Parts for your 2011 Subaru Exiga-Exhaust mount

2011 Subaru Exiga exhaust mounts — what they do and when to replace them

Yes, the 2011 Subaru Exiga uses exhaust mounts. Technical references including the Subaru factory service manual for the YA-series Exiga (exhaust system section) and the genuine Subaru parts catalogue (Group 44 – Exhaust, listing the exhaust insulator/hanger) specify multiple rubber exhaust mounts supporting the front pipe, centre section, and rear mufflers. These rubber “insulators” are standard hardware on the Exiga’s exhaust to control movement and vibration.

On a 2011 Exiga, exhaust mounts (often called hangers or insulators) are the sturdy rubber pieces that hold the exhaust up under the car while isolating vibration from the cabin. They keep the mufflers and pipes correctly aligned so nothing knocks on the subframe, rear bumper, towbar, or suspension as the car flexes over bumps. Over time, heat, road grime, and a bit of coastal salt air can harden or crack the rubber. When that happens, the exhaust can sag, shift, and start to rattle.

For servicing, it’s smart to give the exhaust mounts a look whenever the car’s on a hoist—say at major services around 60,000–100,000 km, or any time an exhaust noise crops up. Typical symptoms that the Exiga’s mounts are past their best include:

• Rattles or thuds over bumps, especially from the rear
• A muffler sitting off-centre in the bumper cut-out
• Visible perishing, splits, or elongation of the rubber
• Excess vibration in the cabin at idle or on take-off

Replacement is straightforward for a trained tech. Let the exhaust cool, support the system, then slide the old mounts off the pegs (a dab of silicone spray helps). Fit quality OEM-spec rubber insulators to keep noise and harshness in check. Stiffer polyurethane hangers can be used if the car carries a heavy towbar or has an aftermarket exhaust, but they may transmit more vibration. After fitting, check clearances to heat shields, rear subframe, and bumper, and confirm the tips sit evenly.

In Aussie and Kiwi conditions, many Exigas still run original mounts well past a decade, but once they start sagging it’s best to replace the full set around the affected area so the alignment stays true. It’s a low-cost, high-impact fix that protects the rest of the exhaust from stress cracks and keeps the drive pleasantly quiet.

Popular questions about 2011 Subaru Exiga exhaust mounts

How often should the exhaust mounts be replaced?
There’s no strict interval, but they should be inspected at each major service. Many last 8–12 years depending on heat and climate. Replace at the first signs of perishing, sag, or rattle, or any time the exhaust position looks off.

Can aftermarket polyurethane hangers be used?
Yes. Poly hangers offer extra support for heavier or performance exhausts and can reduce movement. On a stock Exiga they’re optional, note they can add a touch more vibration compared with genuine-style rubber insulators.

What causes early failure of exhaust mounts?
Heat cycling, oil contamination, and coastal environments can age the rubber quicker. A bent exhaust or worn engine/trans mounts can also overload the hangers, shortening their life.
