BD Diesel Cast Exhaust Manifold - 07.5-12 Ram 2500/3500 6.7L Cummins
BD Diesel Cast Exhaust Manifold delivers heavy-duty pulse flow performance from high-silicon ductile iron for 2007.5-2012 Ram 2500 and 3500 trucks with 6.7L Cummins diesel engines. This manifold withstands extreme temperatures over 1600°F and heavy vibrations for reliable towing and daily driving in stock or modified setups. Precision engineering with slip joints prevents cracking while optimized exhaust runners drive faster turbo spool-up and power across the RPM range.
Key Features
- High-Silicon Ductile Iron: Cast design resists EGTs over 1600°F and diesel truck vibrations for long-term reliability in daily driving and towing.
- Pulse Flow Technology: Exhaust runner design enhances scavenging and turbo response for quicker boost buildup and horsepower gains throughout the RPM range.
- Precision Slip Joints: Flexible connections accommodate thermal expansion and contraction to minimize stress cracks and outlast factory manifolds.
- Advanced CFD Engineering: Computational fluid dynamics modeling ensures balanced exhaust flow and maximum performance in every condition.
- Bolt-On Compatibility: Direct replacement for OEM manifold on 6.7L Cummins engines with no cutting or modifications required.
Product Notes
- Replaces OEM manifolds prone to cracking from high heat cycles in Cummins trucks.
- Inspect turbo mounting and exhaust studs before installation for best results.
- Packaged to prevent damage during transit with protective inserts.
Installation Notes
- Professional installation recommended.
- Apply anti-seize to studs and torque to 18 ft-lbs in sequence using OEM pattern.
- Compatible with factory gaskets hardware and turbocharger setup.
