Fitment Notes

Passenger side (right side) exhaust manifold only - for driver side, see BD Diesel 1041460. For a complete driver and passenger side kit, see BD Diesel 1041462.
Direct replacement for OEM passenger side manifold GM part number 12624683.
Gaskets and required installation hardware are included in this kit - no need to source additional components.
EPA-compliant - legal for sale and use in all 50 states under federal EPA guidelines (EMS:2).

Features

65% thicker casting construction than the OEM manifold - significantly reduces the risk of warping and cracking under high heat cycling and demanding tow/haul conditions.
Manufactured from high-silicon ductile iron for superior resistance to thermal stress and vibration-induced fatigue.
5% increase in overall exhaust flow compared to the factory manifold - supports improved exhaust velocity, lower EGTs, and more consistent turbo spool.
High-temperature corrosion-resistant protective coating extends service life and maintains appearance under prolonged heat exposure.
Direct bolt-on fitment - designed as a drop-in replacement requiring no modifications.
Complete kit includes all required gaskets and fasteners for a straightforward installation.

Product Description

The BD Diesel 1041461 is a passenger side (right side) exhaust manifold kit engineered as a heavy-duty replacement for the factory manifold on 2001-2016 GM Silverado and Sierra 2500HD/3500HD trucks equipped with the 6.6L Duramax engine. Constructed from high-silicon ductile iron with castings that are 65% thicker than OEM, this manifold is built to withstand the repeated thermal expansion and contraction cycles that cause factory manifolds to warp, crack, and leak - especially on trucks used for heavy towing, hauling, or performance applications.

Beyond improved durability, the BD manifold delivers a 5% increase in exhaust flow over the factory design, helping to optimize exhaust velocity, reduce exhaust gas temperatures, and support consistent turbocharger spool. A high-temperature corrosion-resistant coating protects the manifold's exterior for long-term reliability. Everything needed for installation - gaskets and fasteners - is included in the kit, making this a true drop-in replacement for OEM GM part number 12624683. EPA-compliant and legal for use in all 50 states.
