Eastern Convertors 41170 Catalytic Converter - Rear

Direct-Fit Rear Catalytic Converter

Eastern Convertors DIRECT FIT 41170 is a federal/EPA direct-fit undercar catalytic converter built to OE dimensions for a precise replacement on select Subaru applications. It uses a standard catalyst design and a NANO substrate formulation to support efficient exhaust treatment while keeping fitment and installation straightforward.

Compatible with Subaru Outback, Forester, Crosstrek, Impreza, and XV Crosstrek rear applications, this converter is built for drivers replacing a worn or failed emissions component on the Subaru exhaust system. The DIRECT FIT line focuses on exact dimensional match and consistent production quality for a clean undercar installation.
