Wehrli 01-16 Chevrolet 6.6L Duramax 2in Stainless Driver Side Up Pipe w/Gaskets (Single/Twin Turbo)
Eliminate exhaust leaks and improve exhaust flow on your 2001–2016 Chevrolet Duramax diesel with the Wehrli Custom Fabrication 2-inch Stainless Driver Side Up Pipe. Constructed from premium 304 stainless steel, this up pipe is a significant upgrade over the factory cast iron unit that is notorious for cracking and leaking at the flex joint. The stainless steel construction resists corrosion and withstands extreme exhaust temperatures for long-lasting durability.
Compatible with single and twin turbo configurations, this up pipe works across the entire 2001–2016 Duramax lineup including LB7, LLY, LBZ, LMM, and LML engines. All necessary gaskets are included for a complete, leak-free installation. A foundational upgrade for any Duramax diesel performance build or preventive maintenance.
Fits: 2001–2016 Chevrolet 6.6L Duramax (LB7, LLY, LBZ, LMM, LML) — Single & Twin Turbo
