2010 Holden Commodore Exhaust Mount

Based on technical references including the Holden VE Commodore Service Manual (Exhaust System – Pipe/Muffler Support), GM Global Service Information, and the Holden Electronic Parts Catalogue (EPC) for VE models, the 2010 Holden Commodore is fitted with exhaust mounts (rubber insulators/hangers). These mounts are used at the mid-section and rear mufflers across sedan, Sportwagon, and ute variants. So yes—an exhaust mount is relevant on this vehicle.

The exhaust mount on a 2010 Commodore keeps the exhaust system securely suspended under the car while allowing a bit of flex as the engine moves and the pipework heats and cools. Those rubber insulators isolate vibration, prevent metal-on-metal contact, and help maintain correct tailpipe alignment. Without healthy mounts, the system can sag, knock on the underbody or suspension, and stress the flanges and welds.

As part of routine servicing, it’s smart to inspect the exhaust mounts every service interval (about 10,000–15,000 km). Look for cracks, splits, hardening, elongation of the holes, or mounts that have stretched to the point the exhaust sits off-centre. If there’s a rattle over bumps, a thump on start-up, or the tailpipe looks crooked, the mounts are likely due for replacement.

Replacement is straightforward but benefits from the right approach:

• Safely raise and support the vehicle, support the exhaust with a stand or jack.
• Use silicone spray to ease old mounts off, avoid petroleum-based lubes that degrade rubber.
• Check the bracketry and heat shields for cracks or loose fasteners, tighten to the workshop spec.
• Fit quality heat-resistant rubber insulators. Polyurethane options are stiffer and longer-lasting but can transmit more vibration into the cabin.
• After fitting, confirm tailpipe clearance around the bumper and suspension, and that there’s no contact under load.

For cars driven on rough roads, towed regularly, or fitted with aftermarket exhausts, plan on more frequent inspections. The mounts are inexpensive and can save bigger hassles by preventing stress fractures in pipes and mufflers. Following the Holden service procedures ensures the system sits correctly and stays quiet, which keeps the Commodore feeling tight and refined.

Popular questions about 2010 Holden Commodore exhaust mounts

How often should the exhaust mounts be replaced?
There’s no fixed kilometre limit, but they should be inspected at every service. Many last years, replace as soon as cracks, sagging, or vibration appear—especially if the vehicle tows or runs an aftermarket exhaust.

What are the common symptoms of a failing exhaust mount?
Rattles over bumps, clunks on start-up or shutdown, a droopy or off-centre tailpipe, and new exhaust drone or vibration in the cabin. Visible splits or stretched rubber are a giveaway.

Can polyurethane mounts be used instead of rubber?
Yes, they can add durability and firmer support, useful for performance setups. Just note they may pass a bit more vibration into the cabin compared with OEM-style rubber.
