Ceramic core- The precious metal catalyst is bounded to an extruded ceramic honeycomb substrate. The ceramic has hundreds of flow channels that allow the exhaust gasses to come in contact with a maximum amount of surface area where the catalyst reaction takes place. The catalyst must come in direct contact with the exhaust gasses for the reaction to take place.
Metallic core- MagnaFlow Performance Exhaust has spun body catalytic converters utilizing the revolutionary new metallic catalyst technology. Using new manufacturing technology, Magnaflow fabricates each converter body from single CNC-formed and laster welded tubular section, which is then spun into a round converter body shape. Each converter is literally manufactured around the metallic substrate catalyst, which is securely tucked inside, and necks down to thicker gauge material at the inlet/outlet for maximum durability. The catalyst is a spirally wound ultra thin metallic foil.
