BD Diesel Full Bore Driver Side Exhaust Manifold for 2001-2010 Chevrolet/GMC Silverado/Sierra 2500/3500 (6.6L Duramax) - 1041460

Fits select 2001-2010 Chevrolet Silverado and GMC Sierra 2500 HD/3500 models with the 6.6L Duramax diesel engine.

The BD Diesel Full Bore Exhaust Manifold is engineered to eliminate the significant exhaust flow restriction found in the factory driver-side manifold. The original equipment unit is heavily "pinched down" to provide steering shaft clearance, which creates an imbalance in exhaust backpressure between the cylinder banks. This BD Diesel replacement restores flow, helping the engine run smoother and more efficiently.

Constructed from high-silicon ductile iron, this manifold is designed to withstand the high thermal loads of a heavy-duty diesel engine without cracking or warping. It is a direct bolt-in replacement for the factory component, utilizing OEM mounting points for a straightforward installation. For those monitoring performance, the manifold comes pre-drilled and tapped to accept the most common EGT (Exhaust Gas Temperature) probes.
