Parts for your 2020 Subaru Outback-Exhaust mount

2020 Subaru Outback exhaust-mount — what it does and when to replace it

Yes, the 2020 Subaru Outback is fitted with exhaust mounts (also called exhaust hangers or insulators). Technical sources including the Subaru Service Manual for the 2020 Outback/Legacy (Exhaust System section) and Subaru Genuine Parts catalogues list multiple rubber “insulator–exhaust” mounts supporting the mid-pipe and rear muffler assemblies. These flexible mounts are standard NVH (noise, vibration, harshness) hardware on Subaru’s Global Platform vehicles and are also cross-listed by major aftermarket catalogues for direct fitment on MY20 Outback.

On this Outback, the exhaust-mounts hold the system in the correct position under the car while isolating vibration from the cabin. They let the stainless piping and mufflers move slightly with engine rock and heat expansion, but they prevent knocks against the underbody, bumper, and suspension. That balance keeps things quiet, protects welds and flex joints, and helps maintain ground clearance on rough Kiwi and Aussie roads.

Over time, rubber mounts harden, crack, or stretch from heat, ozone, and road grime. If an Outback’s exhaust starts to drone more than usual, rattles over bumps, or the tailpipe looks a bit low or off-centre, tired mounts are often the cause. During routine servicing, it’s smart to glance at each mount for splits, glazing, or elongation. Many techs will give them a quick push test: excessive movement or a perished look means it’s time.

• Inspection tip: check mounts whenever the car’s on a hoist for oil or brake service, or roughly every 20,000–30,000 km.
• Replacement advice: do them in sets on the affected section (e.g., both rear muffler mounts) to keep tension even.
• Fitting tip: use silicone spray to slip new mounts on, avoid petroleum-based lubricants that can degrade rubber.
• Hardware: if a bracket bolt is corroded, replace it and tighten to the workshop manual torque spec for that bracket.

Those who tow, travel corrugated roads, or drive off the beaten track may need mounts a bit more often. Firmer aftermarket options exist to limit movement, but they can slightly increase cabin vibration. Genuine-style rubber keeps that factory-quiet feel most Outback owners prefer.

How many exhaust mounts does a 2020 Subaru Outback have?

Typically several, positioned along the mid-pipe and at the rear mufflers to support the system. The exact count can vary slightly with market spec and exhaust layout. A parts diagram check by VIN will confirm the precise number on a given vehicle.

What are the signs an exhaust mount needs replacing?

Common clues include a drooping or off-centre tailpipe, new rattles or clunks over bumps, and increased droning in the cabin. On inspection, the rubber may look cracked, glossy/hardened, or stretched, allowing the exhaust to sit low or contact shields and brackets.

Is it okay to keep driving with a broken exhaust mount?

It’s not recommended. A failed mount can let the exhaust move excessively, stressing flanges, flex joints, and O2 sensor wiring. It may also bang on the body or scrape on driveways. Replacing the mount promptly helps avoid pricier exhaust repairs.
