2001 Honda Odyssey exhaust-mount (hanger): purpose, fitment and service tips

Per Honda’s Factory Service Manual for the 1999–2004 Odyssey (Helm) and the Honda Electronic Parts Catalogue, the 2001 Honda Odyssey uses multiple exhaust mounts (also called exhaust hangers or insulators). These rubber mounts support the mid‑pipe, resonator and rear muffler, making “exhaust‑mount” absolutely relevant for this model.

On this Odyssey, the exhaust mounts do the heavy lifting quietly. They suspend the exhaust while isolating vibration from the cabin, keep the muffler and tailpipe aligned in the bumper cut‑out, and allow for thermal expansion and engine movement without stressing the pipes. Good mounts prevent droning, knocks over bumps, and premature gasket or flange failures.

There’s no fixed replacement interval, but they’re wear items. Heat cycles, age and road grime harden or crack the rubber. In coastal Aussie and Kiwi conditions, salt exposure can also corrode the brackets the mounts slip over, accelerating issues. At regular services (every 10,000–15,000 km), a quick visual check pays off: look for perished rubber, splits, elongation of the holes, or a tailpipe that’s sitting lower or off‑centre.

Common clues the Odyssey’s mounts are due:

• Rattles or knocking from the rear over bumps or at start‑up
• Tailpipe touching the bumper or swinging more than usual
• Exhaust banging subframes or heat shields, or new exhaust leaks after a bump

Replacement is straightforward with the vehicle safely supported and the exhaust cool. Support the exhaust with a jack stand, wet the rubber with silicone spray or soapy water, and lever the old mount off the pegs. Inspect the steel hangers and heat shields, clean light rust and replace any bent brackets. Fit quality OEM‑style rubber (ideal for NVH on a family van). Polyurethane lasts longer but can transmit a touch more vibration—your call. Once refitted, confirm 10–20 mm clearance from the body and no contact at full droop or when rocking the system by hand. If mounts keep failing, check engine and transmission mounts, excessive drivetrain movement can punish the exhaust.

Budget a few minutes per hanger—often 15–30 minutes each—and consider replacing them as a set where practical so the system sits square and quiet for the long haul.

How many exhaust mounts does a 2001 Honda Odyssey have?

Most Australian and New Zealand‑delivered 2001 Odysseys run three to four rubber mounts from the mid‑pipe to the rear muffler. Exact count can vary with exhaust design and any aftermarket sections. A quick look on a hoist will confirm what’s fitted to the van in front of you.

Is it safe to drive with a broken exhaust mount?

Short, gentle trips may be possible, but it’s not ideal. A sagging exhaust can hit the body or road, stress flanges and gaskets, and even melt the bumper if the tailpipe shifts. It’s best to support or repair it promptly to avoid collateral damage.

Rubber vs polyurethane mounts on an Odyssey—what’s better?

OEM‑style rubber offers the best comfort and noise isolation, which suits family‑duty Odysseys. Polyurethane can last longer and resist heat and oil better, but may pass a bit more vibration into the cabin. If quiet cruising is the priority, stick with quality rubber, if longevity under tougher use is key, polyurethane is a fair choice.
