ATS 204-950-2326 Pulse Flow Manifold Gaskets Studs for 07.5-18 Ram 6.7L Cummins

Vehicle Fitment

• 2007.5-2018 Ram 2500 (6.7L Cummins)
• 2007.5-2018 Ram 3500 (6.7L Cummins)

Fitment Notes

• Designed for the 2-piece Holset 351VE turbo flange configuration
• This is the full kit variant, including multi-layer gaskets, EGR gaskets, and premium studs - ATS also offers this manifold as a bare unit (PN 204-910-2326) or with gaskets only, no studs (PN 204-927-2326)
• A closely related kit in this manifold family is documented as not compatible with Cab & Chassis trucks; confirm Cab & Chassis compatibility with ATS before ordering if applicable to your build

Features

• Patented bell mouth design reduces backpressure and increases exhaust gas flow
• D3 High Silica Molybdenum (HSM) cast iron construction resists cracking that affects stock gray iron manifolds
• Patented ball flange design for a more reliable, long-term seal
• Lowers EGTs through improved exhaust flow characteristics
• 2-piece design matches factory Holset turbo flange for a proper fit
• Multi-layer premium manifold gaskets included for reliable sealing
• Includes front and rear EGR gasket provisions
• Premium ATS Black Oxide studs made from 12.9-grade steel, stronger than stainless
• Studs rated over 185,000 psi tensile strength, torque to 40 ft-lbs
• Backed by nearly three decades of ATS Pulse Flow manifold development, dating to the original 1995 design

Product Description

ATS built the first Pulse Flow manifold back in 1995, and this 2007.5-2018 6.7L Cummins version carries that development forward with a patented bell mouth and ball flange design engineered to reduce backpressure and move exhaust gas more efficiently than the factory manifold. The result is lower EGTs and a more consistent flow path into the Holset turbo, both of which matter for engines that see regular towing or performance use.

Where the factory manifold is prone to cracking under repeated heat cycling, ATS casts this one from D3 High Silica Molybdenum iron, a material chosen specifically to resist the thermal stress that causes stock gray iron manifolds to fail over time. This particular kit (204-950-2326) is the complete package - it includes multi-layer premium gaskets, both EGR gaskets, and a full set of ATS's premium black oxide studs, so there's no need to source separate hardware or gaskets before installation.

This is a solid fit for 6.7L Cummins owners who've had a factory manifold crack or leak, or who simply want a more durable, better-flowing replacement before it becomes a problem. The included 12.9-grade studs, rated well beyond stock strength, are built to hold up under the same heat cycling that does in factory hardware over time.
