BD Full Bore 01-07 Chevy/GM Duramax Exhaust Manifold

BD “Full Bore” 01-07 Chevy/GM Duramax LB7,LLY, & LBZ Exhaust Manifold

Improve exhaust flow, reduce exhaust gas temperature (EGT) and realize greater power gains with the new “Full Bore” driver’s side exhaust manifold for the ’01-’07 GM Duramax.

You may not know it, but the factory driver’s side manifold is pinched down to allow clearance for the steering shaft, which actually isn’t required. As a result, this manifold flows 80% of the passenger side manifold.
The BD Full Bore exhaust manifold restores exhaust flow to match the passenger side, and is a direct, bolt-in replacement for the factory part (GM gasket required).
The BD Full Bore manifold is made from high-silicon ductile iron to resist cracking from high temperature and vibration, and is even tapped to accept the most popular EGT probes.
