Diamond Eye TURBO-DIRECT 3in AL CHEVY/GMC LLY LBZ LLM DURAMAX 04-10

This Diamond Eye TURBO-DIRECT downpipe is a 3-inch aluminized steel pipe designed to connect directly to the turbocharger on select Chevrolet and GMC Duramax diesel trucks from 2004 to 2010. It's built to replace the factory downpipe, which can sometimes be a restriction, especially on modified trucks. By using a larger diameter and a smoother, mandrel-bent design, this pipe helps the turbocharger expel exhaust gases more efficiently.

Diamond Eye Manufacturing uses CNC mandrel bending to create these pipes, ensuring consistent diameter and smooth bends throughout the entire length. This process helps maintain exhaust gas velocity while reducing turbulence, which can lead to improved turbo spool-up and better overall exhaust flow. The aluminized steel construction offers a good balance of durability and corrosion resistance for everyday use.

This downpipe is designed as a direct replacement for models equipped with the LLY, LBZ, and LMM Duramax engines, fitting a range of 2500 and 3500 series trucks. It's a popular choice for owners looking to get a bit more out of their exhaust system without a full turbo-back replacement.
