The MPI Automotive MBM124MF is a dual centre-muffler set built for the twin-cat layout on the IRS Holden Statesman V8. Running two bodies side by side rather than a single centre can, it keeps the factory dual-path routing intact behind the catalytic converters.

Why a dual centre-muffler set off twin cats?

On a V8 Statesman with independent rear suspension and a twin-catalytic-converter front end, the exhaust splits into two banks early and stays split. The MBM124MF is supplied as a matched pair of centre mufflers so each bank carries its own silencing through the middle of the car. That preserves the original dual-path character the platform was engineered around, rather than collapsing both sides into one shared chamber. The bodies sit in the centre section, after the cats and ahead of the rear, where most of the resonance is taken out of the system.

What does a centre muffler change on this car?

A centre muffler does the bulk of the work taming the mid-frequency boom you hear at cruise. Swapping the pair lets you renew tired, rusted-through factory silencing or set the note to suit, while leaving the catalytic converters and rear section in place. Because it is a like-for-like dual replacement, it is the sensible repair when one or both original centre cans have rotted out but the rest of the system is sound.

Will it suit my Holden Statesman?

The MBM124MF is listed to fit the IRS V8 Holden Statesman with the twin-cat arrangement. Statesman trim and rear-end specification changed across the range, so confirm your exact build with the workshop before ordering — the dual layout has to line up with what is already under your car.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this set in-house. We check the existing hangers, the cat-back joins on both banks and the clearance to the IRS cradle, then mount each muffler so the dual path stays even side to side. Send your VIN or build details and we will confirm fitment and book the bay.

Common questions

Is the MBM124MF one muffler or a pair?
It is a dual centre-muffler set — two bodies, one per bank, to match the twin-cat layout on the IRS Statesman V8.
Does it keep my catalytic converters?
Yes. This set fits in the centre section behind the twin cats, so the factory catalytic converters and the rear section stay in place.
Will it fit my exact Statesman?
It is listed to fit the IRS V8 Statesman with twin cats. Confirm your specific build with the workshop, as rear-end and exhaust routing varied across the range.
