2019 Honda Accord exhaust mount: what it is, what it does, and when to replace it

Yes, the 2019 Honda Accord uses exhaust mounts (also called exhaust hangers or insulators). Technical sources that confirm this include: the Honda Service Manual (2018–2020 Accord) Exhaust System section, which specifies removing and refitting the exhaust hanger rubbers during exhaust work, and the Honda Electronic Parts Catalogue for the 2019 Accord, which lists multiple rubber exhaust insulators supporting the front pipe, mid-pipe and rear muffler assemblies. These components are standard on modern Accords to suspend the exhaust under the body, isolate vibration, and keep clearances correct.

On a 2019 Accord, the exhaust mounts are small but important rubber insulators that hold the exhaust system in place while soaking up vibration so there’s less noise and harshness in the cabin. They also keep the pipework aligned so it doesn’t knock on heat shields, the subframe, or the rear bumper. When an exhaust mount perishes, stretches, or tears, the system can sag or shift, which can cause rattles over bumps, thumps on start-up or shutdown, or even stress cracks and leaks at flanges and welds.

Servicing advice is pretty straightforward. During routine services or whenever the vehicle is on a hoist, it’s smart to visually check each rubber mount for cracks, glazing/hardening, elongation of the holes, or oil contamination. A quick pry with a trim tool can reveal excessive softness. Any mount that’s cracked or overly squishy should be replaced as a set at that section to keep the exhaust sitting square. There’s no fixed kilometre interval—replacement is condition-based—but coastal cars, high-heat driving, and older rubbers tend to wear faster.

Replacement is usually a simple job: support the exhaust with a stand, spray a little silicone lubricant on the pegs, and slide the old insulators off. Dedicated exhaust-hanger pliers help, but a sturdy hook tool works too. Fit OEM-equivalent rubber insulators for factory NVH, or choose stiffer polyurethane if the driver wants a sportier, more controlled feel (noting there may be a touch more vibration). After any mount work, check exhaust clearances around heat shields, suspension arms and the rear bumper, and ensure all clamps and fasteners are tightened to factory spec. Keeping those humble mounts healthy will protect the rest of the system and keep the Accord feeling quiet and refined.

• Common signs it’s time: rear muffler looks low or crooked, new rattles on cold start, knocks over speed humps, or visible cracks in the rubber.
• Pro tip: if a mount failed due to oil soak, find and fix the fluid leak as well or the new rubber won’t last.

Popular questions about 2019 Honda Accord exhaust mounts

How often should exhaust mounts be replaced on a 2019 Accord?
There’s no set interval, they’re replaced on condition. Many last well beyond 100,000 km, but heat, road grime, and oil contamination can age them sooner. Inspect them at every service when the car’s on a hoist and replace any that are cracked, stretched, or hardened.

What are the symptoms of a bad exhaust mount?
Look for a sagging rear muffler, new rattles at idle or on start-up, clunks over bumps, or the tailpipe hitting the bumper cut-out. You might also hear metallic tapping on acceleration if the pipe touches a heat shield.

Should they choose OEM rubber or aftermarket polyurethane mounts?
OEM-style rubber keeps factory comfort and is ideal for daily driving. Polyurethane mounts are tougher and hold alignment well, handy for performance exhausts, but can add a hint more vibration and noise. For most 2019 Accord owners, quality OEM-equivalent rubbers are the sweet spot.
