Details

Application:
2001-2015 GM 6.6L Duramax
The Dorman 674-731 Left Side Exhaust Manifold is a direct replacement for your 2001-2015 GM 6.6L Duramax. This manifold features a "full bore" design that isn't kinked like the factory manifold on the 2001-2010 models. This makes it a popular upgrade for the earlier trucks as the increased flow will "balance" out the engine helping with throttle response and better overall performance. 

FEATURES: 

  • Direct Fit 
  • Upgrade On 2001-2010 Duramax Trucks 
  • Replaces GM OE Part#: 12624684, 12637647, 97224587
2011-2015 LML Note: Because this is the factory manifold that comes on the 2011-2015 LML Duramax it is simply a replacement part for the LML and not an upgrade like the 2001-2010 trucks with the "kinked" exhaust manifold.
