Parts for your 2019 Subaru Impreza-Exhaust mount

2019 Subaru Impreza exhaust-mounts

Yes, the 2019 Subaru Impreza is fitted with exhaust-mounts (also called exhaust hanger insulators). Subaru’s factory Service Manual for the 2019MY Impreza (GK/GT chassis), in the EX (H4 SOHC) Exhaust System section, shows the centre pipe and rear muffler supported by rubber insulators on welded hanger rods. Genuine Subaru parts catalogues used by dealers list these as “Insulator – Exhaust” at multiple positions along the system. That means exhaust-mounts are absolutely relevant on this model.

On the Impreza, the exhaust-mounts are the small but mighty rubber isolators that suspend the exhaust under the car, keeping the pipes and muffler correctly aligned while soaking up vibration. They stop the system thumping the body, reduce cabin buzz, and protect the welds and flanges from stress. When these mounts harden, stretch, or crack with age, the exhaust can sit low, rattle over bumps, or knock on the subframe—annoying at best and potentially damaging if left too long.

As part of routine servicing, it’s smart to eyeball each exhaust-mount from the front pipe back to the rear muffler. On a 2019 Impreza that’s done mixed city–highway work, the originals typically last many years, but climate, heat cycles, and road grime can age the rubber faster. During an oil service or brake check, a quick inspection for perishing, tearing, glazing, or excessive elongation is worthwhile. Any mount that’s cracked or sagging should be replaced, and it’s good practice to do them in pairs across the same section so heights match.

• Listen for new rattles or a hollow “clunk” over speed humps.
• Look for a tailpipe sitting off-centre or hanging lower than usual.
• Check for shiny contact marks where the muffler has touched heat shields.
• Note extra vibration at idle with the A/C on—often a tired mount.

Replacement is straightforward for a workshop: support the exhaust, lube the pegs, swap the insulators, and ensure clearances to the body and bumper are spot-on. Quality OEM-style rubber is ideal for everyday driving, stiffer aftermarket options can reduce movement but may add a touch of cabin feel. After a kerb strike or off-road scrape, get the mounts rechecked—keeping the system properly supported helps prevent leaks and preserves that quiet, factory sound over the long haul.

• Does the 2019 Subaru Impreza actually have exhaust-mounts?
  Yes. The Subaru Service Manual for the 2019MY Impreza shows multiple rubber hanger insulators supporting the centre pipe and rear muffler, and dealer parts catalogues list them as “Insulator – Exhaust” at the factory mounting points.
• How often should the exhaust-mounts be replaced?
  There’s no fixed kilometre interval. Inspect them at each service and replace when the rubber shows cracking, stretching, hardening, or if you notice rattles, sagging, or contact with heat shields. Many last 5–10 years depending on climate and use.
• Is it okay to drive with a broken exhaust-mount?
  It’ll usually still move the car, but it’s not a great idea. A loose exhaust can bang on the body, stress welds and joints, and may get noisy enough to attract attention at a WoF or roadside check. Fix it promptly to avoid knock-on damage.
