Parts for your 2011 Honda Accord-Exhaust mount

2011 Honda Accord exhaust mounts — what they do and how to look after them

Exhaust mounts are absolutely used on the 2011 Honda Accord. Technical sources including the Honda Factory Service Manual for the 2008–2012 Accord (exhaust system section) and Honda’s genuine parts catalogues list multiple rubber exhaust insulators/hangers along the exhaust. Major aftermarket catalogues for the 2011 Accord also specify replacement exhaust insulators. So, an exhaust-mount is relevant to this model and forms a normal service item when worn.

On the Accord, the exhaust mounts are the rubber insulators that suspend the exhaust system from the underbody. They isolate vibration, keep the muffler and pipes correctly positioned, and allow a bit of movement as the engine rocks and the system heats and cools. Without healthy mounts, the exhaust can sit crooked, knock on the body, rattle at idle, or stress the welds and flanges.

It’s smart to have the mounts checked at each service or at least every 10,000–15,000 kilometres, especially on cars that see lots of city stop–start or rough roads. A tech will look for perished or cracked rubber, stretched holes, torn insulators, or bent metal hangers. If the tailpipe looks low, the muffler is skewed, or there’s a buzz that changes with engine speed, the mounts are prime suspects.

• Common signs: thumps over bumps, metallic rattles at idle, sagging tailpipe, increased cabin vibration, or fresh scuff marks where the exhaust has touched heat shields or the subframe.

Replacement is straightforward with the car safely supported. The exhaust is lightly supported with a stand, the old rubbers are eased off (a shot of silicone spray helps), and new high-temp insulators are fitted. It’s best to replace mounts in pairs or as a set, and to choose OEM or quality equivalents that match the Accord’s bracket sizes. After fitting, the exhaust alignment is checked so there’s clearance to shields, suspension arms, and the bumper, and all joints are inspected for strain.

• Service tips: use a non-petroleum rubber lubricant, avoid levering against oxygen sensors, and recheck clearances after a heat cycle. If a metal hanger is bent, straighten or replace it so the new rubbers aren’t overloaded.

There are typically several mounts along the Accord’s system (exact count varies with engine and body style). They’re inexpensive parts that save bigger hassles by preventing stress cracks, leaks, and annoying noises.

FAQs — 2011 Honda Accord exhaust mount

How many exhaust mounts does a 2011 Honda Accord have?
Most 2011 Accords have several rubber insulators from the mid-pipe back to the rear muffler, with the exact number depending on engine (2.4L or 3.5L) and body style. A quick visual under the car or a look at the parts diagram will confirm the count on a specific vehicle.

What are the signs the exhaust mounts need replacing?
Look for a drooping tailpipe, knocking over bumps, buzzing at idle, or new marks where the exhaust has tapped a shield. Perished, cracked, or stretched rubbers are the usual giveaway and are easy to spot on a hoist.

Is it OK to drive with a broken exhaust mount?
It’ll often still drive, but it’s not ideal. A broken mount can let the system shift and hit the body, strain joints, or damage sensors. It’s best to drive gently and get it sorted promptly to avoid bigger repair bills.
