    WCFab's 2017-2025 L5P Duramax Billet Exhaust Manifolds replace the restrictive factory cast parts with high-strength, TIG-welded high-flow billet steel components. These manifolds are exhaust port gasket matched and internally divided for optimal flow with OEM or ported cylinder heads. Outlet locations allow full compatibility with OEM style up pipes and are designed to be paired with WCFab's 2" Stainless High-Flow Up Pipes (sold separately) for optimized performance. Fully compatible with vehicle emissions system, these L5P Manifolds include the necessary sensor port and EGR riser flange. Includes new gaskets, ARP 12PT fasteners, and assembly lube for easy install (up pipe fastener kits sold separately). Finished in Black Ceramic Coat rated for 1800 deg F.
