Description

PPE's High-Flow Manifold and Up-Pipe Kit is engineered to maximize flow, lower exhaust gas temperatures and speed up turbo spool on the early Duramax. This version adds a silver ceramic coating for better heat management and a clean under-hood look. The high-sil moly cast iron manifold pairs with internally sleeved 304 stainless up-pipes for increased inner diameter and flow.
