2017-2024 GM 6.6L Duramax Replacement Up-Pipe (Driver Side) for OEM Exhaust Manifold

PPE has taken OEM replacement to a new level. All PPE OEM Up-Pipes allow 53% greater flow than stock. PPE OEM Up-Pipes are a direct bolt-on to your factory manifolds. Unlike factory parts, PPE OEM Up-Pipe are manufactured from 11-gauge 304 stainless steel and includes our superior PPE 304 stainless steel, internally sleeved bellow that can take the abuse of high temperature and high pressures. NOTE: This product is intended as a replacement for the single up-pipe from the PPE High-Flow Up-Pipe Kit (SKU 116122000).
