Parts for your 2016 Subaru Forester-Exhaust gasket

2016 Subaru Forester exhaust gasket: what it does and when to replace it

Yes, the 2016 Subaru Forester uses exhaust gaskets. Subaru’s factory service information (STIS Service Manual, 2016MY Forester, Exhaust section) and the Subaru FAST/OEM parts catalogue list multiple exhaust gaskets for this model, including the cylinder head–to–exhaust manifold gasket, front pipe “donut” gasket, and rear/muffler flange gaskets. Turbo XT variants also use a turbo outlet–to–downpipe gasket. In short, exhaust gaskets are definitely relevant and fitted to 2016 Forester models.

On a 2016 Forester, the exhaust gasket’s job is to seal joints so exhaust gases flow cleanly through the system without leaking into the engine bay or underbody. At the front, multi‑layer steel manifold gaskets manage heat and pressure right at the ports. Further back, crush or “donut” gaskets take up slight movement and misalignment between flanges as the system heats, cools, and flexes. The seal keeps the note civil, the cabin free of fumes, and the O2 sensors reading accurately for good fuel economy.

While exhaust gaskets aren’t a routine replace‑every‑X‑kilometres item, they’re considered single‑use whenever an exhaust joint is undone. If the Forester’s exhaust comes apart for a clutch, turbo, manifold, or muffler job, fresh OEM‑spec gaskets should go in during reassembly. During regular servicing, it’s smart to check for tell‑tale signs of a leak and sort them early.

• Common signs of a leaking gasket: ticking on cold start, a raspy note under load, whiffs of exhaust near the bonnet or rear bumper, black soot at a flange, increased fuel use, or an emissions/rego or WOF fail.
• Best practice on replacement: use new gaskets only, clean and flatten mating faces, replace rusty studs and spring bolts, and torque fasteners to the Subaru spec. On XT models, pay extra attention at the turbo and downpipe joints due to heat cycling.
• Good preventative habits: avoid prying flanges, support the system so hangers aren’t loaded, and after off‑road work or a scrape, have a quick look for bent flanges or fresh soot.

Done properly, a simple gasket swap is a short job that saves headaches later. It keeps the Forester quiet, legal, and efficient—exactly how most owners like it.

Popular questions about 2016 Subaru Forester exhaust gaskets

Does a 2016 Subaru Forester have exhaust gaskets?
It does. Both the non‑turbo (FB25) and turbo (FA20F XT) models use several exhaust gaskets, including the manifold gasket and the front pipe donut gasket. The turbo adds a gasket between the turbo outlet and downpipe.

How often should exhaust gaskets be replaced?
They’re replaced when disturbed or if there’s evidence of a leak. Any time an exhaust joint is undone, fit new gaskets. Otherwise, inspect at service time and replace if you see soot, hear a tick, or smell fumes.

Is it safe to drive with a leaking exhaust gasket?
It’s not recommended. Leaks can let fumes into the cabin, skew O2 readings, and in some cases overheat nearby components. Short trips to a workshop are usually fine, but book a repair promptly.
