Wehrli 04.5-10 Chevrolet 6.6L LLY/LBZ/LMM Duramax 3in Down Pipe

This Wehrli down pipe kit includes the 3-inch diameter pipe itself, high-temperature ceramic coating for protection, heat wrap, and necessary clamps. It's designed to replace the restrictive, crushed factory down pipe on 2004.5 through 2010 Chevrolet and GMC trucks equipped with the 6.6L Duramax LLY, LBZ, or LMM engines.

By stepping up to a full 3-inch diameter, this pipe allows exhaust gases to exit the turbocharger more freely. This improved flow can lead to better turbo spool-up and a more efficient exhaust system overall. The high-temperature ceramic coating helps protect the pipe from corrosion and heat, contributing to its longevity. This down pipe is designed to work with either the factory turbocharger or a factory-style replacement turbo.

This part is a solid option for Duramax owners looking to improve their exhaust system's performance. Keep in mind that this down pipe is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and any additional hardware or procedures required.
