Parts for your 2017 Subaru Exiga-Exhaust mount

2017 Subaru Exiga exhaust mount (hanger/insulator) — purpose, care and replacement

Yes — the 2017 Subaru Exiga uses exhaust mounts (also called hangers or insulators). Subaru’s factory literature lists them as “Insulator – Exhaust” or “Exhaust Pipe Hanger” in the YA-series Service Manual (Exhaust section) and in Subaru’s FAST electronic parts catalogue, with genuine parts typically in the 44022-xxxxx family. These rubber isolators are standard fitment and essential to how the Exiga’s exhaust is supported and quietened.

On the Exiga, the exhaust mounts suspend the front pipe, centre section and rear muffler from the body while soaking up engine vibration and road shock. They let the exhaust move a little as the system heats up and grows in length, keeping metal off metal so there’s no annoying thumps, buzz or drone in the cabin. If a mount perishes or stretches, the muffler can sit low, the pipe can tap on a crossmember, and the whole system can feel loose.

As part of routine servicing, it’s smart to give the mounts a once-over every 20,000 km or at least annually — even more often if the Exiga sees gravel roads, kerb strikes or coastal conditions. Look for cracked or hardened rubber, splits around the holes, excessive sag, or shiny rub marks on the exhaust where it’s been touching. Also check the steel hanger rods for rust pitting and the nearby brackets for looseness.

Replacement is straightforward: safely support the exhaust, mist some silicone spray on the old insulators, unhook them, then press on fresh mounts and confirm the system is centred with good clearance around heat shields and the rear bumper. Always tighten brackets to workshop specs from the Subaru manual. Skipping mounts or tying the exhaust up with wire is a no-go — it transmits vibration and can crack welds or pipes.

For parts choice, OEM-style rubber suits daily use with the Exiga’s stock system, offering the best noise isolation. Stiffer polyurethane hangers can help if the vehicle runs a heavier stainless system or sees spirited driving, but they may raise cabin vibration a touch. If the exhaust has been upgraded, replacing all mounts together is a tidy way to reset height and alignment.

• Common signs of tired mounts: clunks over bumps, rattles at idle, exhaust sitting wonky, or fresh scrape marks.
• Typical service life: 5–10 years or 100,000–200,000 km, depending on heat, load and climate.
• Tip: a small dab of silicone spray makes install and alignment far easier.

FAQs — 2017 Subaru Exiga exhaust mount

How often should the Exiga’s exhaust mounts be replaced?
There’s no strict interval, but many will be due somewhere between 5–10 years or 100,000–200,000 km. Heat, towing, rough roads and coastal air can shorten their life. Replace them when cracks, sagging or vibration show up rather than waiting for a rattle to turn into a bigger issue.

Are polyurethane exhaust mounts a good idea on a 2017 Exiga?
They can be, especially with a heavier aftermarket exhaust or if the car regularly carries a load. Poly mounts reduce movement and help keep clearances consistent, but they can pass a bit more vibration into the cabin. For a quiet, family-friendly ride, fresh OEM-style rubber is usually the sweet spot.

What are the symptoms of a failing exhaust mount on this model?
Listen and look for a dull knock over bumps, a buzz at idle, the muffler sitting low or off-centre, or visible splits in the rubber. You might also find the tailpipe hitting the bumper cut-out or the mid-pipe scuffing a crossmember or heat shield.
