BD Diesel 6.7L Cummins Exhaust Manifold Dodge 2007.5-2012 3500/4500/5500 Cab & Chassis

Fully divided pulse manifold made from high-silicon ductile iron and designed to withstand extreme temperatures and vibration. Great for both stock and performance trucks. Designed using modern technology utilizes pulse flow for quicker turbo spool and increased power. Precision slip joints allow the manifold to expand and contract, which reduces cyclic thermal fatigue and greatly increases manifold longevity.
