Description
Stock rubber compliance fittings on Evolution Big Twins are prone to cracking and leaking, compromising both performance and reliability. The S&S Cycle Manifold Conversion eliminates these weak points by replacing them with a rigid-mount system that maintains consistent intake geometry and reduces vibration-induced wear. If you’re running an 80″ Evolution engine and want a solid, leak-free manifold setup that will outlast the stock components, this kit delivers the durability and precision you need.
