Show original supplier description
The Skunk2 NC Alpha Series Header is engineered to enhance the performance of your 2006-2013 Mazda Miata MX-5. Crafted from durable T-304 stainless steel, this header utilizes an equal-length, tri-Y design with sequentially paired, stepped primaries. This advanced configuration is developed to optimize exhaust flow, leading to significant gains in both horsepower and torque across the entire powerband. Drawing from Skunk2's extensive racing experience and sophisticated computerized modeling, the Alpha Header focuses on maximizing exhaust gas velocity. By employing the smallest practical primary tube diameters, it ensures high mid-range power and improved throttle response without sacrificing top-end performance. The design culminates in a 2.5-inch outlet collector, designed for seamless integration with other exhaust components. The construction ensures longevity and resistance to corrosion, making it a robust upgrade for performance-oriented Miata owners.
