Fitment

Please Note: MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter, part 5421159 (stored MPN mag5421159; legacy title 'MagnaFlow 08-09 Subaru Impreza 2.5L Direct Fit Converter', kept verbatim). FLAG: the stored copy application line says 2008-2009 Subaru Impreza 2.5L and 2009 Subaru Legacy 2.5L, while the stored fitment list (5 entries) names Impreza 2.5 GT / WRX and Legacy GT trims - both kept exactly as stored. CARB EO D-193-135 is from the stored listing attributes. Mapped to Master Sheet type Catalytic Converters under Leo's 2026-11-10 type ruling (Engine / Exhausts); taxonomy category set to Motor Vehicle Exhaust (gid://shopify/TaxonomyCategory/vp-1-4-8), and shopify.item-condition = New and shopify.manufacturer-type = Aftermarket were accepted on that category. Notes-only: no fitment bucket written.
