Experience improved performance and durability with the BD Diesel 01-16 Chevrolet Silverado/GMC Sierra 2500/3500 HD 6.6L Exhaust Manifold Kit, part number 1041459. Designed specifically for the 2001-2016 Duramax engines, these manifolds address common flow restrictions and enhance exhaust flow efficiency. The driver’s side manifold has been upgraded to eliminate flow restrictions present in earlier models, resulting in a 5% overall increase in exhaust flow on both manifolds. Crafted from high-silicon ductile iron, the manifolds feature castings that are 65% thicker than standard, providing superior resistance to warping and cracking under extreme conditions. This robust construction ensures long-term reliability in demanding heavy-duty applications. The kit includes all necessary fasteners and gaskets, making installation straightforward and reducing downtime. The predrilled pyrometer port on the driver’s side allows for easy temperature monitoring, an essential feature for tuning and maintenance. With high-temperature paint applied for corrosion resistance, these manifolds are engineered to withstand the intense heat generated by diesel exhaust gases while maintaining structural integrity. Whether upgrading for increased airflow or replacing worn-out components, these manifolds are a direct bolt-on solution designed to optimize turbocharger efficiency and overall engine performance.
Features:
- Heavy-duty 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 installation
- Complete kit includes gaskets and fasteners for a quick, drop-in installation
- Enhanced exhaust flow by 5% to improve turbocharger efficiency and engine response
