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.
