BD Replacement Exhaust Manifold – T4 / T6 Flange Options

Replacement manifolds with larger T4 and T6 flanges for changing out the stock turbo. The turbo stays in the same stock location. Fully divided pulse manifold made from high-silicon ductile iron is designed to withstand extreme temperatures and vibration. Great for performance trucks wanting to increase airflow. Designed using modern technology, it 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.
