Parts for your 2016 Subaru Legacy-Exhaust mount

2016 Subaru Legacy Exhaust Mount

Yes — the 2016 Subaru Legacy is fitted with exhaust mounts (also called exhaust hangers or insulators). This is confirmed by the Subaru Service Manual for 2015–2017 Legacy/Outback in the Exhaust section, which details removal and installation of hangers/insulators, the Subaru FAST electronic parts catalogue for the BN/BS Legacy, which lists exhaust hangers and brackets throughout the system, and common repair references such as the Haynes Subaru Legacy & Outback 2010–2019 manual that specify inspecting and replacing perished exhaust insulators.

On the 2016 Legacy, the exhaust mounts are tough rubber insulators and brackets that suspend the exhaust from the body. Their job is twofold: keep the pipework and mufflers correctly aligned, and isolate vibration so the cabin stays quiet. With Subaru’s AWD layout routing the system around the rear diff and subframes, several mounts share the load from the front pipe to the twin rear mufflers, preventing knocks under acceleration, over bumps, or on rough roads.

As part of routine servicing, it’s smart to give the mounts a once-over. Rubber hardens, cracks, and sags with age, heat, and coastal conditions common across Australia and New Zealand. A quick visual check during an oil service or WOF/rego prep can save a rattle chase later. Look for stretched or split rubber, excessive sag at the mufflers, or shiny scuff marks where the exhaust has been kissing a crossmember or heat shield. If one mount is cactus, replace it and inspect its neighbours — they’ve done the same mileage.

When fitting new mounts, support the exhaust so there’s no load on the brackets. A spritz of silicone spray helps the pegs slide in and out of the rubber, avoid petroleum-based greases that can attack the insulator. Refit any brackets and torque to the spec in the Subaru service manual, then check clearances around the subframes and bumper. Using OE or OE-equivalent insulators with the correct durometer (stiffness) keeps the note civil and the system stable. Universal hangers can work in a pinch, but the wrong length or softness can cause drumming or contact under load.

• Common signs it’s time: exhaust thumps on start-up or over bumps, new cabin buzzes, a droopy tailpipe, or visible cracks in the rubber.
• Inspection cadence: at each service or roughly every 10,000–15,000 km, sooner if driving on corrugations or near salt air.

Popular questions about 2016 Subaru Legacy exhaust mounts

Do all 2016 Subaru Legacy models have exhaust mounts?
They do. Every trim uses multiple rubber hangers and brackets to suspend the exhaust. The exact count and layout can vary slightly by engine and market spec, but front, mid, and rear sections are all supported by insulators to control movement and noise.

How often should the exhaust mounts be replaced?
There isn’t a fixed interval. Instead, inspect them at each service and replace when perished, cracked, sagging, or if the exhaust starts knocking. In typical AU/NZ use, many last 5–10 years, but coastal exposure, heat, and gravel roads can shorten that.

Can universal hangers be used on a Legacy?
Universal rubber hangers can get you out of trouble, but match the hole spacing and thickness to maintain correct exhaust height and clearance. For best NVH and fit, OE-style insulators designed for the BN/BS Legacy are the safe bet.
