The Magnaflow 60021 Universal 4" Offset Catalytic Converter is specially formulated to control diesel exhaust. Magnaflow Performance spun body catalytic converters utilize a revolutionary catalyst technology. Each converter body is fabricated from single CNC-formed and laser welded tubular section, which is then spun into a round converter body shape.
Each converter is then literally manufactured around the metallic catalyst, which is securely tucked inside, and necks down to thicker gauge material at the inlet and outlet for maximum durability. The catalyst is a spirally wound ultra thin metallic foil. Magnaflow spun body catalytic converters have no welds, and contain a metallic substrate for optimum CFM flow, and maximum durability.
