BD Diesel Exhaust Manifold Kit – 2001-2016 Chevrolet Silverado / GMC Sierra 2500/3500 HD 6.6L Duramax

The BD Diesel Exhaust Manifold Kit is a high-performance upgrade for the 2001-2016 Chevrolet Silverado and GMC Sierra 2500/3500 HD equipped with the 6.6L Duramax diesel engine. These upgraded manifolds eliminate the factory flow restriction on the driver’s side (2001-2006 models) and provide smoother, more efficient exhaust flow to the turbocharger.

Constructed from high-silicon ductile iron with 65% thicker castings than stock, they are highly resistant to warping and cracking under extreme heat and stress. Designed as a complete drop-in kit, it includes all necessary fasteners and gaskets for a straightforward installation. This kit improves turbo spool, reduces exhaust gas temperatures, and enhances overall engine efficiency and durability for towing, daily driving, or performance applications.

Key Features

  • Improved Exhaust Flow – Removes factory restriction on driver’s side manifold for better turbo response
  • High-Silicon Ductile Iron – 65% thicker castings for superior resistance to warping and cracking
  • Complete Drop-In Kit – Includes all fasteners and gaskets for easy installation
