Replace the lightweight 16G, leak-prone passenger side OEM up pipe in your 2001-2004 6.6L LB7 Duramax with this heavy-duty 11 gauge 2" Stainless up pipe from WCFab. Our HD Stainless Bellow that will not crack and leak like OEM. Larger diameter and better flow than stock helps to increase Turbo spool up and decrease EGTs.
