Parts for your 2012 Subaru Exiga-Exhaust mount

2012 Subaru Exiga exhaust mount — what it does and when to replace it

Yes, the 2012 Subaru Exiga is fitted with exhaust mounts (often called exhaust hangers or cushions). This is supported by Subaru’s Factory Service Manual for the Exiga YA-series (Exhaust section: removal/installation and inspection procedures) and the Subaru electronic parts catalogue illustrations for the 2012 Exiga, which show multiple rubber hanger insulators at the centre pipe and rear muffler, plus bracketry to the body. So, exhaust mounts are absolutely relevant on this model.

On the Exiga, the exhaust mounts’ job is to hold the exhaust in the right place, isolate vibration, and allow the system to move slightly as it heats and cools. Those rubber cushions stop the muffler knocking the subframe over bumps, keep the tips centred in the bumper cut-out, and protect welds, flanges, and oxygen sensor wiring from stress. Without healthy mounts, the exhaust can sag, rattle, and load up gaskets and joints, which can lead to leaks and premature repairs.

Given a 2012 Exiga is well over a decade old now, the original rubber often hardens, cracks, or stretches. Subaru service literature lists exhaust hangers as an inspection item whenever the exhaust is removed and during routine checks, and that’s smart practice at each service or every 10,000–15,000 km. A quick visual once-over can save headaches later.

• What to look for: perished or cracked rubber, stretched “donut” holes, shiny contact marks from the exhaust touching the body, and a droopy rear muffler.
• Common symptoms: thumps over speed humps, a metallic rattle at idle, exhaust tips sitting off-centre, or a new buzz in the cabin.

Replacement is straightforward if the exhaust is cool and properly supported. A dash of silicone spray or soapy water helps slide the old hangers off the pegs. Swap like-for-like quality rubber insulators rather than ultra-hard aftermarket pieces that can feed vibration back into the cabin. If one is tired, it’s often worth replacing the set so the system sits square. Refit any brackets and torque fasteners to the Subaru spec in the service manual, then check clearances around the subframe, tailgate bumper trim, and heat shields.

Pro tip: avoid petroleum-based lubes on the rubber, and always double-check oxygen sensor wiring and heat shields while you’re under there—easy wins during the same job.

Popular questions

How many exhaust mounts does a 2012 Subaru Exiga have?
Most Exiga variants use several rubber hangers across the centre pipe and rear muffler, typically three to five in total depending on trim and exhaust layout. The exact count and style are shown in the Subaru electronic parts catalogue for the specific VIN.

Can the exhaust mounts be replaced at home?
Yes, with the car safely on stands and the exhaust supported. It’s mainly a matter of sliding the old rubber cushions off and fitting new ones. Stubborn hangers respond well to silicone spray or soapy water. If rusted brackets are involved, a workshop may be quicker and safer.

What happens if worn mounts aren’t replaced?
Expect rattles, knocks, and poor exhaust alignment. Over time that can stress flanges, flex joints, and sensors, and may even melt bumper trim if the tip shifts. Fresh mounts restore correct height and clearance, reducing noise and preventing costly follow-on damage.
