Parts for your 2016 Subaru Forester-Exhaust mount

2016 Subaru Forester exhaust-mount: what it does, why it matters, and when to replace it

Yes, the 2016 Subaru Forester absolutely uses exhaust mounts (also called hangers or insulators). This is confirmed by Subaru’s 2016 Forester Service Manual (Exhaust section), which details the removal/installation of exhaust hangers and brackets along the centre and rear pipes, and by Subaru genuine parts catalogues listing rubber exhaust insulators and muffler hanger brackets for the SJ-series Forester. These rubber mounts support the exhaust while isolating vibration from the body.

On the 2016 Forester, the exhaust-mounts sit at strategic points from the front pipe back to the rear muffler, cradling the system so it doesn’t clout the underbody over bumps. They let the system expand with heat and move slightly on rough roads without transferring harshness into the cabin. When they perish, stretch, or split, the exhaust can sag, rattle against heat shields, or thud over driveways. Left too long, a droopy system can stress joints and flanges, leading to leaks and cracked welds.

As an easy win during regular servicing, exhaust-mount inspection should be on the list every 10,000–15,000 kilometres (or at each scheduled service). Look for cracked rubber, elongated holes, shiny contact marks on pipes or shields, and any change in tailpipe height. A silicone-safe spray makes removal simpler, support the exhaust, slip the old insulator off the pegs, and press on a quality replacement. Bracket fasteners should be tightened to the factory spec from the Subaru service manual rather than “by feel”.

Owners who tow, drive corrugated roads, or have the turbo XT variant will benefit from more frequent checks. If one insulator has failed, it’s smart to replace the set on that section so the system sits level. Avoid ultra-stiff universal mounts that can transmit vibration or alter alignment, OE-style rubber or reputable polyurethane units are the safer bet. Keep heat shields intact so the rubber doesn’t cook, and recheck clearances after any exhaust work or rear bumper tweaks.

• Tell-tales it’s time: new rattles at idle, a drum-like thud on take-off, visible sag, or the tailpipe kissing the bumper cut-out.
• Pro tip: a dab of silicone grease on the pegs speeds future servicing without attacking the rubber.

Popular questions

How many exhaust mounts are on a 2016 Subaru Forester?
Most 2016 Foresters run multiple rubber hangers from the mid-pipe to the rear muffler, with additional brackets at the body. The exact count varies slightly by variant (2.5i vs XT and market exhaust spec), but expect several insulators supporting the centre and rear sections.

When checking, follow the exhaust from front to back and inspect each hanger and bracket point. If one looks tired, assess the neighbours too so the system stays evenly supported.

Can a home DIYer replace the exhaust-mounts?
Yes, it’s a straightforward DIY if the car is safely raised and the exhaust is cool. Support the pipe with a jack and timber block, lube the pegs with silicone spray, and lever the old insulator off. Press the new one on and confirm the exhaust sits centred with good clearance.

If bolts for a hanger bracket are removed, tighten them to the Subaru service manual spec. When in doubt about access or rusted hardware, a workshop lift and rattle gun save time and knuckles.

What are the signs of a failing exhaust-mount?
Common giveaways include a sagging tailpipe, knocking over speed humps, buzzes at certain revs, or new contact marks on heat shields. You might also smell fumes if a stressed joint starts leaking.

Catching these early keeps the exhaust off the body and prevents damage to flanges and welds, especially on vehicles that tow or see rough tracks.
