    MagnaFlow Catalytic Converter

    MagnaFlow Catalytic Converter

    The MagnaFlow Catalytic Converter transforms exhaust to harmless gas and boosts airflow. This cat was designed for excellent exhaust flow and clean emissions. It contributes to a clean environment and improves the performance as well as the sound of your application.

     Long lasting stainless steel

    Long lasting stainless steel

    This cat is made from heavy-gauge stainless steel for strength and corrosion resistance. Such an emission control device is expected to last the life of the vehicle.

    Efficient exhaust conversion

    Efficient exhaust conversion

    The converter contains two large ceramic honeycombed catalysts. Their large surface and a detailed coating process allow the exhaust to flow easily. MF innovative technology allows each catalyst to oxidize and reduce harmful emissions.

    Smooth exhaust flow

    Smooth exhaust flow

    Ribbing exists on two levels for your MagnaFlow Catalytic Converter. First, a ribbed body encases the ceramic catalyst to reduce expansion and distortion from the heat of normal operations. The ribs hold the ceramic catalysts in proper alignment. Second, the outer ribbed shield offers a final layer of protection against heat damage. It also reinforces the structural stability of the converter.

    Keeps catalyst together

    Keeps catalyst together

    The heavy-gauge stainless steel inner converter body that encases the ceramic catalysts is seam welded to the outer stainless steel heat shield. This kind of welding forms a strong bond between the converter's components and prevents them from becoming loose or shifting.

    Leek-free quality

    Leek-free quality

    There's a 1/2 inches lap joint where the neck and body of the cat overlap. The joint preempts the neck from extending into the body, where it could hinder exhaust flow. It also prevents leakage.

    Professional installation recommended

    Professional installation recommended

    The MagnaFlow Catalytic Converter is a universal-fit design. As such, you should expect some modifications such as welding, cutting, fabrication, and bending to ensure a perfect fitment. For these reasons, professional installation is highly recommended.

    Is your cat working?

    Is your cat working?

    Oxygen sensors are generally placed in front of and behind the cat. On some applications, one is plugged on the cat itself. Their role is to gauge the performance of your cat to ensure that it works great.

    49-State EPA approved

    49-State EPA approved

    This cat is 49-State Environment Protection Agency (EPA) approved. This means that it will get you through smog compliance in Canada and all states except California.

    Limited Lifetime Warranty

    Limited Lifetime Warranty

    When you purchase this MagnaFlow Catalytic Converter, your mind is eased by the fact that it is warranted against blowouts and defects in material and workmanship for LIFE.

    Made in the USA

    Made in the USA

    Made of high-quality materials in the USA, your cat has also benefited from refined manufacturing techniques. Your money funds American businesses, helps them to remain competitive and stops them from relocating to cheaper markets, keeping jobs in America.
