Rebuilding or upgrading your Duramax means you have some big decisions to make. One of those decisions is to determine which exhaust manifold you need for increased toughness and more features, while also making it easier to install. Plus you want improved performance over stock as we all know how the stock manifold's "pinch" robs you of power you deserve. Try BD Power's Exhaust Manifold Kit that has everything you need to make your Duramax flow exhaust at a 5% increase so you have less backflow and better turbo efficiency. Looking to add in a pyrometer? BD Power put in a redrilled pyrometer port on driver's side manifold for easy sensor install.
Heavy-Duty Duramax Exhaust Manifold Construction
Built for durability under extreme diesel engine conditions, BD Performance constructs these manifolds with 65% thicker castings compared to factory manifolds. The manifolds are manufactured from high-silicon ductile iron , a material specifically chosen for its strength and resistance to heat-related damage.
This upgraded construction helps prevent common Duramax exhaust manifold issues such as:
• Manifold warping from extreme heat cycles
• Cracking under heavy load or towing conditions
• Exhaust leaks caused by factory manifold distortion
Improved Exhaust Flow for 6.6L Duramax Engines
The optimized internal design increases exhaust flow by approximately 5% over stock Duramax manifolds . Improved exhaust flow can help reduce backpressure and support better turbocharger efficiency, making these manifolds a popular upgrade for both stock and performance Duramax trucks .
Complete Drop-In Installation Kit
These BD Duramax exhaust manifolds are designed as a direct bolt-on replacement for factory manifolds. The kit includes all necessary installation hardware to simplify the installation process.
• Heavy-duty BD Performance exhaust manifolds
• Required mounting fasteners
• Exhaust manifold gaskets
• Direct-fit design for factory locations
This complete kit makes installation straightforward for anyone replacing worn or cracked factory manifolds.
