      Description

      Turbo Efficiency with Maximum Flow. This 4-Inch Turbo Exhaust Pipe is designed to improve the performance of your 6.6L Duramax by increasing exhaust flow and reducing restrictions between the turbo and the rest of the system. The larger diameter allows hot gases to exit more freely, resulting in faster spool-up, better throttle response, and lower exhaust gas temperatures under load.

      Engineered for High-Heat and High-Boost Conditions. Constructed from thick-wall steel and precision mandrel-bent, this pipe is built to handle the thermal demands of heavy-duty diesel engines. Its raw finish is ideal for custom exhaust configurations, especially for builds that demand high-flow efficiency. Designed for long-term reliability, it’s a vital upgrade for performance or towing applications.

      Installation. This product installs using weld-on or clamp-on connections as part of a custom or aftermarket exhaust system. Professional installation is recommended.

      Application. This 4-Inch Turbo Exhaust Pipe is designed to fit 2017-2025 6.6L Duramax Sierra 3500 HD models.
