Fix Common 24V Cummins Exhaust Manifold Failures
If your 1998.5-2002 Dodge Ram 2500 or 3500 equipped with the legendary 5.9L 24-Valve Cummins is suffering from exhaust leaks, ticking noises, broken manifold bolts, warped runners, or a cracked factory manifold, this Heavy Duty Ductile Iron Exhaust Manifold is the long-term solution.
Factory Cummins manifolds are known for cracking under repeated heat cycles. As exhaust temperatures increase during towing, daily driving, performance tuning, or larger turbocharger upgrades, the OEM manifold can warp and leak, resulting in reduced turbo efficiency, slower spool-up, higher EGTs, and loss of power.
Designed specifically for the 1998.5-2002 Dodge Ram 5.9L Cummins platform, this upgraded ductile iron manifold provides superior durability, improved exhaust flow, and long-lasting reliability.
Why Upgrade Your Factory Cummins Exhaust Manifold?
A cracked or leaking exhaust manifold can cause:
- Exhaust ticking noises
- Reduced turbocharger response
- Increased exhaust gas temperatures (EGTs)
- Exhaust soot buildup around manifold ports
- Lower towing performance
- Reduced fuel efficiency
- Broken manifold bolts and hardware
Replacing a failing factory manifold restores proper exhaust flow and turbocharger efficiency while helping protect your engine from unnecessary heat stress.
Heavy-Duty Ductile Iron Construction
Unlike factory cast iron manifolds that are prone to cracking, this manifold is manufactured from high-strength ductile iron designed to withstand:
- Extreme towing temperatures
- Performance tuning applications
- Daily driving heat cycles
- High boost pressure environments
- Long-term thermal expansion and contraction
The reinforced casting helps eliminate the common cracking issues associated with OEM Cummins manifolds.
Improved Exhaust Flow & Turbo Performance
The internal runner design promotes smoother exhaust gas evacuation from the cylinder head to the turbocharger.
Benefits include:
- Faster turbo spool-up
- Improved throttle response
- Reduced exhaust restriction
- More efficient exhaust gas flow
- Better towing performance
- Improved support for aftermarket turbochargers
Whether you're running a stock HX35 turbo or a larger aftermarket setup, proper exhaust flow starts at the manifold.
Perfect For Stock & Performance Applications
This manifold is ideal for:
- Stock replacement repairs
- Daily driven trucks
- Tow rigs
- Work trucks
- Mild performance builds
- Upgraded turbocharger setups
- High-mileage Cummins restorations
Direct Bolt-On Installation
Designed as a direct replacement for the factory manifold.
Fits factory:
- Cylinder head
- Turbocharger location
- Exhaust components
No fabrication required.
