Dorman's driver-side Exhaust Manifold Kit was precision engineered and a popular upgrade for your 2001-2016 GMC/Chevy 6.6L Duramax LB7/LLY/LBZ/LMM/LML 2500HD/3500HD/4500HD truck. This kit features a "full bore" design that isn't twisted like the factory manifold on the 2001-2010 models. It has increased the flow, which will set a balance on the engine and help with throttle response for better overall performance on your truck. Dorman's exhaust manifold set is the perfect replacement for reliability and ease of mind.


  • Direct replacement
  • Upgrade on 2001-2010 Duramax trucks
  • Replaces GM OE Part#: 12624684, 12637647, 97224587


  • Because this is the factory manifold that comes on the 2011-2015 LML it is simply a replacement part and not an upgrade like the 2001-2010 trucks.
