Product Description

The MagnaFlow 5531447 California Grade Direct-Fit Manifold Catalytic Converter is engineered as a direct replacement for select 2006-2011 Subaru and Saab models equipped with the naturally aspirated 2.5L horizontally opposed four-cylinder engine. Designed to replicate the factory manifold converter assembly, it restores emissions performance while maintaining original exhaust flow and engine efficiency without requiring cutting or welding.

Constructed from corrosion-resistant 409 stainless steel with a ceramic catalyst substrate, the 5531447 features mandrel-bent tubing, precision laser-fusion welding, and durable 308 stainless steel MIG welds for long-lasting reliability. It meets California Air Resources Board (CARB) requirements under Executive Order D-193-175, making it legal for use in all 50 states on approved applications. Included gaskets and mounting hardware simplify installation and help ensure a leak-free seal.
