The PPE Up-Pipe for 2017-2024 GM 6.6L Duramax is a direct bolt-on replacement exhaust pipe for the passenger side that significantly improves exhaust flow and reduces back-pressure compared to stock. Made from 11-gauge, 304 stainless steel with a 2.00 in. outer diameter and heavy-wall construction, the pipe’s free-flowing interior bellow enhances turbo response and lowers exhaust temperatures — ideal for trucks seeking more responsive performance and reliability under load.
