Parts for your 2013 Subaru Outback-Exhaust mount

2013 Subaru Outback exhaust-mount: what it is, why it matters, and when to replace it

Yes, the 2013 Subaru Outback uses exhaust mounts (also called exhaust hangers or insulators). Subaru’s Factory Service Manual for the 2010–2014 Outback/Legacy platform describes the exhaust system being supported by rubber “insulators” at the front pipe, centre section, and muffler positions, and the Subaru Electronic Parts Catalogue (EPC/FAST) lists these insulators as service parts for that model year. Those technical sources confirm the part is fitted and serviceable on the 2013 Outback.

On this Outback, the exhaust-mount’s job is straightforward but important: it holds the exhaust in the right place under the car while isolating noise and vibration. The rubber insulators let the system move slightly as the engine rocks and the pipework heats and cools, preventing knocks against the body and reducing drone in the cabin. If a mount perishes, stretches or tears, the exhaust can sit low, rattle over bumps, or put stress on flanges and welds.

As part of routine servicing, it’s smart to check the exhaust mounts any time the car’s on a hoist—say every 10,000–15,000 kilometres or annually. Look for cracked rubber, shiny witness marks where the system has been touching the body, a droopy tailpipe, or fresh soot near joints (a hint something’s under strain). If one mount has failed, the rest are often tired, replacing them as a set keeps the system aligned and quiet.

Replacement is a quick, affordable job. A spritz of silicone spray helps slide the old insulators off the pegs. Fit quality rubber or upgraded high-temp mounts, make sure the brackets aren’t bent, and recheck the exhaust sit—clearances around the subframe, heat shields and bumper should be even. Aftermarket tow bars and bushings can change clearances, so a quick road test for knocks is worth it. In Aussie and Kiwi conditions—heat, road grime, beach trips—rubber can age faster, budgeting for fresh mounts every few years is normal.

• Common symptoms: rattles or thumps over bumps, exhaust hanging low, extra vibration at idle, or clunking on start-up/shut-down.
• Good practice: inspect on every service, replace in pairs or as a set, and verify clearances once fitted.

FAQs

How many exhaust mounts does a 2013 Subaru Outback have?

Most 2.5i models use around four rubber insulators across the front, mid and rear sections. The 3.6R, with twin rear mufflers, typically uses five or six. Exact count can vary with trim and market, a quick look under the vehicle will confirm what’s fitted.

What are the signs the exhaust mounts need replacing?

Rattles over rough roads, a droopy tailpipe, new vibrations at idle, or clunks as the engine starts or stops are classic tells. Visually, cracked or stretched rubber and fresh contact marks on heat shields or the underbody mean the mounts are past their best.

Is it safe to drive with a broken exhaust mount?

Short trips might be possible, but it’s not ideal. A failed mount can let the exhaust shift, stressing joints and risking a partial drop or a leak. It’s best to sort it promptly to avoid bigger repairs and keep the cabin quiet and fume-free.
