The Wehrli Custom Fabrication WCF100119 is a 3-inch turbo downpipe engineered specifically for 2001-2004 GM 6.6L LB7 Duramax diesel engines. This performance exhaust component is designed for use with OEM turbochargers or Wehrli's Stealth series drop-in turbo replacements, providing improved exhaust flow and reduced backpressure.

• High-temperature ceramic coating for durability and heat management
• Includes heat wrap for additional thermal protection

The high-temp coating and included heat wrap help manage exhaust temperatures while protecting surrounding components.
