The detail that sets the Redback STR105 apart is the rear end it is cut for: it is a centre muffler listed to fit the Holden Commodore sedan VP–VS with independent rear suspension. The IRS sub-floor changes how the centre section routes, and this box is matched to it.
Why does IRS matter for the centre muffler?
On the VP–VS Commodore, cars fitted with independent rear suspension carry a different rear cradle and floorpan layout than the live-axle versions. That alters the clearances the exhaust has to thread through under the floor. The STR105 is the centre muffler matched to the IRS-equipped sedan, so it sits where that body expects it rather than fouling the cradle.
What does a centre muffler change?
The centre (mid) muffler is the first silencer along the underfloor run and takes the early pass at quietening the system before the rear box. It is a common rust-out point where road spray sits, and a tired one shows up as a drone or blow ahead of the tailpipe. This is a like-for-like mid silencer rather than a tone change.
Will it suit my VP–VS Commodore sedan?
It is listed to fit the Holden Commodore sedan VP to VS with IRS. Because the IRS and live-axle cars route differently, confirm your exact build and rear-end type with the workshop before ordering — that is the detail that decides whether this box or another fits your car.
What does fitting involve in the Illawarra?
Oak Flats Muffler Men fits centre mufflers like the STR105 in-house across the Illawarra. We confirm the rear-suspension type on your car, check the feed and exit pipes and the hangers, and make sure the box clears the IRS cradle 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 STR105 only for IRS Commodores?
- It is listed for the Holden Commodore sedan VP–VS with independent rear suspension. Live-axle cars can route differently, so confirm your rear-end type with the workshop first.
- Is this a centre or rear muffler?
- It is the centre (mid-section) muffler, working along the underfloor run ahead of the rear silencer.
