Upgrading your diesel truck’s stock exhaust with an aftermarket exhaust is one of the easiest ways to enhance its overall performance. Replacing your stock headers/manifolds with an aftermarket pair will assist in allowing your Duramax engine to breathe more efficiently leading to a drop in exhaust gas temperatures and a boost in horsepower and torque.
