The SSMBM418MF is a dual 3in centre muffler assembly for the IRS Holden Commodore VP–VS V8 sedan, set up to run off a twin-cat front — the mid-system silencing for cars with two catalytic converters feeding into it.
What does 'off twin cat' mean here?
This centre assembly is configured to pick up from a twin-catalytic-converter front, where each bank of the V8 runs its own cat before the gas reaches the centre. The dual 3in centre mufflers then take that twin feed and silence it mid-system, matched to the geometry of a twin-cat VP–VS sedan rather than a single-cat layout.
Why the IRS and dual-centre arrangement?
The independent-rear VP–VS sedans route the centre differently to live-axle cars, and the dual centre keeps both banks separate through the middle of the run. Built to a 3in bore, the assembly suits a larger twin system, doing the main silencing before the rear while clearing the IRS subframe.
Which models is it listed for?
It's listed to fit the Holden Commodore VP through VS V8 sedan with IRS and a twin-cat front. Confirm your exact model, rear setup and that you have the twin-cat arrangement with the workshop before ordering — single-cat cars need a different part.
What does fitting involve in the Illawarra?
Oak Flats Muffler Men supplies and fits the MPI Automotive SSMBM418MF in-house across the Illawarra. As a centre assembly we mock it on the hoist, confirm both sides pick up the twin-cat feed and clear the IRS subframe, and weld or clamp it in. Send your model and we'll confirm fit.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Does the SSMBM418MF suit a twin-cat car?
- Yes — it's configured to run off a twin catalytic-converter front on the IRS VP–VS V8 sedan. Single-cat cars use a different assembly. Confirm your setup with the workshop.
- Is this a centre or rear assembly?
- A dual centre muffler assembly — it does the mid-system silencing, not the rear tailpipe section.
