aFe 2001-2004 GM Duramax Diesel Trucks 6.6 LB7 3" Turbo Downpipe-Black

Upgrade the performance of your 2001-2004 LB7 GM diesel with the aFe ATLAS 3" Turbo Down-pipe. Designed for improved flow and optimal fitment, this down-pipe is a perfect upgrade to your OE down-pipe, utilizing factory mounting locations for a true bolt-on performance.

Enhanced Flow and Response: Constructed from 3" mandrel bent steel tubing, the ATLAS Turbo Down-pipe offers smoother transition bends to minimize turbulence and deliver quicker throttle response. The larger tube diameter and improved airflow between your OE turbo and exhaust system help reduce exhaust gas temperatures (EGT's) and achieve faster turbo spool times.

Leak-Free Seal: The CNC machined heavy-duty inlet flange and quality V-band flange ensure a complete 360-degree sealing surface at the turbo housing and exhaust system. This guarantees an OE-style fitment and eliminates any leaks that could compromise performance.

Durable Finish and Insulation: The down-pipe is coated with a sleek black finish that not only adds visual appeal but also provides durability and resistance against corrosion. Additionally, the down-pipe is wrapped in high-temperature thermal header tape, offering better insulation. This insulation helps to reduce EGT's and under-hood temperatures, further enhancing performance and reliability.

Emissions Compliance Information: Please note that some or all of the applications listed for this product are 50-state exempt. For specific details, please refer to CARB EO# D-550-48.
