Product description
Maximum Durability: BD Upgraded Duramax Exhaust Manifolds
Upgrade your 2001-2016 6.6L Duramax with a manifold set designed to outperform and outlast factory hardware. Whether you're looking to fix a cracked driver’s side manifold or looking for a performance edge, BD Diesel delivers a robust, high-flow solution.
Engineered for Extreme Strength
Factory manifolds are prone to warping and cracking under the high exhaust gas temperatures (EGTs) common in diesel engines. BD has reinforced these critical components:
65% Thicker Walls: Massive increase in casting thickness provides superior toughness and resistance to heat-induced cracking.
High-Silicon Ductile Iron: Constructed from premium materials specifically chosen to combat warping during heavy towing or high-performance driving.
Corrosion Protection: Finished in high-temperature paint to ensure they look good and stay protected against the elements for years to come.
Improved Flow & Performance
BD didn't just make them stronger; they made them faster:
5% Flow Increase: Optimized internal geometry transfers exhaust gases to the turbocharger more efficiently.
Fixes OEM Restrictions: Specifically replaces the highly restrictive driver’s side manifold found on 2001-2006 models, unlocking hidden performance.
Integrated EGT Port: Features a pre-drilled and tapped pyrometer port on the driver’s side, making sensor installation for your gauges a breeze.
