Parts for your 2012 Honda Accord-Exhaust mount

2012 Honda Accord exhaust mount (hanger/insulator)

Technical sources confirm the 2012 Honda Accord is fitted with exhaust mounts (also called hangers or rubber insulators). The Honda Accord 2008–2012 Factory Service Manual details removal and refit of the exhaust by unhooking the rubber hangers, Honda’s genuine parts catalogue lists multiple “rubber, exhaust mounting” insulators for the mid-pipe and rear muffler, and the Haynes Repair Manual covering Accord to 2012 describes checking and replacing the exhaust hangers during exhaust service. So yes—exhaust mounts are absolutely relevant on a 2012 Accord.

The exhaust mounts on a 2012 Accord suspend the exhaust system from the underbody, isolating vibration and allowing the pipes and muffler to move slightly as the engine rocks and the car hits bumps. That flexible support keeps the system quiet, prevents knocks against the body, and reduces stress on joints and flanges. Depending on model, there are typically three to five rubber mounts—fewer on the 4‑cylinder single-outlet cars, more on V6 or dual-outlet variants.

Over time, heat, road grime, and age harden or crack the rubber, letting the exhaust sag, tilt, or rattle. During routine servicing, it’s smart to include a quick check of each mount. Look for perished rubber, torn holes, or stretched hangers, and confirm the tailpipe sits even in the bumper cut-out. A torch helps spot splits around the hanger peg holes.

When replacement is due, it’s a straightforward job on stands: support the exhaust with a jack and wood block, spray silicone lube on the pegs, and lever the old insulator off. Dedicated exhaust-hanger pliers make it easier, but a sturdy flat-blade and patience do the trick. Refit new OEM-style rubber insulators (they balance isolation and durability better than overly hard polyurethane, which can transmit drone). Afterward, recheck clearances around heat shields, crossmembers and the rear bumper. If the system has recently been replaced or repaired, ensure any brackets are straight and fasteners correctly torqued—wonky brackets can chew through fresh mounts fast.

Signs it’s time for new mounts include:

• Rattles or thumps over bumps, especially from the rear
• Visible sagging or a crooked tailpipe
• Metal-on-metal tapping near heat shields
• Intermittent buzz/drone that changes with load or bumps

For most Aussie and Kiwi owners, a quick visual every service and replacement around the 8–12 year/120–200,000 km mark (earlier if coastal or high-heat use) keeps the Accord’s exhaust sitting sweet and rattle-free.

Popular questions

How many exhaust mounts does a 2012 Honda Accord have?
Most 4‑cylinder sedans have about three to four rubber mounts (mid-pipe and rear muffler). V6 or dual-outlet models usually have four to five. The exact count varies with body style and market spec, so checking the vehicle on a hoist or consulting the VIN-based parts catalogue is the safest bet.

What are the usual symptoms of a worn exhaust mount on a 2012 Accord?
Tell-tales include a sagging tailpipe, clonks over speed bumps, a tinny rattle near heat shields, and sometimes a drone that appears after hitting bumps. If the rubber is cracked or the hole has elongated, the exhaust can shift enough to tap the body or strain joints, so it’s worth fixing promptly.

Can a home mechanic replace the exhaust mounts?
Yes. On stands with the exhaust safely supported, the job is typically 30–60 minutes. Silicone spray and exhaust-hanger pliers make removal easier. Always let hot exhaust cool fully, wear gloves and eye protection, and double-check clearances after fitting new insulators.
