Parts for your 2006 Holden Commodore-Exhaust mount

2006 Holden Commodore Exhaust Mounts

Yes, the 2006 Holden Commodore does use exhaust mounts (also called hangers or insulators). This is documented in Holden’s VZ and VE Commodore Workshop Manuals under Exhaust System, and in GM Global Service Information (GSI) for the VE platform, which show multiple rubber insulators and brackets supporting the system from the catalytic converters through to the rear mufflers. So the exhaust-mount is absolutely relevant to any 2006 Commodore—whether it’s a late VZ or the first of the VE range.

On this Commodore, the exhaust mounts suspend the pipework and mufflers from the body, isolating vibration and keeping the hot exhaust away from the floor, fuel lines, and rear cradle. They allow controlled movement as the engine and driveline shift under load, preventing stress cracks and keeping the tips sitting nicely in the bumper cut-outs.

• Typical locations include: near the transmission crossmember, around the centre muffler/resonator, and over the rear cradle to each tailpipe or rear muffler. Placement varies slightly between sedan, wagon and ute, and between VZ and VE layouts.

Common signs the mounts are due include a metallic knock over bumps, droning at idle, sagging or off‑centre tailpipes, and visible cracking or splitting of the rubber. If the exhaust can be pushed to touch a heat shield or floorpan, the mounts are tired.

Servicing tips: give the mounts a quick inspection at each service interval, or at least every 20,000 km. Look for perished, oil‑soaked or torn rubber, elongated holes, and bent or rusty brackets. When one fails, it’s smart to replace them in pairs or as a set to keep heights even.

Replacement is straightforward with the right approach. Let the exhaust cool fully. Support the system with a stand or jack and a block of wood. A spritz of silicone spray and an exhaust-hanger tool (or stout pliers) makes removal far easier. Swap one insulator at a time so the system stays aligned. Refit brackets and tighten to the factory specs as per the Holden manual, then check clearances around heat shields, the spare-wheel well, and any towbar or diffuser.

For parts, quality OEM-style rubber insulators work well on stock systems. Polyurethane or “heavy‑duty” options can help on cars with big tow loads or aftermarket exhausts, but may pass a touch more vibration into the cabin. Coastal driving and gravel roads in Aus and NZ can age rubber faster—another reason to have them checked during regular servicing. A loose or poorly supported exhaust can also affect roadworthy/WOF outcomes.

Popular questions

How often should exhaust mounts be replaced on a 2006 Commodore?

There’s no fixed kilometre limit—inspect every service and replace when you see cracking, sagging or if the exhaust knocks. Many last well past 100,000 km, but cars with towing, lowered suspension or aftermarket systems may need them sooner.

Is it safe to drive with a broken exhaust mount?

Not ideal. The exhaust can drop, stress joints, or contact the body and melt nearby components. If one mount fails, drive gently to a workshop and avoid rough roads. Multiple failed mounts warrant a tow to prevent further damage.

Are VZ and VE exhaust mounts the same in 2006?

They can differ by platform and body style. Early 2006 VZ and late 2006 VE use different bracket layouts and insulator shapes in places. Match parts using VIN, body type (sedan/wagon/ute) and exhaust configuration to get the correct mounts.
