Parts for your 2012 Subaru Forester-Exhaust mount

2012 Subaru Forester exhaust mount — what it is and when to replace it

Yes, the 2012 Subaru Forester uses exhaust mounts (rubber exhaust hangers). This is confirmed by Subaru’s factory workshop manual for the SH Forester (Exhaust System section) and Subaru’s parts catalogues, which list multiple rubber hangers supporting the front pipe, centre section, and rear muffler. Independent repair guides such as the Haynes Forester 2009–2014 manual also detail inspection and replacement of these mounts.

On this Forester, the exhaust mounts suspend the exhaust off the body, isolate vibration, and allow the system to move with heat expansion without knocking on underbody components. They’re simple rubber isolators that slide over pegs on the chassis and exhaust brackets. Depending on spec, there are typically three to five mounts: near the transmission crossmember/front pipe, mid-section (resonator), and two at the rear muffler.

Because they live under the car and deal with heat, road grime, and spray, the rubber can harden, crack, or stretch over time. Tell-tales include a muffler that sits low or off-centre, thumps over bumps, or a buzz at idle. If the tailpipe looks crooked or the exhaust taps the subframe, the mounts are prime suspects.

• Inspection: Check at every service or 20,000 km. Look for perishing, splits, elongation, or shiny rub marks nearby that suggest contact.
• Replacement tips: Support the exhaust with a jack and wood block. Spray silicone lube on the pegs, then lever the old mounts off. Fit quality OEM or high-temp aftermarket rubbers. Replace mounts in pairs on the same section to keep things even.
• Hardware: Inspect hanger brackets and bolts for rust. Tighten to factory spec from the Subaru manual. A dab of anti-seize on metal studs helps next time (avoid contaminating the rubber).
• After fitting: Centre the muffler in the bumper cut-out and ensure at least a finger’s clearance to heat shields and suspension arms.

In short, exhaust mounts are a small, inexpensive part that makes a big difference to cabin comfort and exhaust longevity. Keeping them fresh on a 2012 Forester helps prevent rattles, stress on joints, and premature failure of flanges and gaskets.

Popular questions about 2012 Subaru Forester exhaust mounts

How many exhaust mounts does a 2012 Forester have?
Most SH Foresters run three to five rubber mounts depending on trim and exhaust layout. You’ll usually find one near the front pipe area, one mid-section, and a pair at the rear muffler. Always inspect the full length to be sure.

What are the signs my exhaust mounts need replacing?
Look for a sagging or off-centre muffler, knocking over bumps, buzzing/vibration at idle, and visible cracks or stretched rubber. If the tailpipe has started tapping the bumper or a heat shield, the mounts are likely due.

Can universal hangers be used on a 2012 Forester?
Good-quality universal hangers can work if the hole spacing and thickness match, but OEM-spec rubber gives the right stiffness and fit. If going universal, choose high-temp rubber and match the length so the system sits correctly.
