AAM Competition‘s 370Z High Flow Catalytic Converters are designed to increase total engine power output and performance, while maintaining environmentally friendly exhaust emissions characteristics like the factory units. The OE catalyzers are primarily designed for air purification and use an extremely dense catalytic converter core, increasing exhaust resistance. The AAM Competition catalytic converters offer a catalytic element that flows a higher volume of air in contrast to the original equipment, resulting in increased performance.
