ATS Pulse Flow Exhaust Manifolds for 2001-2004 6.6L Duramax

Enhance the performance and reliability of your 6.6L Duramax with ATS Pulse Flow Exhaust Manifolds, designed to significantly reduce restriction compared to stock manifolds and up-pipes. These manifolds deliver a 26% increase in airflow, ensuring greater engine efficiency and faster turbocharger spool-up.

Crafted from High Silicon Molybdenum (HSM), these manifolds are built to withstand extreme heat cycles without cracking, warping, or fatigue, making them a durable, long-lasting solution for high-performance diesel engines. The manifold design features progressively expanding exhaust ports to maintain thermal velocity, driving exhaust gases quickly and efficiently into the turbocharger for maximum power.

Thanks to the heat-retaining properties of the HSM material, hot exhaust gases expand as they exit the engine and enter the turbocharger, providing faster spool-up and improved turbine performance. Unlike headers, which can slow down gas velocity and reduce turbo efficiency, the ATS Pulse Flow Manifolds keep gases hotter and faster, giving you the edge in performance.

Key Features:

• 26% increase in airflow over stock manifolds for improved performance
• Cast from durable High Silicon Molybdenum (HSM) for long-lasting heat resistance
• Optimized exhaust flow for faster turbocharger spool-up and increased power
• Retains heat to maintain exhaust gas expansion for more turbine action
• Prevents cracking, warping, and fatigue over extended heat cycles
• Improves engine efficiency and turbo performance over stock components

Upgrade to ATS Pulse Flow Exhaust Manifolds and unlock the full potential of your Duramax engine with better airflow, faster turbo spool, and long-term reliability
