First Gen Cummins Exhaust Manifold | 12 Valve Cummins Performance Upgrade

Fits 1988–1993 Dodge Ram 5.9L First Gen Cummins

CARB Exempt – Legal for Installation and Street Use in California

The DPS First Gen Cummins Exhaust Manifold is a high-performance, direct bolt-on replacement for 1988–1993 5.9L 12V Cummins engines. Designed specifically for the 1st Gen rectangular port head, this manifold flows significantly better than stock, reduces rear-cylinder EGTs, and provides maximum durability with 3-piece expansion joints.

Top Features & Benefits:

  • Flows 23% more than OEM 1st Gen Cummins manifold
  • CFD tested and balanced for smooth exhaust velocity and better turbo spool
  • Includes 6 exhaust manifold gaskets
  • Three drilled and tapped ports for pyrometer and pressure fittings—including bottom port
  • Manufactured from nickel-laced ductile iron for extreme heat resistance
  • Black high-temp coating for corrosion protection
  • Ships pressed together and ready to install
  • Direct replacement for OEM parts: 04429349 and 04883352

Why Choose DPS Over Stainless Manifolds?

Single-piece stainless manifolds expand and contract up to 2x more than our ductile iron manifold. That extra movement stresses your head, gaskets, and bolts—leading to leaks or failures. The DPS 3-piece design allows natural thermal flexing without damage.

Purpose-Built Mold for 12V Rectangular Ports

Most competitors machine their 24V round-port castings to fit 12V heads. This creates smaller, restricted ports and poor airflow transitions. The DPS First Gen manifold uses a dedicated rectangular port mold—engineered specifically for 12V flow performance. It’s more expensive to produce, but gives you better power, smoother EGTs, and optimal fitment.

OEM Replacement Part Numbers:

  • 04429349
  • 04883352
  • 03911349
  • 3920598
  • 4638814
  • 3613547
  • 4429547
  • 101263

Still the best-priced 1st Gen Cummins exhaust manifold on the market—why settle for less?

    This Manifold has done what is says. Turned up 12V 362 turbo injectors and AFC mods on a 5 Speed. Lowered EGT by 75 degrees and spools at around 1550 Rpms about 200 Rpms faster than the stock Manifold. Easy to install Nice coating and welded between flanges all in a 3 piece. Sure will last for a long time. Truck runs smoother and doesn't feel laggy at all had to remove some pre boost to tone her down a bit. Thanks DPS just what I needed .

  • Perfect!

    sounds like new truck at 305k...mine shrank badly on ends, does make my 66mm turbo sing 2-300 rpms earlier and the top end it loud n pulls hard but also has light pedal power too
