Parts for your 2014 Honda Civic-Exhaust mount

2014 Honda Civic exhaust mount — what it does and when to replace it

The 2014 Honda Civic is fitted with exhaust mounts (also called exhaust hangers/insulators). This is confirmed in the Honda Civic 2012–2015 Service Manual (Exhaust System section) and Honda’s Electronic Parts Catalogue for the FB/FG chassis, which list rubber “exhaust insulators” supporting the centre pipe and rear muffler. So yes, an exhaust mount is absolutely relevant to this model.

On this Civic, the exhaust mounts are tough rubber blocks that hold the exhaust system to the body while letting it move a touch. Their job is to carry the weight of the pipes and muffler, absorb vibration so the cabin stays quiet, and keep everything aligned so the tailpipe sits neatly in the bumper cut-out. They also allow a bit of flex as the exhaust heats and cools, which helps prevent cracks and broken welds.

Over time the rubber can harden, crack, or stretch. If one lets go or sags too much, the exhaust can knock on the subframe or heat shields, drone more on the motorway, or sit crooked at the rear. In NZ WOF and Aussie rego inspections, the exhaust has to be secure, so tired mounts can be a fail point.

• Common signs it’s time to replace: dull knocks over bumps, a saggy or off-centre tailpipe, new rattles at idle, or visible perishing/cracks in the rubber.
• Typical inspection interval: give them a look at each service (10–15,000 km) and after any curbing or road strike.

Replacement is straightforward for a workshop or handy DIYer. Let the exhaust cool, support it with a jack or stand, and spritz the old mounts with silicone spray to slide them off the pegs. Fit like-for-like quality rubber insulators, if the Civic runs a heavier aftermarket system, consider higher-durometer (stiffer) mounts to keep it controlled. It’s smart to replace mounts in pairs or as a set so the system sits level. While there, check the hanger pegs for rust, heat shield clearances, and torque on any bracket bolts. Avoid oil contamination on the new rubbers, and recheck alignment after a short drive.

Kept in good nick, exhaust mounts can last years, but climate, kilometres, and driving conditions make a big difference. A quick check during regular servicing helps the Civic stay rattle-free and compliant.

Popular questions about 2014 Honda Civic exhaust mounts

How long do exhaust mounts typically last on a 2014 Civic?
There’s no fixed interval, but many last 5–10 years. Heat, road grime, and short trips can shorten life. Inspect at each service and replace when cracked, softened, or stretched rather than waiting for a rattle.

Can polyurethane exhaust mounts be used on this model?
Yes. Polyurethane hangers can control heavier aftermarket exhausts better and reduce sag. They may pass a bit more vibration into the cabin, so choose a sensible hardness (around 60–70A) for road use.

Why does the tailpipe sit crooked after a bump?
Often a stretched or torn mount lets the muffler droop or twist. Check all hanger rubbers and the metal pegs. Replacing the affected mounts and realigning the system usually brings the tailpipe back to centre.
