AAM Competition‘s 370Z Resonated 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 catalytic converters offer a high quality metallic catalytic element that flows a higher volume of air in contrast to the original equipment, resulting in increased performance.
The leading benefit of the 370Z Resonated High Flow Cats is that they significantly reduce back pressure vs. the factory cats, while increasing your overall exhaust volume, creating a deeper and smoother tone, without significantly increase drone.  This is the prefect upgrade for enthusiast looking to optimize exhaust flow performance by replacing the restrictive factory cats without adding adding to much more exhaust volume.  This is the quietest option that we offer in regards to replacing the factory cats.  All while enjoying up to an average extra 8 to 16hp depending on the rest of your exhaust setup!
