Parts for your 2001 Subaru Forester-Exhaust mount

2001 Subaru Forester exhaust-mount (hangers): purpose, care and when to replace

Yes, the 2001 Subaru Forester absolutely uses exhaust-mounts (rubber hangers/insulators). This is documented in the Subaru Factory Service Manual for MY2001 Forester (Exhaust section), the Subaru FAST electronic parts catalogue for SF-series Forester, and general repair guides such as the Haynes manual covering late-1990s to mid-2000s Subaru Forester models. These sources show multiple rubber insulators supporting the mid-pipe and rear muffler, plus brackets fixed to the body and subframes.

On this Forester, the exhaust-mounts suspend the exhaust so it can move slightly without knocking the body, while isolating vibration and heat from the cabin. Each rubber insulator carries the weight of a section (mid-pipe, resonator, muffler) and keeps the system aligned so flanges and joints aren’t put under stress. When they age, the rubber hardens, cracks or sags, which lets the muffler sit low, rattle over bumps, or thump on acceleration.

As part of routine servicing on a 2001 Forester, it’s smart to check every exhaust mount and bracket at each oil service or 10,000–15,000 km. Look for:

• Perished, cracked or oil-soaked rubber insulators
• Muffler or mid-pipe sitting crooked or too close to the rear crossmember or towbar
• Metal bracket corrosion, missing hardware, or elongated hanger pegs
• Contact marks on the body, heatshields, or rear diff carrier

Replacement is straightforward with the vehicle safely supported. Spritz silicone spray on the pegs, lever the old insulator off, and match it with an OEM-quality rubber or a known-good polyurethane alternative. Refit in the same orientation, then check clearances with the vehicle at normal ride height. If one mount has failed on this high-mileage era of Forester, it’s often worth swapping the set so the exhaust sits true and vibration stays low.

Tips a workshop will follow on a 2001 Forester:

1. Inspect heatshields and flange springs while under there—tired mounts can stress those parts.
2. Avoid jacking under the exhaust, it can crease the pipe and ruin alignment.
3. After any mount change, start the car, blip the throttle, and watch for excessive movement or knocks.
4. Choose stock-style rubber if cabin comfort is the priority, firmer mounts can add a bit of NVH.

Left too long, failed mounts won’t usually cause a leak by themselves, but they can crack welds, chew out gaskets, and make the car feel and sound rough as guts. Keeping the exhaust-mounts fresh on a 2001 Forester keeps the system quiet, stress-free, and compliant—exactly how Subaru intended.

FAQs

How many exhaust mounts does a 2001 Subaru Forester have and where are they?

Most 2001 Foresters run several rubber insulators: typically one near the front of the mid-pipe/resonator area and two at the rear muffler (left and right), plus associated metal brackets. Exact count can vary with market equipment (towbar, heatshield style, and emission hardware). A quick look under the back bumper will usually reveal the two rear muffler hangers hooked to body-mounted brackets.

When in doubt, follow the exhaust from the catalytic converter back and note each rubber insulator supporting a peg on the pipe or muffler. If a towbar has been fitted, check for an extra bracket or altered clearances near the rear crossmember.

What are the signs the exhaust mounts need replacing on a 2001 Forester?

Common giveaways are a droopy or off-centre muffler, clonks over bumps, or a dull thud when taking off or backing off the throttle. The rubber may look cracked, shiny from oil contamination, or stretched thin. Sometimes there’s a rattle at idle where the exhaust taps a heatshield or subframe.

If left, the excess movement can stress flanges and welds, so it’s best to swap tired mounts early. They’re inexpensive and make a noticeable difference to refinement.

Can polyurethane exhaust mounts be used on this model?

Yes, firmer polyurethane mounts can reduce movement and keep the system tucked up—handy on rough roads or with heavier aftermarket systems. The trade-off is a touch more vibration transmitted into the cabin, especially at idle with auto transmissions or stiffer engine mounts.

For a daily-driven 2001 Forester chasing comfort, fresh OEM-style rubber is usually the sweet spot. For off-road touring or performance use, quality poly can be a good call, fitted as a matched set and checked for clearances.
