Description

Upgrade the Exhaust Manifolds and Up Pipes on your 2001-20024 LB7 Duramax to WCFab's Billet Exhaust Manifold & 2" Stainless Up Pipe Kit.

WCFab’s Billet Exhaust Manifolds replace the restrictive factory cast parts with high-strength, TIG-welded high-flow billet steel components designed to enhance exhaust flow characteristics, improving turbo spool up, lowering EGTs and increasing power and economy. These manifolds are exhaust port gasket matched and internally divided for optimal flow with OEM or ported cylinder heads. Includes new gaskets, ARP 12PT fasteners, and assembly lube for easy install (up pipe fastener kits sold separately). Finished in Black Ceramic Coat rated for 1800ºF.

WCFab's Up Pipe Kit replaces the lightweight 16G, leak-prone, 1 5/8" OEM up pipes with our heavy-duty 11 gauge 2" Stainless up pipe kit. HD Stainless Bellows that will not crack and leak like OEM. Increase Turbo spool-up and decrease EGTs. This kit is for use with single turbo applications and factory exhaust manifolds.

Manifold replaces the following GM Part Numbers: 12637647, 12624683, 97224587

Combines the following individual part numbers: WCF100363, WCF100590, WCF100240 (qty. 2). Saves $ and shipping costs vs. buying items individually.
