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 Universal Catalytic Converters form the basic building blocks for a comprehensive line of direct-fit applications. The main benefit of the universal catalytic converter is that one unit may cover a wide variety of vehicle makes and models. Installing universal converters often requires the use of welding, cutting and tube bending equipment that is readily available to most professional installers.

Catalytic Converter Universal

Catalytic Converter Universal

Universal catalytic converters replace failing OEM converters on vehicles where a direct-fit replacement is unavailable or where a custom exhaust configuration requires a weld-in solution. Selecting the correct substrate size, inlet and outlet diameter, and cell density ensures proper fit and emissions performance. Popular Upgrades The most popular choices include high-flow universal catalytic converters with 400-cell metallic substrates for performance applications, standard-density 3-way catalytic converters for emissions-legal replacements, and high-temperature stainless steel bodies for durability under extreme exhaust heat. High-flow options from MagnaFlow and similar brands reduce backpressure while maintaining catalytic efficiency. What size universal catalytic converter do I need? Universal catalytic converter sizing is based on inlet and outlet pipe diameter, body length, and overall length. Common inlet sizes range from 1.75 to 3 inches.
