About the BD Duramax Exhaust Manifold

Duramax Balancing Big Bore Exhaust Manifold. Makes it easy for your engine to exhale. Driver`s side full bore exhaust manifold for the Duramax balances your engine power, reduces cylinder load, reduces exhaust temperature, exhaust backpressure and improves fuel economy. BD uses a high silicon Ductile iron that prevents cracking from heat expansion and vibrations. Manifold gaskets required.

The stock manifold:

  • Only flows 80% of the passenger side manifold
  • 3 cylinders only operate at 80% capacity & load others down
  • No access to measure exhaust temperature

The BD manifold:

  • Flow matches the passenger side manifold and balances the engines exhaust pressure.
  • Maintains consistent exhaust pressure and temperature on both sides of the engine. Contains Exhaust temperature probe port.
