Parts for your 2007 Holden Commodore-Exhaust mount

2007 Holden Commodore exhaust mount

Yes, the 2007 Holden Commodore runs exhaust mounts (also called exhaust hangers/insulators). Technical references including the Holden VE Commodore Service Manual (Exhaust System section, MY06–MY13) and the GM Holden Electronic Parts Catalogue for VE series list multiple rubber exhaust insulators that support the front pipe, centre section, and rear mufflers. Aftermarket fitting guides from major suppliers likewise specify OE-style rubber hangers for VE models. So the exhaust mount is very much a fitted and serviceable item on this vehicle.

The exhaust mount’s job is to suspend the exhaust under the car while isolating vibration and engine movement. Those rubber insulators keep the pipes and mufflers sitting at the right height and clear of the body, heat shields, driveshaft, and rear suspension. Good mounts prevent knocks over bumps, stop the tailpipe from drooping, and protect flex joints, welds, and oxygen sensor wiring from stress.

On a VE Commodore (including 2007 Omega, SV6, SS and variants), you’ll typically find mounts at the rear muffler(s) and at the centre section. Over time, heat and road grime harden or crack the rubber. Common signs they’re due are a thump from the rear over bumps, buzzing at idle, visible sag at the tip, or perished/tearing rubber.

Inspection is straightforward: with the car safely on stands and the exhaust cool, check each insulator for splits, elongation, or separated bonding. As part of regular servicing, it’s smart to inspect them every 15,000 km and expect replacement somewhere in the 5–10 year range depending on heat cycles and conditions.

Replacement is a simple driveway job with basic tools:

• Support the exhaust with a jack or strap.
• Spray silicone lube on the hanger pins.
• Lever the old rubber off, fit the new insulator, and ensure the exhaust sits central with adequate clearance.

If brackets are removed, tighten fasteners to the workshop manual specs and recheck alignment after a short drive. OE-style rubber insulators keep factory NVH levels, polyurethane can firm things up but may transmit more vibration. If one mount has failed, replacing the pair on that section helps keep the system even. Also give the nearby heat shields a rattle-check and make sure engine and transmission mounts are healthy—excess drivetrain movement can shorten exhaust mount life.

Popular questions about 2007 Holden Commodore exhaust mounts

How do you know an exhaust mount has failed on a 2007 Commodore?
Listen for a knock or rattle over bumps, a buzz at idle, or look for a drooping tailpipe. A quick visual check usually shows the culprit: cracked rubber, elongated holes, or a mount that’s torn clean through.

Are polyurethane exhaust mounts a good upgrade?
They can be if you want a slightly firmer, more durable option—handy on cars with heavier aftermarket systems. Just note they can transmit a touch more vibration into the cabin compared with soft OE rubber.

Is it safe to drive with a broken exhaust mount?
It’s not ideal. The exhaust can shift, hit the body or suspension, stress welds, or damage sensors. Short, careful trips might be doable, but it’s best to sort it promptly to avoid bigger repairs.
