Parts for your 2017 Honda Accord-Exhaust mount

2017 Honda Accord exhaust mounts: what they do and how to look after them

Based on technical sources, exhaust mounts are definitely fitted to the 2017 Honda Accord. The Honda Factory Service Manual for the 2013–2017 Accord (Exhaust System section) details removal and refit of the exhaust using the rubber mountings/hangers, and the Honda Electronic Parts Catalogue lists multiple exhaust rubber insulators and hanger brackets for this model. So an exhaust-mount (rubber hanger/insulator) is relevant and used on the 2017 Accord.

On the 2017 Accord, exhaust mounts are the tough rubber insulators that hold the exhaust in place from the mid‑pipe to the rear mufflers. They isolate vibration, keep the tailpipe aligned in the bumper cut-out, and allow a little flex so the system can move with engine torque and road bumps without knocking.

When these mounts age, the rubber can harden, crack, or stretch. That’s when owners start noticing tell‑tale signs: a metallic rattle over corrugations, a dull thud backing out of a driveway, or a tailpipe that sits off‑centre. In the cabin, there can be a buzz at idle because the exhaust isn’t isolated as well as it should be.

As part of regular servicing in Australia and New Zealand, it’s smart to inspect the exhaust mounts whenever the car’s on a hoist—say every 10,000–15,000 km service. Look for perished or split rubber, elongated holes, or a droopy muffler. A quick spray of silicone on the rubber helps keep them supple and makes future removal easier. If any mount is cracked or stretched, replace it in pairs on that section so the height stays even.

Replacement is straightforward for a competent DIYer, but a workshop can knock it over quickly. Support the exhaust with a stand or jack, spray the old mounts with silicone, then lever them off with exhaust-hanger pliers. Fit the new insulators the same way, check clearances around heat shields and the rear bumper, and make sure the tips are centred. If a bracket bolt was removed, snug it back to spec and recheck after a short drive.

Service life varies with climate and driving—lots of short trips, coastal air, or gravel roads can speed up ageing—so condition beats kilometres. Catching tired mounts early keeps the Accord quiet, prevents contact with underbody parts, and saves stress on joints and welds.

Popular questions about 2017 Honda Accord exhaust mounts

How often should the exhaust mounts be replaced?

There’s no fixed interval, they’re replaced on condition. Have them checked at each service. Many last well past 100,000 km, but cars in hotter, coastal, or rough-road use may need new mounts sooner.

What are the symptoms of a failing exhaust mount?

Listen and look for rattles over bumps, thuds when taking off, a drooping or off‑centre tailpipe, extra vibration at idle, or visibly cracked/perished rubber insulators.

Can a home mechanic change them?

Yes, with stands or ramps, eye protection, silicone spray, and ideally exhaust-hanger pliers. Work on a cool exhaust, support the system before unhooking mounts, and check alignment and clearances after refitting. If any bracketry is bent or rusty, let a workshop handle it.
