      Power and Turbo Efficiency. The Boosted Performance 3-Inch Downpipe replaces the restrictive factory pipe with a wide, mandrel-bent upgrade that enhances turbo response and exhaust velocity. It improves spool-up time while reducing EGTs for more consistent power delivery.

      Built for Boosted Demands. Made from TIG-welded stainless steel, this downpipe resists heat fatigue and corrosion. It offers a precise fit and a polished finish that stands up to extreme conditions under the hood, perfect for performance-minded builds.

      Installation. This item bolts directly in place of the factory downpipe with no custom fabrication required.

      Application. This Boosted Performance 3-Inch Downpipe fits 2011–2016 6.6L Duramax Sierra 2500 HD Models.
