03-04 Dodge Cummins aFe Aluminized Turbo Back Exhaust System. The system features 4" Band Clamps, 8" Round x 30" Length aFe Muffler, 4" Down Pipe, Bayonet Hangers, and will fit all wheelbases.
There is no difference in the flow characteristics of the various materials. A 4" Aluminized flows the same as a 4" Stainless. The difference is cost of the material. Aluminized steel is significantly cheaper than stainless
The exhaust is pretty similar to stock on the idle and cruising speeds. Where you see the increase in sound is under accelleration. The increased flow will also help spool the turbo faster so you will hear the turbo a bit more as well.
Stock turbo and the muffler is a straight through perforated core so there is no quiet or loud position. A few years back aFe used a louvered core muffler that had the quiet and loud position but we don't use that muffler design anymore.

Sounds great
Does this truck have stock turbo and stock exhaust manifold?
Is this with the muffler in the quiet or loud position?
