This Everflo rear muffler (HOLDEN-COMMODORE-VB-VS-2-1-2-VS-V8-ONLY-REAR-MUFFLER-EVERFLO-EXCEPT-IRS) is the tail box for the Holden Commodore VB–VS V8, on a 2in bore — for the V8 only, and not the IRS cars. As the rear muffler it sets the final note at the tailpipe.

What does a rear muffler do here?

The rear muffler is the last silencer in the system, so it has the most say in the note that leaves the tailpipe. On a 2in bore this Everflo suits the VB–VS V8 in standard or lightly worked form. Swapping just the rear box lets you reset the tailpipe character without disturbing the centre of the system — the targeted change when it's the back of the car you want to work on.

Why V8-only and except-IRS?

It's listed for the V8 only, and specifically not the IRS (independent rear suspension) cars — the IRS rear end packages the muffler and pipe differently, so it runs its own box. That fitment note matters: the live-axle V8 cars take this muffler, the IRS cars don't. There's no dB data published, so the honest way to judge the note is to hear a comparable fit.

Will it suit my VB–VS V8?

It's listed to fit the Holden Commodore VB–VS V8, except IRS. Confirm whether your car runs the live axle or IRS, and check your exact build with the workshop before ordering so you get the right rear box.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits rear mufflers like this in-house across the Illawarra. Exhaust Systems Australia supplies the box; we match it to the VB–VS rear hangers, check clearance over the axle and to the floor, and join it square so it sits without strain. Bring the car in and we'll confirm fitment and book the bay.

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

Common questions
