Parts for your 2019 Toyota Prius-Exhaust gasket

2019 Toyota Prius exhaust gasket — what it is and when to replace it

Referencing technical sources, an exhaust gasket is indeed used on the 2019 Toyota Prius (ZVW50/51 series, 2ZR-FXE engine). Toyota’s Service Information (TIS) Repair Manual sections covering “Exhaust Pipe” and “Manifold with Catalytic Converter” specify gaskets and torque procedures at the manifold-to-cylinder-head joint and the pipe flanges. The Toyota Electronic Parts Catalog (EPC) for the ZVW50-series lists multiple exhaust gaskets by part name, including “Gasket, Exhaust Manifold” and “Gasket, Exhaust Pipe” for the joints between the manifold/catalyst, front pipe and rear muffler. Aftermarket technical guides (e.g., Haynes/Chilton covering Prius through 2019) also show replacement of these gaskets whenever the exhaust is separated. So, yes—this Prius uses exhaust gaskets at key joints and they’re service items when disturbed or leaking.

On a 2019 Toyota Prius, the exhaust gasket’s job is to seal the joins where hot exhaust gases pass from the engine to the catalytic converter and through the rest of the system. At the cylinder head there’s a multi-layer metal manifold gasket
