      Description

      High-Flow Turbo Efficiency. The PPE 3-Inch Down-Pipe is designed to enhance turbocharger performance by significantly increasing exhaust flow. Ideal for performance-driven diesel owners, this upgrade reduces backpressure and lowers exhaust gas temperatures (EGTs), delivering better throttle response and turbo efficiency on demanding workloads.

      Construction and Appearance. Constructed from 3-inch mandrel-bent stainless steel, the PPE down-pipe is built for durability and optimal airflow. The smooth, precision bends eliminate restrictions, and the corrosion-resistant finish ensures long-term reliability under high-heat and harsh driving conditions.

      Installation. Installation is moderately difficult and may require access to specialized tools or a lift. The direct bolt-on design fits factory mounting points without the need for custom modifications.

      Warranty. This product includes a limited lifetime warranty for added peace of mind.

      Application. This PPE 3-Inch Down-Pipe fits 2015 to 2016 6.6L Duramax Sierra 3500 HD.
