Parts for your 2014 Subaru Forester-Exhaust gasket

2014 Subaru Forester exhaust gasket — what it does and when to replace it

Per the Subaru Forester (SJ, 2014) Service Manual — Exhaust System section — and the Subaru Electronic Parts Catalogue (Group 44: Exhaust), the 2014 Forester absolutely uses exhaust gaskets. Both the 2.5i (FB25) and the 2.0XT turbo (FA20F) have multiple sealing points: cylinder head–to–exhaust manifold gaskets, a front “donut” ring gasket at the spring-bolt joint, flange gaskets further down the system, and (on XT) turbo outlet and up-pipe gaskets. So an exhaust-gasket is relevant and fitted on this model.

These gaskets seal the joins between exhaust components so hot gases don’t escape. That keeps noise down, prevents fumes from sneaking into the cabin, helps the oxygen sensors read accurately, and maintains the correct flow for the catalytic converter and, on XT models, for turbo response. When a gasket fails, drivers might hear a ticking or chuffing on cold start, smell exhaust near the front of the car, or see sooty marks at a flange.

Exhaust gaskets aren’t generally a scheduled replacement item
