Parts for your 2016 Honda Odyssey-Exhaust mount

2016 Honda Odyssey exhaust-mount: what it does and when to replace it

Exhaust mounts are very much used—and essential—on the 2016 Honda Odyssey. Factory guidance in the Honda workshop manual for the 2011–2017 Odyssey (Exhaust System procedures) calls out removing and refitting the exhaust from rubber hanger insulators, and Honda parts catalogues list multiple “exhaust insulator/mount” pieces for the rear muffler and centre pipe on this model. Aftermarket catalogues for the same vehicle also supply direct-fit rubber hangers, confirming the part is standard equipment.

On this Odyssey, the exhaust mounts (also called hangers or insulators) are heat‑resistant rubber blocks that suspend the exhaust from the body. Their job is to isolate vibration, keep the pipe and muffler aligned, and stop the system thumping the floor or rear bumper. Typically there are four to five mounts across the mid‑pipe and rear muffler, each one sliding over a steel peg.

They cop a tough life—heat cycles, road grime, and the odd splash of oil—so the rubber can harden, crack, or tear. When that happens, the exhaust can sag, rattle over bumps, or buzz at certain revs. Left too long, a failed mount can stress welds, flex joints, or O₂ sensor wiring.

Good servicing practice is to inspect the mounts whenever the Odyssey is on a hoist—ideal at regular services or any time the exhaust is off. Look for perished rubber, splits, elongation of the holes, or heat glazing. If one is gone, the rest often aren’t far behind, so replacing mounts in pairs or as a small set is smart. Genuine or OE‑equivalent rubber is best for the right durometer and fit.

• Typical symptoms it’s time to swap them:
  • Clunking or drumming from the rear over bumps
  • Exhaust tip sitting off‑centre or touching the bumper
  • Extra cabin vibration at idle
  • Visible cracks or a mount that’s stretched thin

Replacement is straightforward: support the exhaust, spray silicone lube on the pegs, and lever the old mounts off. Dedicated exhaust‑hanger pliers help, but a pry bar works with care. Fit the new mounts in the same orientation, check clearances around the subframe, heat shields, and bumper, then road‑test for any rattles. Always work on a cool exhaust and use stands or a hoist—no wriggling under a car on a jack.

There’s no set interval, most last many years, but by 8–10 years it’s common to see wear. Parts are inexpensive, and the labour is usually quick unless hardware is rusty.

Popular questions about 2016 Honda Odyssey exhaust mounts

How many exhaust mounts does a 2016 Odyssey have?
Most have four to five rubber mounts: usually two at the rear muffler and two to three along the centre/front pipe. Exact count can vary slightly by market spec and exhaust layout, but that’s the typical setup.

Is it safe to drive with a broken exhaust mount?
It might get you home, but it’s not ideal. A sagging system can knock the body, strain the flex joint, or stress O₂ sensor wires. If a second mount lets go, the exhaust can drop further and cause damage. Best to sort it promptly.

What does replacement usually cost?
The mounts themselves are budget‑friendly—often A$15–A$40 each—while labour is commonly 0.5–1.0 hour for one or two mounts, more if corrosion fights back. DIYers with ramps and basic tools can usually handle the job.
