Parts for your 2000 Holden Commodore-Exhaust mount

2000 Holden Commodore exhaust mount

Yes, the 2000 Holden Commodore (VT Series II and early VX across V6 and V8, sedan/wagon/ute) uses exhaust mounts, also called exhaust hangers or insulators. This is documented in the Holden VT/VX Service Manual exhaust system section, which shows rubber insulators at the transmission crossmember, centre section and rear muffler, and reinforced by the Gregory’s Service and Repair Manual for VT–VX. Major parts catalogues from Mackay Consolidated and common local suppliers list direct-fit exhaust mounting rubbers for VT/VX, confirming fitment and locations.

The exhaust mounts on a 2000 Commodore do a simple but critical job: they hold the exhaust up, keep it centred, and stop vibrations travelling into the cabin. By suspending the pipes and mufflers on rubber, they maintain safe clearances to the body, drivetrain and suspension, reduce knocks over bumps, and prevent stress cracks in welds and flanges. Healthy mounts also help keep oxygen sensors and catalytic converters in the right place so the engine management can do its thing without false readings.

As part of regular servicing, it’s smart to eyeball the mounts whenever the car’s on a hoist. Look for perished or oil-soaked rubber, splits, elongation of the holes, and any signs the exhaust is sagging or touching a heat shield, crossmember, diff, or towbar. Common give-aways are a thump from the rear over speed humps, a new droning resonance at idle, or a tailpipe that suddenly sits off-centre in the bumper cut-out.

Replacement is straightforward with basic tools:

• Support the exhaust with a jack or stand before removing any hangers.
• Spray the hanger pegs with silicone spray or penetrant to slide the old rubbers off.
• Swap mounts in pairs on the same section (e.g., both rear muffler insulators) to keep things even.
• Refit brackets and fasteners to factory torque per the Holden manual, don’t overtighten into captive nuts.
• Recheck clearances around the propshaft, fuel tank, spare wheel well and rear suspension, and make sure heat shields sit properly.

For daily drivers, OE-style rubber gives the best comfort and NVH. If the car is lowered or runs a heavier aftermarket system, a quality polyurethane insulator can limit movement, but expect a touch more vibration. On sedans and wagons you’ll typically find mounts at the transmission crossmember, mid-pipe and rear muffler, utes often have an additional tail-end hanger. Inspect every service or 10,000 km—mounts can last years, but heat, oil leaks and coastal conditions in AU/NZ will age them faster. Given the low cost, replacing tired mounts is cheap insurance against cracked welds, rattles and an exhaust that sits wonky.

Popular questions about 2000 Holden Commodore exhaust mounts

How often should the exhaust mounts be replaced?
There’s no fixed interval. Check them at each service. Many last 5–10 years, but heat cycles, oil contamination and coastal air can shorten that. Replace at the first signs of cracking, sagging or contact with the body.

What are the symptoms of a bad exhaust mount on a VT/VX?
Listen for a knock over bumps, a new drone at idle or cruise, or notice the tailpipe sitting off-centre. Underneath, look for split or stretched rubbers and shiny rub marks where the exhaust has been touching.

Rubber or polyurethane hangers—what’s best?
Rubber is closest to factory feel and usually the quietest. Polyurethane is stiffer, great for lowered cars or heavier aftermarket systems because it controls movement better, but it can add a bit of vibration. Choose based on how the car’s used.
