Installation Notes and Tips

Verify vehicle fitment by year, make, and model before installation. This manifold is listed for 2010-2015 Toyota Prius, 2012-2018 Toyota Prius V, 2012-2015 Toyota Prius Plug-In, and 2011-2017 Lexus CT200h. Inspect the mating surfaces, fasteners, and exhaust connections before assembly, and replace any damaged sealing surfaces to help ensure a proper exhaust seal. Because this is an exhaust component, allow the system to cool fully before service.
