2005 Honda Accord Exhaust Mounts — Purpose, Care, and Replacement

Exhaust mounts are absolutely fitted to the 2005 Honda Accord. Technical references that confirm this include the Honda Accord 2003–2007 Service Manual (Exhaust System section), which details the exhaust pipe and muffler supported by rubber insulators/hangers, the Honda Genuine Parts catalogues that list muffler/exhaust pipe mounting rubbers for the 2005 Accord, and aftermarket catalogues (e.g., Walker/Bosal) that supply replacement exhaust insulators for this model. So yes—exhaust mounts are relevant and used on this vehicle.

On the Accord, the exhaust mounts (often called hangers or insulators) are small but crucial. They suspend the exhaust under the car, isolating vibration and road shock so the cabin stays quiet and the system doesn’t rattle. By controlling movement, the mounts protect the flex joint, catalytic converter, and oxygen sensor wiring, and they help keep the tailpipe centred in the bumper cut-out.

While there’s no fixed replacement interval, the mounts live a hard life—heat, road grime, and age harden the rubber. It’s smart to check them during regular servicing (every 10,000–15,000 km or annually). If the rubber is cracked, perished, or stretched, swap them out. Many owners see 5–10 years from a set depending on climate and driving.

• Typical symptoms of tired mounts:
  • Knocking or thumping from under the car over bumps or at start-up.
  • Tailpipe sitting low or off-centre in the bumper.
  • Buzzing/vibration at idle that changes with engine speed.
  • Fresh shiny rub marks on the exhaust or body from contact.

Replacement is straightforward with the right approach. Always let the exhaust cool. Support the system with a jack stand before removing any mount. A quick spray of silicone lube helps the old rubber slip off. Replace any rusted brackets or hardware at the same time, and consider doing mounts in pairs so the system sits evenly. After fitting, check the clearances around the subframe, heat shields, and bumper, and make sure the tailpipe sits neatly.

Ignoring a failed mount can stress the flex pipe, rattle heat shields loose, or melt nearby components if the system sags. It’s a cheap, quick fix that keeps the Accord feeling tight and quiet on Aussie and Kiwi roads.

Popular questions about 2005 Honda Accord exhaust mounts

How many exhaust mounts does a 2005 Accord have?
Most 2005 Accords use several mounts—typically one near the front pipe, one around the centre, and one or two at the rear muffler. Exact count varies with engine (4-cyl vs V6) and body style, but three to five is common.

Can they drive with a broken exhaust mount?
They could, but it’s not ideal. A broken mount lets the system swing, which can crack the flex joint, strain O2 sensor wiring, or cause banging on the floor. It may also lead to exhaust leaks and extra noise. Best to sort it promptly.

What’s the best way to make replacement easier?
Use silicone spray or rubber-safe lubricant on the hangers, support the exhaust with a stand, and refit one mount at a time to keep alignment. If the rubber is rock-hard or torn, replace rather than trying to salvage it.
