Parts for your 1999 Honda Accord-Exhaust mount

1999 Honda Accord exhaust-mount — what it does and when to replace it

Yes, the 1999 Honda Accord uses exhaust mounts. Honda’s Factory Service Manual for the 1998–2002 Accord (Exhaust System, Removal/Installation) and the Honda Electronic Parts Catalogue for the CG/CF/CL series both specify rubber exhaust hanger insulators and their brackets supporting the centre pipe, resonator and rear muffler. Aftermarket catalogues and OE parts listings likewise show multiple rubber hangers for this model, confirming the part is fitted and serviceable.

On a ’99 Accord, the exhaust-mounts (rubber hangers/insulators) hold the exhaust in place while letting it move a touch as the engine twists and the car hits bumps. That soft isolation keeps the system from knocking on the body, protects the manifold and catalytic converter from stress, and helps keep cabin noise down. Typically there are three to five mounts from the front pipe back to the muffler, depending on body style and exact trim.

As part of regular servicing, it’s smart to eyeball the mounts every 10,000–15,000 km or at each oil change. Rubber perishes with heat and age, especially around the rear muffler. When the hangers crack or stretch, the tailpipe can droop or shift, leading to rattles over bumps or the exhaust tapping the subframe or bumper. Replacing tired mounts early prevents leaks at joints and saves brackets from snapping.

• Tell-tales it’s time: thumps or rattles from the rear, a sagging tailpipe, droning that changes with load, or visibly cracked/glazed rubber.
• Replacement tips: let the exhaust cool, support it with a stand, spritz penetrant/silicone on the old rubbers, and lever them off with hanger pliers. Fit new OE-spec insulators, then check clearances around the bumper, suspension and heat shields.
• Good practice: replace mounts in pairs/groups near the same section, inspect the steel brackets and studs for rust, and snug fasteners to the service manual torque specs. Lowered cars or those that tow may benefit from slightly stiffer hangers to keep clearances.

Most owners will be fine sticking with OEM-style rubber for comfort. Polyurethane options last longer and control movement better, but can add a touch of vibration. Either way, fresh mounts make an immediate difference to refinement and keep the Accord’s exhaust sitting exactly where Honda intended.

Popular questions about 1999 Honda Accord exhaust-mounts

How many exhaust mounts does a 1999 Accord have, and where are they?
The typical setup uses three to five rubber hangers: one supporting the front/centre section, one or two around the resonator area, and one or two at the rear muffler. Exact count can vary slightly by body style and engine, but the rear muffler always has dedicated mounts to control weight and movement.

What symptoms mean the mounts need replacing?
Common signs include a drooping tailpipe, clunks over speed bumps, a rattle at idle that quietens when the exhaust is pushed by hand, or visible cracking of the rubber. If the exhaust starts touching heat shields or the bumper, you may also hear a low-frequency drone in the cabin.

Should they choose OEM rubber or upgraded polyurethane?
OEM rubber keeps factory comfort and is ideal for daily driving. Polyurethane hangers are tougher and restrict movement better, useful on lowered cars or where extra load is carried, but can pass a bit more vibration into the cabin. Pick based on how the Accord is used and the desired refinement.
