Parts for your 2006 Subaru Outback-Exhaust mount

2006 Subaru Outback exhaust-mount: what it does and how to look after it

Based on technical references – including the Subaru Legacy/Outback 2005–2009 Service Manual (Exhaust section), the Subaru genuine parts catalogue that lists “Insulator – Exhaust” for the 2006 Outback (e.g., common references include 44022AE021 among others), and general repair guides such as the Haynes Subaru Legacy & Outback 2000–2009 – the 2006 Subaru Outback definitely uses exhaust-mounts (rubber hanger insulators). They suspend the exhaust under the car and isolate vibration, so the system can move a touch with the drivetrain without thumping the body.

On this model, several rubber exhaust-mounts support the front pipe, mid‑section and rear muffler. Their job is to keep the exhaust aligned and off the underbody, maintain ground and driveline clearance (important on Outback’s raised suspension), and reduce noise and harshness in the cabin. When the mounts harden, crack or stretch, the exhaust can droop, rattle on crossmembers or heat shields, and place stress on flanges and gaskets – a quick way to end up with leaks or a droney note.

As part of routine servicing of a 2006 Subaru Outback exhaust-mount setup, it’s smart to inspect the hangers every 20,000–30,000 kilometres or at each oil service if you regularly see gravel roads, towing, or coastal conditions. Look for perished rubber, splits, elongation of the holes, or shiny scuff marks where the exhaust has been contacting the body. A quick wobble test of the muffler can reveal excess play.

• Signs it’s time to replace: clunks over bumps, new vibration or drone, sagging tailpipe, or visible cracks in the rubber.
• Replacement tips: let the exhaust go stone cold, support it with a jack and wood block, spray silicone lube on the hanger pegs, and swap one mount at a time.
• Parts choice: OEM-style rubber keeps noise levels civil. Polyurethane options are tougher but can add a bit more NVH.

If a mount failed due to a seized bracket or a bent hanger rod, sort that hardware too. A dab of anti-seize on the steel pegs helps the next service. Aftermarket systems may add or relocate mounts, so match the hanger style to your specific exhaust. DIY is straightforward with basic spanners and stands, but if rusted fasteners or alignment look sketchy, a workshop can handle it quickly.

Popular questions about 2006 Subaru Outback exhaust-mount

How many exhaust-mounts does a 2006 Outback have?
Most Australian/NZ market cars typically run about four rubber hangers: one near the front pipe, one mid‑section, and two at the rear muffler. Some variants or aftermarket systems may add an extra mount for support.

What part numbers fit the 2006 Outback?
Common Subaru listings call the piece “Insulator – Exhaust.” Frequently referenced numbers include 44022AE021 and related supersessions. Exact fit can vary by engine (2.5i vs 3.0R) and exhaust layout, so confirm against your VIN or the stamping on your existing mounts.

Will stiffer polyurethane mounts increase vibration?
Usually yes. Poly hangers control movement better and last longer, but they can pass more vibration into the cabin. For daily road use, OEM‑style rubber is a comfy, quiet pick, choose poly if you want extra support for performance or heavy towing.
