Features

  • Thick-wall casting resists high-heat cracking for long-term durability
  • Two-piece slip joint reduces stress from heat cycles to prevent failure
  • Divided pulse design improves exhaust flow to better spool and power the turbo
  • Pre-drilled EGT port makes aftermarket gauge installs simple
  • Direct stock replacement with full EGR compatibility for easy fitment
  • Includes all hardware for a hassle-free installation

About This Product

Cummins inline-6 engines are notorious for cracking their long, one-piece cast-iron manifolds, a problem that still affects many RAM trucks. BD Diesel’s exhaust manifold solves this with a thick-wall casting and slip-joint center section, allowing natural expansion and contraction to greatly reduce the risk of cracks.

Its divided Pulse Manifold design optimizes exhaust flow by harnessing the engine’s natural exhaust pulses for smoother operation and drivability. Fully emissions-compliant, the manifold also comes pre-drilled with an EGT probe port for easy monitoring.

Whether your truck is stock or modified, this is the perfect upgrade for reliability and durability. Available as a standalone manifold (PN:1045969) or as a complete installation kit including new bolts, spacers, and gaskets.

EXHAUST MANIFOLD KIT RAM 2500/3500 PICKUP 6.7L CUMMINS 2019-2024

What problem does this exhaust manifold solve?

The factory exhaust manifold on 2019–2024 6.7L Cummins engines is known to crack over time due to heat and expansion. This upgraded manifold is designed to handle extreme temperatures, reduce stress, and prevent cracking caused by thermal cycling.

What vehicles does this exhaust manifold fit?

This manifold fits 2019–2024 RAM 2500 and 3500 pickups, as well as RAM 3500, 4500, and 5500 Cab & Chassis models equipped with the 6.7L Cummins diesel engine. Be sure to select the correct pickup or cab & chassis version when ordering.

Is this manifold compatible with my stock emissions equipment?

Yes. This is a fully stock-compatible, drop-in replacement that works with all factory emissions components, including EGR systems.

What is a slip-joint design and why does it matter?

The two-piece slip-joint design allows the manifold to expand and contract with heat instead of cracking. This greatly improves durability compared to one-piece factory manifolds.

What does the divided pulse manifold design do?

The divided pulse design separates exhaust flow from the front and rear cylinders, helping better manage exhaust pulses. This can improve turbo response and overall efficiency compared to a standard open manifold.

Does this manifold include an EGT probe port?

Yes. The manifold comes pre-drilled for an Exhaust Gas Temperature (EGT) probe, making it easy to install aftermarket gauges.

What’s the difference between the “manifold only” kit and the “complete” kit?

Manifold only kits include the exhaust manifold and studs for turbo and EGR mounting. Complete kits include the manifold plus all required bolts, spacers, and gaskets for installation.

Is this a good upgrade if I’m replacing or upgrading my turbo?

Absolutely. This manifold is an excellent upgrade when replacing a failed turbo or installing a performance turbo, helping ensure long-term reliability and proper exhaust flow.

How long does installation take?

Professional installation typically takes about 7.5 hours, depending on the vehicle and shop experience.

Is this manifold suitable for towing or work trucks?

Yes. It’s designed specifically with towing, hauling, and work applications in mind, offering improved durability under sustained load and high exhaust temperatures.

What warranty is included?

This exhaust manifold is backed by a 36-month / 75,000-mile parts warranty.
