High Flow Exhaust Manifold for Ram 2500/3500 6.7L Cummins Diesel 24V (2007.5-2018)

This high flow exhaust manifold is a direct OEM replacement for the factory exhaust manifold on 2007.5–2018 Dodge Ram 2500 and 3500 trucks with the 6.7L Cummins engine. It delivers significant exhaust flow improvements—test results showed a 72% increase in exhaust flow over the factory manifold—while solving the cracking, warping, and shrinkage problems that plague the OEM design. Built from high-silicon ductile iron with a fully divided pulse manifold design, it eliminates the failures that compromise factory performance.

Fitment

• 2007.5–2009 Dodge Ram 2500/3500 6.7L Cummins 24V
• 2010–2012 Dodge Ram 2500/3500 6.7L Cummins 24V
• 2013–2018 Dodge Ram 2500/3500 6.7L Cummins 24V

Product Details

• Material: High-silicon ductile iron construction designed to withstand extreme temperatures and vibration.
• Design: Fully divided pulse manifold with precision slip joints that allow the manifold to expand and contract, reducing cyclic thermal fatigue and increasing longevity.
• Turbo Flange: Factory T4i flange that bolts directly to stock HE351VE or HE300VG turbocharger with no modifications.
• Performance: Reduces exhaust gas temperatures (especially on the rear cylinders), improves turbo spool-up, and enhances throttle response.
• EGR Compatibility: Retains factory-style HE351VE turbo flange and EGR connections for full emissions compliance.
• Sensor Ports: Equipped with dual 1/8" NPT exhaust gas ports supplied for gauges or testing.
• Gaskets Included: Includes 6-port gaskets to ensure leak-free seal.
• Fitment Note: Does NOT fit 2013–2018 Cab & Chassis models (Ram 3500/4500/5500 Cab & Chassis). These trucks use a different manifold-to-exhaust routing and turbo position that is not compatible with this manifold.

Installation

This high flow exhaust manifold is a bolt-on replacement that requires removal of the factory manifold and mounting to your existing turbocharger. Professional installation is recommended to ensure proper torque, gasket sealing, and alignment.

Check local emissions regulations before purchase. Professional installation is recommended.
