DESCRIPTION

Vehicle Fitment

This 4" or 5" Downpipe-Back Race Exhaust System is engineered for 2001-2007 Chevrolet Silverado and GMC Sierra 2500/3500HD trucks with the 6.6L Duramax LB7, LLY, and LBZ engines. It does not fit Cab & Chassis trucks.


Performance and Application

By removing both the catalytic converter and DPF filter, this race exhaust system significantly improves exhaust flow. As a result, you will experience noticeable gains in both fuel efficiency and power output. The larger diameter options of 4" or 5" stainless steel piping further optimize airflow.

It also reduces exhaust gas temperatures and enhancing overall engine performance. Whether you are involved in off-road racing or competitive use, this system is designed to meet the needs of demanding applications.


Key Features

This downpipe-back exhaust system provides several key advantages for Duramax owners looking for improved performance:

  • Available in 4" or 5" stainless steel for enhanced durability
  • Downpipe-back design for maximum exhaust flow
  • OE-style hangers ensure secure and straightforward installation
  • Designed for off-road use, with no bungs included
  • Improves fuel efficiency by optimizing exhaust flow

If sound control is important to you, you have the option to add either a 4" or 5" muffler, depending on your preferences.


Installation Considerations

The Downpipe-Back Exhaust for Duramax LB7 LBZ is designed strictly for off-road use. It requires race tuning to unlock its full performance potential. The kit includes all necessary clamps and hardware for easy installation, though certain modifications may be needed depending on your truck’s configuration. For the best results, professional installation is recommended to ensure proper tuning and fitment.
