Vehicle Fitment

• 1998.5-2002 Dodge Ram 2500 (All Trims, 5.9L I6 24-Valve Cummins Diesel)
• 1998.5-2002 Dodge Ram 3500 (All Trims, 5.9L I6 24-Valve Cummins Diesel)

Fitment Notes

• Fits 1998.5 (Late 1998) 24-Valve Cummins only - does NOT fit Early 1998 12-Valve engines
• T-3 turbo flange only - not compatible with T-4 flanged turbo setups
• Non-wastegated design
• Exhaust manifold bolts not included - must be sourced separately
• Existing manifold gaskets may be reused if undamaged; replacement is recommended

Features

• 3-piece construction allows each section to expand and contract independently, eliminating cracking and warping
• Patented ball flange (bell mouth) design prevents exhaust port misalignment and gasket failure
• Cast from D3 High Silica Moly (HSM) iron - significantly more durable than OEM gray iron
• 30% larger internal diameter than stock for improved exhaust gas velocity and reduced back pressure
• Black high-temperature ceramic coating for lasting heat and corrosion resistance
• Pre-tapped for pyrometer (EGT) probe - no drilling required
• Pulse flow design spools the turbocharger faster with less exhaust back pressure
• California CARB EO Certified - EO# D-708

Product Description

The ATS Diesel 204-930-2218 PulseFlow 3-Piece Exhaust Manifold is a direct bolt-on upgrade for 1998.5-2002 Dodge Ram 2500/3500 trucks equipped with the 5.9L 24-Valve Cummins engine. Its 3-piece independently cast construction allows each section to flex through heat cycles without transferring stress, completely eliminating the cracking, warping, and exhaust leaks that are common on factory 24V manifolds.

Built from D3 High Silica Moly cast iron with a durable black ceramic finish, this manifold delivers 30% more airflow than stock and spools the T-3 turbo faster by keeping exhaust gas velocity high through the enlarged internal channels. Pre-tapped for an EGT probe and backed by a 5-year / 500,000-mile warranty, it's a reliable, high-performance upgrade for daily drivers, tow rigs, and mildly modified 24V Cummins builds running a T-3 flanged turbo.
