AAM Competition 370Z 2.5" High Flow Cats


AAM Competitionā€˜s Z34 High Flow Catalytic Convertors 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 action using an extremely high cel count in the catalytic element, increasing exhaust resistance. The AAM Competition catalytic convertors offer a interior catalytic element that flows a higher volume of air in contrast to the original equipment, resulting in increased performance.

Constructed of 100% T304 grade stainless steel, mandrel bent piping and hand assembled in our US facility, each set of AAM Competition High Flow Catalytic Converters offer superior finish quality as well as perfect fitment for your Z34 370Z. Fits all 2009+ Z34 370z and includes gaskets and hardware for easy installation.
