Overview

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.

Features

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

Note

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.
