The Redback STR105 is a 2.5in centre muffler listed to fit the Holden Commodore VP and VS sedan with IRS. It sits in the middle of the system, not at the tail, and is built specifically for the independent-rear-suspension cars.
What does a centre muffler do?
A centre muffler sits mid-system, between the front pipe and the rear muffler, and does part of the quietening work before the gas reaches the back of the car. On the VP-VS Commodore the STR105 is the 2.5in centre section, sized to ease flow through the middle of the system while keeping the note controlled.
Why the IRS-specific listing?
This part is listed for the Commodore sedan with independent rear suspension. IRS cars route the exhaust differently around the rear cradle than live-axle cars, so the centre section has to suit that layout. That's why this listing calls out IRS — fitting the right version matters for clearance.
Will it suit my VP or VS sedan?
It's listed to fit the VP and VS Commodore sedan with IRS. Confirm your car actually runs the IRS setup and send us the exact build, and we'll make sure the centre muffler matches before ordering.
What's involved in fitting at Oak Flats?
Oak Flats Muffler Men fits centre mufflers like the STR105 in-house across the Illawarra. We check the section clears the IRS cradle and the hangers sit right, then book the bay once it's confirmed for your sedan. On a car of this age we also inspect the joins front and rear of the centre section before fitting, so the new muffler seals to sound pipe rather than a rusted lip, and confirm the part against your build before it's ordered.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
