The Full Speed Diesel Performance FS578 High Flow Manifold and Up Pipe Kit is engineered for the 2017–2025 GM Duramax L5P. The factory exhaust manifold and up pipe are a common failure point on these trucks — cracking, leaking, and costing you power and reliability. This complete kit replaces both with high flow components designed to improve exhaust scavenging, reduce EGTs, and restore confidence under load.
