BDD Exhaust Manifolds

Experience performance and durability with the enhanced Duramax exhaust manifolds, specifically designed for the 2001-2016 6.6L Duramax engines. The BD upgraded manifolds remove the flow restriction found on the 2001-2006 model driver's side manifold and efficiently transfer exhaust gases to the turbocharger. Crafted with precision, the BD manifolds feature robust, 65% thicker designed castings constructed from high-silicon ductile iron to combat warping and cracking. Designed to be a one-stop drop-in kit, including all fasteners and gaskets needed to make installation quick.
