MagnaFlow specializes in superior catalytic converter and exhaust technology and has spent the past 30+ years earning its reputation as a global market leader. American engineered and manufactured, MagnaFlow Catalytic Converters combine efficient industrial design to produce a product that exceeds, rather than meets, the highest standards of product performance and efficiency in the industry.

MagnaFlow uses both Ceramic and Metallic substrates with different combinations of cell density and wall thickness to meet vehicle specific requirements. MagnaFlow Direct-Fit Catalytic Converters are designed for easy bolt-on installation for the Professional Installer. Each is designed to exact the original equipment specifications.
