Hurry up! Current stock:
BD Full Bore Manifold for 2001 - 2010 Chevy GMC 6.6L Duramax

Part # 1041460

The BD 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. Constructed of high silicon ductile iron that prevents cracking from heat expansion and vibrations. The BD Manifold compliments BD`s SuperMax turbo charger kit for fully engineered exhaust flow design.

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
BD's Full Bore 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


At this time this kit does not come with a manifold gasket. Currently the highest quality gasket is being made by GM. See the chart below for OEM part numbers.
