True dual header dual cat system opposed to the factory single cat design, Reduces backpressure by allowing each cat to flow ½ the engines exhaust opposed to all 6-cylinders of exhaust going through one single cat. Two Metallic Substrate catalytic converters with thinner cell walls (5.0 mil opposed to 6.5 mil of ceramic core), Provides a higher void to material ratio providing a decrease in frontal mass allowing greater flow through the catalytic converter resulting in less restriction and maximum airflow.
