      Description

      High-Performance Downpipe. The AFE MACH Force-XP Turn Downpipe with 3-Bolt Flange is engineered to improve airflow and turbo response by replacing the restrictive OEM downpipe. This upgrade enhances engine performance and reduces exhaust gas temperatures for diesel trucks equipped with turbochargers.

      _x000D__x000D_

      Construction and Appearance. Made from mandrel-bent 3-inch 409 stainless steel tubing, the downpipe has a ceramic coating applied both inside and outside. This coating helps insulate heat, resist corrosion, and reduce under-hood temperatures, featuring a heat-resistant satin finish for durability and aesthetic appeal.

      _x000D__x000D_

      Installation. Installation is straightforward, requiring no drilling or modifications, as the downpipe mounts directly to factory locations using the included hardware. Factory oxygen sensors are retained for seamless integration.

      _x000D__x000D_

      Application. Designed specifically for 2015-2016 6.6L Duramax engines in the Sierra 3500 HD, this downpipe fits models equipped with a 3-bolt flanged downpipe.
