Exhaust Systems Australia HOLDEN COMMODORE VP-VS 2 1/2" IRS CENTRE MUFFLER EVERFLO.
Category: Mufflers and resonators
An IRS-specific centre muffler, this Everflo 2in mid-system box from Exhaust Systems Australia is listed to fit the IRS Holden Commodore across VP to VS. The independent-rear routing is what sets it apart.
Commodores of this era came with either a live axle or independent rear suspension (IRS), and the IRS cars route their exhaust differently around the rear subframe and driveline. This Everflo centre muffler is listed for the IRS Commodore specifically, so its position and clearances suit that rear-end rather than the live-axle layout — getting the right one matters for fit.
As the mid-system box it carries the main quietening on the VP-VS Commodore, controlling drone and resonance through the middle of the car while the front and rear sections stay in place. At 2in it's the bore the supplier lists for this build — matched to a near-stock or moderate system rather than a big-bore one.
It's listed to fit the IRS Commodore across VP, VQ, VR and VS. The key check is whether your car is the IRS variant, since the live-axle cars use a different section. Confirm your rear-end type, exact series and existing 2in pipe size with the workshop before ordering.
Oak Flats Muffler Men fits centre mufflers like this in-house at our Illawarra workshop, aligning the 2in body around the IRS subframe to the factory hangers and welding or clamping it in. Exhaust Systems Australia lists it at $230; bring the Commodore in and we'll confirm the rear type and section first.
