The MPI Automotive SSMBM467MF is the 3in rear muffler for the independent-rear-suspension Commodore sedan — the tail-end silencer shaped to clear the IRS cradle on the VP-VS cars. The IRS fitment is what sets this one apart.

Why an IRS-specific rear muffler?

The independent-rear-suspension sedans package their rear exhaust around a different cradle than the live-axle cars, so the rear muffler has to be shaped to suit. This unit is cut for the IRS body, which means its hanger points and clearances land correctly without fabrication. As a chambered muffler it sets the final tailpipe note by absorbing and reflecting pulses.

What does the 3in bore suit?

At 3in this rear muffler is matched to a V8 that's been opened up and wants flow through the back of the system, rather than a stock-size pipe. It's the larger-bore choice for a worked or free-breathing engine. MPI Automotive lists it for the Holden Commodore IRS sedan across the VP to VS range.

Will it suit my IRS Commodore?

It's listed to fit the Holden Commodore VP, VQ, VR and VS sedan with IRS. The suspension type is the deciding detail, so confirm your car is the IRS variant — and check the rest of your 3in system — with the workshop before ordering.

What does fitting involve in the Illawarra?

Oak Flats Muffler Men fits these rear mufflers in-house. We confirm the IRS clearance, that the 3in inlet matches your pipe, and that the muffler hangs square before we sign it off.

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

Common questions

Is the SSMBM467MF for IRS cars only?
Yes — it's the rear muffler cut for the VP-VS sedan with independent rear suspension.
Is this the centre or rear silencer?
It's the rear muffler — the last silencing stage before the tailpipe, where the final note is set.
Will it fit a live-axle Commodore?
No — it's shaped for the IRS cradle. A live-axle car needs the matching part for its body. The workshop can confirm your suspension type.
