Wehrli 04.5-10 Chevrolet 6.6L LLY/LBZ/LMM Duramax 3in Stainless Down Pipe
Improve exhaust efficiency and eliminate turbo-back pressure on your 2004.5–2010 Chevrolet Duramax diesel with the Wehrli Custom Fabrication 3-inch Stainless Down Pipe. Built from high-quality 304 stainless steel, this down pipe replaces the restrictive factory unit, allowing exhaust gases to flow more freely from the turbocharger outlet. The result is faster turbo spool, reduced exhaust backpressure, and improved diesel performance across the RPM range.
Compatible with LLY, LBZ, and LMM Duramax engines. Constructed for long-lasting durability in the harsh environment under a diesel truck. EPA Compliant, Non-CARB compliant. A key component for any serious Duramax exhaust or performance build.
Fits: 2004.5–2010 Chevrolet 6.6L LLY, LBZ, LMM Duramax
