XDP Driver Side High-Flow Exhaust Manifold XD342

Posted on by


Upgrade the restrictive stock exhaust in your 2001-2010 GM 6.6L Duramax with the XDP Driver Side High-Flow Exhaust Manifold XD342. The XD342 manifold eliminates the “dented” or “kinked” exhaust manifold that came standard on the 2001-2010 GM 6.6L Duramax. As a result of removing the factory restriction you will see an increase in exhaust flow, faster turbo spool up, lower EGTs, and improved performance. In other words, the XDP High-Flow Exhaust Manifold will help let your diesel maximize its true potential.

In addition, this will also work as a direct replacement on 2011-2016 LML trucks as they already came with this freer-flowing style exhaust manifold. This is ideal if your stock manifold is cracked or worn out. Constructed of durable cast iron for maximum durability and leak-free performance. Kit includes all necessary gaskets and hardware required for installation.
