Maximize Your LB7 Duramax Performance with the AFE 48-34137 Twisted Steel Headers, Up-Pipes & Down-Pipe Kit

Unlock the full potential of your 2001-2004 LB7 Duramax with the AFE 48-34137 Twisted Steel Headers, Up-Pipes & Down-Pipe Kit. Engineered to deliver superior performance and durability, these headers are constructed from high-quality, ductile cast iron for long-lasting strength and resistance to cracking under extreme conditions. With a design that flows 6% better than factory exhaust manifolds, this upgrade ensures improved exhaust flow, increased horsepower, and enhanced overall engine efficiency.

The headers are pre-drilled and tapped for 1/8" NPT ports, making it easy to integrate exhaust gas temperature (EGT) sensors for precise monitoring of your engine’s performance. Additionally, the elimination of the restrictive pinch found on the factory driver-side manifold allows for even greater airflow, resulting in quicker turbo spool and improved throttle response.

This comprehensive kit is designed to provide your Duramax with a significant boost in performance, making it the ideal choice for those looking to upgrade their exhaust system and get the most out of their truck.
