The GMC Sierra Performance Exhaust - Passenger Side - Wehrli - Stainless 2in Up Pipe Kit for the `11-`16 models is an exceptional enhancement for your truck’s exhaust system. Engineered for the 2011-2016 6.6L LML Duramax-equipped Chevrolet Silverado or GMC Sierra 2500/3500 HD trucks, this high-performance kit offers robustness and reliability by replacing the fragile OEM up pipe.

Constructed with 11-gauge stainless steel, the Wehrli up pipe kit not only enhances durability but also improves exhaust flow for increased turbo spool-up and reduced exhaust gas temperatures (EGT), making it an excellent choice for heavy-duty towing and performance upgrades. It is built to integrate seamlessly with OEM style exhaust manifolds and the WCFab Billet Exhaust Manifold (Part Number WCF100363), fully optimizing your truck’s power without requiring additional tuning or modifications.
