Parts for your 2022 Subaru Impreza-Exhaust mount

2022 Subaru Impreza exhaust mounts: what they do and when to replace them

Yes — exhaust mounts are fitted and very relevant on the 2022 Subaru Impreza. Technical sources including the Subaru Impreza (2017–2023) Workshop/Service Manual (Exhaust System > Muffler & Pipe) and the official Subaru parts catalogue for MY2022 list the rubber “exhaust insulator” hangers and their brackets that suspend the centre pipe and rear muffler from the body. These factory references confirm the Impreza’s exhaust is supported by multiple rubber mounts to control height, alignment, and vibration.

On this model, the exhaust mounts (often called rubber hangers or insulators) keep the system properly located under the car, isolate vibration from the cabin, and allow a bit of controlled movement so the exhaust can expand and flex without cracking. When those rubber bushes harden, crack or stretch, owners may notice rattles, a droopy tailpipe, or extra vibration and droning inside the car. Left too long, a sagging system can stress joints, gaskets, and heat shields.

As part of routine servicing in Australia and New Zealand, it’s smart to have the exhaust mounts visually checked whenever the car’s on a hoist—typically with each scheduled service. Coastal conditions and big temperature swings can accelerate rubber ageing, so regular inspections pay off. Technicians look for perished rubber, splits, shiny witness marks from contact, or a muffler sitting off-centre.

• Common signs it’s time to replace: thumps over bumps, exhaust contacting the subframe, sagging height, excess cabin vibration, or visible cracking in the rubber.
• Good practice: replace mounts in pairs or as a small set so the system sits evenly.
• Fitting tips: support the exhaust with a jack and wood block, use silicone spray on the pegs, and refit brackets to factory specifications.

Owners choosing upgrades can stick with genuine-style rubber for comfort or go for stiffer performance mounts to tighten up movement (noting they can transmit a touch more vibration). After installation, a quick alignment check ensures the tailpipe clears the bumper and heat shields with healthy gaps. With fresh mounts, the Impreza’s exhaust sits where it should, stays quiet, and avoids undue stress on welds and flanges—exactly as Subaru’s service literature intends.

Popular questions about 2022 Subaru Impreza exhaust mounts

How many exhaust mounts does a 2022 Impreza have?
It varies by body style and trim. The system is typically supported by multiple rubber insulators along the mid-pipe and at the rear muffler. A technician will confirm the exact count on the hoist, as market equipment and muffler layout can differ.

Can worn mounts cause vibration or droning?
They can. When the rubber perishes or stretches, the exhaust can contact the body or sit misaligned, transmitting more vibration into the cabin and sometimes creating a low-frequency drone. Restoring correct height and isolation with fresh mounts usually brings the cabin back to its normal refinement.

How often should they be replaced?
There’s no fixed kilometre interval in Subaru’s literature because service life depends on climate and driving. A quick check during each scheduled service is recommended. If cracks, hardening, or sagging are found, replace sooner rather than later to protect gaskets, flex joints, and heat shields.
