Description

Wehrli 01-04 Chevrolet 6.6L Duramax LB7 2in Stainless Pass. Side Up Pipe w/Gaskets (Single Turbo)

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. This up pipe is built to clear a conventional downpipe behind the engine in single turbo applications with the mounting location in the valley of the engine like stock. This product may also be used with a twin / compound turbo setup, but we recommend upgrading to our Twin Turbo up pipe WCF100648 in those installations for superior performance. - - Includes Up Pipe Gaskets - - Replaces GM 97302261 - - NOTE: This up pipe will ONLY fit with OEM exhaust manifold or WCFab Duramax Billet Exhaust Manifolds (WCF100363). It is NOT designed for use with aftermarket exhaust manifolds that move the exhaust outlet location further away from the cylinder head. - - Designed for use with WCFab downpipe. OEM and another aftermarket downpipes may require additional modifications
