Parts for your 2011 Subaru Outback-Exhaust mount

2011 Subaru Outback exhaust mount: what it does and when to replace it

Exhaust mounts absolutely are used on the 2011 Subaru Outback. Subaru’s Factory Service Manual for the 2010–2014 Outback/Legacy platform (Exhaust section, “Cushion Rubber”/hangers) specifies multiple rubber insulator mounts supporting the front pipe, centre section and rear mufflers. Subaru’s parts catalogue for the 2011 Outback (BR series) lists exhaust hanger/insulator components commonly referenced as cushion rubbers (e.g., insulator-hanger p/n 44022AE010/44022CA000 equivalents, plus associated brackets). So, an exhaust mount is not only relevant — it’s essential kit on this model.

On a 2011 Outback, the exhaust mounts (often called hangers or insulators) are the tough rubber cushions that hold the exhaust in place under the car. Their job is to isolate vibration, control movement over bumps, and keep the system correctly aligned so there’s no banging on the underbody or strain on flanges and flex joints. When these perishable bits harden, crack or stretch, owners may notice a thud over speed humps, a tinny rattle at idle, or the tailpipe sitting off-centre in the bumper cut-out.

They’re simple parts, but they work hard in heat, road grime and Kiwi/Oz weather, so regular inspection is smart. During routine servicing, a quick check of each mount for perishing, tearing, or excessive softness goes a long way. Any mount that’s cracked, oil-soaked, or allows the exhaust to move more than a couple of centimetres should be replaced as a set in that area to keep the system balanced.

• Service tip: a spritz of silicone spray helps slip new rubbers onto hangers without a wrestle.
• Good practice: inspect at each service or at least every 15,000–20,000 km, replace on condition rather than at a fixed interval.
• When replacing: support the exhaust with a stand or jack pad to avoid stressing joints.
• Quality matters: OE-spec rubber insulators resist heat and last longer than cheap generics.

If the Outback has seen beach runs, towing, or rural gravel, check the mounts more often — corrosion and extra heat cycles accelerate wear. A fresh set of exhaust mounts can quieten the cabin, protect oxygen sensors and catalytic converters from shock, and keep the tailpipe sitting neat as. It’s a small, affordable fix that prevents bigger dramas down the track.

Popular questions about 2011 Subaru Outback exhaust mounts

How can someone tell if an exhaust mount is failing on a 2011 Outback?
Common clues include a dull thud over bumps, a rattle at idle, or the muffler/tailpipe looking crooked. A quick under-car look often shows a cracked or stretched rubber insulator, or polished contact marks where the exhaust has been tapping the body or heat shield.

How long do the factory exhaust mounts typically last?
There’s no fixed lifespan — many last well over 100,000 km, but heat, road salt, oil contamination and off‑road use can shorten that. Treat them as “replace on condition” items and inspect at each service.

Can universal hangers be used instead of Subaru originals?
Universal rubbers can work in a pinch, provided the size, hole spacing and hardness (durometer) closely match OE spec. For best fit and durability, OE or quality aftermarket parts that match Subaru’s spec are the safer bet.
