Parts for your 2010 Subaru Impreza-Exhaust mount

2010 Subaru Impreza Exhaust Mount

Yes, the 2010 Subaru Impreza uses exhaust mounts (also called hanger insulators), and they’re absolutely relevant. The Subaru 2010MY Impreza Service Manual (STIS) in the Exhaust System section specifies removing and refitting the “cushion rubber” from the hangers during exhaust work, and the Subaru Electronic Parts Catalogue lists multiple rubber hanger insulators for the GE/GH/GR/GV chassis (commonly referenced as the exhaust pipe support/insulator, e.g., typical Subaru hanger insulator part family like 44059AE000). These factory sources confirm the vehicle relies on rubber mounts to suspend the exhaust.

The exhaust mounts on a 2010 Impreza keep the system securely suspended under the car while isolating noise and vibration. They stop the muffler and pipes from knocking the body, keep the tips centred in the bumper cut-out, and maintain clearance to the rear diff, subframes, and heat shields. On this model there are several mounts from the centre pipe through to the rear muffler, with a brace (“stay”) near the front pipe to control movement under load. Good mounts mean a quiet cabin, tidy tailpipe alignment, and fewer dramas off the line or over corrugations.

As part of regular servicing, it’s smart to inspect the mounts every 10,000–20,000 km or whenever the exhaust has been disturbed. Look for perished or hardened rubber, cracks, elongated holes, sagging, or oil contamination. Also check the welded metal hanger rods and brackets for rust or fractures, and make sure heat shields aren’t touching. Confirm the muffler sits even and there’s proper clearance around the rear bumper and driveline.

• Common signs it’s time to replace: rattles at idle or on start-up, thuds over bumps, exhaust tips sitting off-centre, or the system visibly low or skewed.

Replacement is straightforward with the right approach. Support the exhaust with a jack and a wood block so there’s no strain on the remaining mounts. A quick spritz of silicone spray or rubber-safe lubricant helps the insulators slip off and on. Avoid levering on thin-walled pipe, use the hanger rods. Fit quality OE-style rubber insulators for factory comfort, or consider polyurethane if the car sees rough roads and you want firmer control (expect a touch more NVH). Tighten any brackets and flanges to the torque settings in the Subaru service manual, re-check tip alignment, and road test. After a few days, give everything a once-over to make sure the mounts have settled nicely and clearances are sweet.

Because the Impreza is AWD, pay extra attention to clearances around the rear subframe and diff, and ensure heat shields aren’t singing against the pipe after the new mounts bed in.

Popular questions about 2010 Subaru Impreza exhaust mounts

How many exhaust mounts does a 2010 Impreza have?
Most 2010 Imprezas run several rubber insulators from the centre pipe to the rear muffler, typically three to five depending on body style and exhaust layout. Turbo models and certain trims can have an extra mount or different bracket positions. A quick look under the car will show each rubber hanger at the muffler and along the mid-section.

What symptoms point to worn mounts on this model?
Expect rattles at idle, a dull thud over bumps, or the muffler sitting low or off-centre in the bumper. You might also notice the system moving more than usual when you blip the throttle. Visual checks often reveal cracked or stretched rubber, or shiny contact marks where the exhaust has been touching a shield or crossmember.

Should I choose OEM rubber or polyurethane hangers?
OEM-style rubber keeps factory refinement and is ideal for daily use. Polyurethane is firmer, great for rough roads or spirited driving because it controls movement better, but it can pass a little more vibration into the cabin. Many owners go OEM for comfort unless there’s a specific need for extra stiffness.
