Description

The Wehrli 3-inch downpipe is a bolt-on upgrade designed for 2001-2004 GM 6.6L Duramax LB7 diesel engines. It replaces the restrictive factory turbocharger down-pipe to provide more efficient airflow. This downpipe comes with a high-temperature ceramic coating and is heat-wrapped, making it compatible with both standard and California-style exhaust flanges.
