Product Overview

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.

All Federal catalytic converters meet EPA requirements. Federal Catalytic Converters are not legal for sale, installation or use on vehicles registered in the state of California.

All California State Catalytic converters are CARB compliant. Converters in this catalog are based on Executive Orders issued by the California Air Resource Board and must be used in accordance with this information. In California, it is illegal to select a catalytic converter for installation based solely on vehicle weight and engine size.

MagnaFlow universal spun catalytic converters utilize the revolutionary new catalyst technology. Using new manufacturing technology, they fabricate each converter body from a single CNC-formed and laser-welded tubular section, which is then spun into a round converter body shape. The MagnaFlow universal spun catalytic converters are literally manufactured around the catalyst, which is securely tucked inside and necks down to thicker gauge material at the inlet/outlet for maximum durability. They are available in different diameter inlets and outlets to match your specific exhaust system. Whether you need centered, offset, or angled converters, MagnaFlow universal spun catalytic converters will fit any application.
