-only change?

Centre silencing sets the baseline tone of the car before the rear mufflers or tips colour it. Replacing this pair lets you renew tired factory centre boxes or set the system's character from the middle out, keeping the dual-rear look these sedans wore from the factory.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits centre muffler pairs like this in-house across the Illawarra. We confirm the single-cat feed and the dual split line up, check hanger positions on the IRS subframe, and book the bay once the fit is verified against your car.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.

How many mufflers come in the MBM120MF?
