Chevrolet Silverado Performance Exhaust - aFe - Twisted Steel Up-Pipe - 01-04. A direct-fit up-pipe designed for GM 6.6L LB7 turbo-diesel trucks, this aFe Twisted Steel Up-Pipe replaces the factory header up-pipe with durable stainless construction and heavy-duty flex sections for longer service life.
Built for durability and improved flow characteristics, the Twisted Steel Up-Pipe is made from 2" mandrel-bent 304 stainless steel tubing with a 0.120" wall thickness. The design uses heavy-duty 2" flex tubing with an internal liner to control movement while maintaining airflow. High-quality 3/8" thick laser-cut flanges provide a full 360° sealing surface to reduce the chance of exhaust leaks. This unit fits 2001–2004 GM diesel trucks with the 6.6L V8 LB7 engine and is intended for enthusiasts seeking a robust replacement or upgrade to the OEM up-pipe.
