Experience performance and durability with the enhanced Duramax exhaust manifolds, specifically designed for the 2001-2016 6.6L Duramax engines. The BD upgraded manifolds not only remove the flow restriction found on the 2001-2006 model driver’s side manifold, but they also increase overall flow on both manifolds by 5%! 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.
Features
- Cast iron construction with 65% thicker walls for increased toughness and resistance to cracking
- Predrilled pyrometer port on driver's side manifold for easy sensor install
- High temperature paint for corrosion protection
- 5% increase in flow to more efficiently transfer exhaust gases to the turbocharger
- Sold as a complete kit with gaskets and fasteners for easy install
