2018 Honda Accord exhaust-mount — what it does and how to look after it
Based on technical sources, an exhaust-mount is absolutely relevant and used on the 2018 Honda Accord. Honda’s service information for the model year details the exhaust system being suspended on rubber insulators/mounts to isolate vibration and support the pipe and muffler assemblies. Honda’s genuine parts catalogues for the 2018 Accord list “Exhaust Insulator/Mount” items, and common aftermarket catalogues (e.g., Walker and Dorman) offer direct-fit exhaust hanger insulators for this vehicle. That means the 2018 Accord relies on multiple rubber exhaust mounts to keep the system aligned, quiet and safely supported.
On this Accord, the exhaust-mounts (also called hangers or insulators) are simple rubber bushings that hold the exhaust to brackets on the underbody. Their job is to absorb movement so engine pulses and road bumps don’t transmit harshness into the cabin, and to keep the muffler and pipes from knocking the bodywork.
Because they’re rubber, they age. Heat cycles, road grime and a bit of oil mist can harden or crack them over time. When they get tired, the exhaust can sag, rattle over bumps, or thump on start-up and shutdown. Replacing the mounts restores correct height and alignment, which also protects gaskets and joints from excess stress.
- Tell-tale signs they’re due: droopy tailpipe, clunks from the rear, visible cracking or tearing in the rubber, or metal-to-metal contact marks near the exhaust path.
- Inspection rhythm: check at every service or at least every 20,000–30,000 km, especially if the car sees short trips or coastal conditions.
Replacement is straightforward and a good DIY for a confident home mechanic, but always work on a cool exhaust and support the system before removing anything. A spritz of silicone spray helps the old rubber slip off. Fit new mounts in the same positions and ensure the exhaust sits centred in the bumper cut-out with adequate clearance all round. Any bracket fasteners removed should be tightened to the factory torque listed in Honda service information.
- Safely raise and support the car, support the exhaust with a jack and wood block.
- Lubricate and remove old mounts, inspect brackets for rust or cracks.
- Install quality OEM-equivalent mounts, confirm clearances and road-test for noise.
Quality counts here: genuine or reputable aftermarket insulators last longer and keep the Accord feeling tight and quiet on Aussie and Kiwi roads.
Popular questions
How many exhaust-mounts does a 2018 Honda Accord have?
Most 2018 Accord sedans use several mounts—typically one forward on the system and multiple around the rear muffler area. Exact count varies with engine (1.5T, 2.0T, or Hybrid) and trim, but expect around three to five rubber insulators.
Can the exhaust-mounts be replaced at home?
Yes, with basic tools, axle stands, and patience. Let the exhaust cool, support it before removing any mounts, and use silicone spray to ease the rubber off the pegs. If any metal brackets are bent or corroded, address those before refitting.
How long do the mounts last?
There’s no fixed interval. Many last well past 100,000 km, but heat and climate speed up ageing. Inspect at each service and replace when cracked, hardened, or if there’s any rattle or sag.
