2017 Mitsubishi Lancer Exhaust Gasket — What It Does and When to Replace It

Technical sources confirm the 2017 Mitsubishi Lancer does use exhaust gaskets. The Mitsubishi Motors CF Lancer service manual and ASA parts catalogue list a cylinder head–to–exhaust manifold gasket plus a spring-bolt “donut” gasket at the manifold/front pipe joint, with additional flange gaskets further down the system. Major aftermarket catalogues (e.g., Fel‑Pro and Mahle) also catalogue manifold and flange gaskets for the 2017 Lancer 2.0/2.4. So yes—exhaust gaskets are absolutely relevant on this model.

On the 2017 Lancer, the exhaust gasket’s job is straightforward but critical: it seals the hot gas path so exhaust only goes where it should—through the cat and mufflers—keeping noise down, power and economy up, and fumes out of the cabin. Up top, a multi‑layer steel (MLS) manifold gasket seals the cylinder head to the manifold. Downstream, a compressible “donut” gasket and various flange gaskets seal the joints that let the system flex with heat and movement.

There’s no fixed service interval for exhaust gaskets
