The BD-Power 1041460 Full Bore Exhaust Manifold will restore the balance to your engines exhaust flow, reduce cylinder load and reduce exhaust gas temperatures. The factory driver side exhaust manifold in your 01-10 Duramax is pinched down to allow for steering shaft clearance that isn't even required! As a result, your exhaust flow is significantly disrupted. The BD-Power Full Bore Exhaust Manifold addresses this issue by maintaining internal bore size. Made from high-silicon ductile iron, the Full Bore is a direct, bolt-in replacement for the factory manifold and is even drilled and tapped to accept the most popular EGT probes.

Stock Exhaust 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-Power Exhaust Manfilold:

  • Contaings Exhaust Temperature Probe Port
  • Maintains consistent exhaust pressure and temperature on both sides of the engine
  • Flow matches the passenger side manifold and balances the engines exhaust pressure.

 Manifold gaskets not included.

Just makes sense to put this part in, not to mention the Pyrometer hole making it easy to add the EGT probe from Edge. Had to soak the bolts in Kroil to get them to loosen up, after removing the manifold heat shield (only broke 2/4 bolts), driver side intercooler tube, tire still on. Also replaced the 11 bolts for it, including 2 studs with ARPs, even though they haven't made their way here yet. Intermediate level job, doesn't take more than a few hours if you re-use the gasket, but I opted to replace them, also not available here yet, but XDP is always the first place I check.

Takes 2 to 3 hours to install in the driveway. I'm a certified automotive technician and this was the best exhaust upgrade for the dollar. Then you remove the O.E. manifold and look at the new one you'll under stand why this is a must have! The diesel even sounds more balanced.

I like the quality and workmanship. It installed with no messing with bolt holds. I did not notice anything special with performance but I do not have anything unusal on the engine. The old manifold was really restricted conpare to BD manifold. I would get another for my next vechile.

Most Popular Questions

Is this just a manifold for the drivers side?
View Staff Answer 

The BD-Power 1041460 Full Bore Exhaust Manifold covers only the driver side manifold. The factory driver side exhaust manifold in the 01-10 Duramax is pinched down. This pinch restricts the exhaust flow significantly and disrupts the balance of the engine. With the addition of this manifold you’ll match the passenger side flow and balances the engines exhaust pressure. * At this time this kit does not come with a manifold gasket. Currently the highest quality gasket is the GM gasket.
