The Tomei exhaust manifold offers options for Equal Length, providing balanced performance, or Unequal Length for the classic Boxer sound, both delivering excellent results across the entire RPM range. The headers feature a larger 45mm diameter for enhanced power and sound, and they include an AF/O2 sensor bung for compatibility with OEM sensors. With over 5 pounds of weight savings compared to stock, the manifold’s lightweight, high-rigidity flange is crafted through a custom lost wax process. Its 4-2 collector design is optimized for flow and performance without any restrictive crush points, achieving an efficient and complex layout. Additionally, a Titan exhaust bandage is included to boost exhaust efficiency and protect against thermal damage. Extensive bench testing demonstrates improved performance across all RPM ranges, as shown in the engine dyno graph.
