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.
