ATS Diesel 204-943-2218 BigFoot PulseFlow 3-Pc Manifold T4 for 1998-2002 Dodge

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-4 turbo flange - requires an aftermarket T-4 flanged turbocharger; will NOT fit the stock T-3 flanged turbo
• Non-wastegated design
• Not legal for street use in California
• Exhaust manifold bolts not included - must be sourced separately
• Existing manifold gaskets may be reused if undamaged; replacement is recommended

Features

• 3-piece "BigFoot" construction - each section expands and contracts independently to prevent cracking and warping
• T-4 turbo flange supports a wide range of aftermarket turbocharger upgrades
• Patented ball flange (bell mouth) design reduces stress between manifold sections and eliminates gasket failure
• Cast from D3 High Silica Moly (HSM) iron - far more durable than OEM gray iron
• Larger internal diameter than stock for faster heat expulsion and improved exhaust gas velocity
• Black high-temperature ceramic coating for lasting heat and corrosion resistance
• Pre-tapped for pyrometer (EGT) probe - no drilling required
• Reduces turbo lag and improves spool-up with increased exhaust flow velocity

Product Description

The ATS Diesel 204-943-2218 BigFoot PulseFlow 3-Piece Exhaust Manifold is purpose-built for 1998.5-2002 Dodge Ram 2500/3500 trucks with the 5.9L 24-Valve Cummins that have been upgraded to a T-4 flanged turbocharger. The 3-piece BigFoot design eliminates the cracking and warping common on factory 24V manifolds by allowing each independently cast section to flex through heat cycles without stressing adjacent sections, while the enlarged internal diameter keeps exhaust gas velocity high for faster turbo spool and lower EGTs.

Built from D3 High Silica Moly cast iron with a durable black ceramic finish, this manifold is the ideal solution for 24V Cummins performance builds running aftermarket T-4 turbos. The patented ball flange design further reduces stress at the turbo connection, providing a leak-free seal under sustained high-heat conditions. Backed by ATS's 5-year / 500,000-mile warranty, it delivers the durability and performance that demanding tow rigs and modified builds require.
