Parts for your 2009 Honda Civic-Exhaust mount

2009 Honda Civic exhaust-mount: what it does and how to look after it

Yes, an exhaust-mount is absolutely used on the 2009 Honda Civic. Honda’s 2006–2011 Civic Factory Service Manual describes removal and refit of the exhaust “hanger rubber/insulator” pieces, and the Honda Electronic Parts Catalogue lists multiple exhaust insulators for this model by position (front, centre and rear). Independent references such as the Haynes Repair Manual for Honda Civic 2006–2011 also call for regular inspection of the exhaust rubber mountings. So, for any 2009 Honda Civic, the exhaust-mounts (often called hangers or insulators) are a normal, essential part of the system.

On the 2009 Civic, these rubber mounts suspend the exhaust from the underbody, keeping the pipe and muffler aligned while allowing movement as the engine rocks and the system heats and cools. They isolate vibration and stop the exhaust touching the body, subframe or bumper. That means fewer rattles, less drone, and far less chance of cracks at flanges or welds from stress.

With age and heat, the rubber can harden, crack, or stretch. A 2009 example is well into the age range where mounts may have perished. It’s smart to check them at regular servicing or WOF, and certainly any time there’s a new rattle, a thump over bumps, or the tailpipe looks off-centre.

• Tell-tales of a tired exhaust-mount: knocking on start-up or over speed humps, buzzing at idle, a droopy tailpipe, or visible splits/elongated holes in the rubber.
• When to replace: at the first sign of cracking or if the exhaust position can be shifted by hand more than expected. Consider doing adjacent mounts together.
• What to fit: OEM-style rubber insulators keep NVH civilised. Stiffer performance mounts exist, but can add cabin vibration.

Replacement is straightforward with the car safely supported. Let the exhaust cool, support it with a stand, spray silicone lube on the pegs, lever the old rubbers off, then slip the new ones on. While there, check brackets and bolts for corrosion, confirm heatshield clearances, and make sure the muffler sits central in the bumper cut-out with good clearance to the subframe. If any bracket bolts are removed, tighten to the factory spec listed in the service manual.

For most Civics, a quick look at every service and proactive replacement around the 10–15 year mark keeps the system quiet, properly aligned and compliant for Aussie and Kiwi roads.

Popular questions about 2009 Honda Civic exhaust-mounts

How many exhaust-mounts does a 2009 Civic have?
Most 2009 Civics use three to four rubber mounts depending on body style and market: typically one near the B‑pipe/centre, and two at the rear muffler. Some variants may add an extra support near the front pipe or resonator. A quick look under the rear bumper will usually reveal the pair holding the muffler can.

Can universal exhaust hangers be used on a 2009 Civic?
Universal rubber hangers can work if the hole spacing, thickness and durometer are suitable. However, OEM-spec insulators generally fit best and keep noise and vibration in check. If going universal, match the length closely so the tailpipe sits correctly and doesn’t contact the body.

What’s the risk of driving with a broken exhaust-mount?
If a mount fails, the exhaust can sag or swing, knocking on the subframe or bumper, stressing welds and flanges, or even damaging the oxygen sensor wiring. It’s usually an easy and affordable fix—best sorted before it takes out a gasket or cracks a pipe.
