Diamond Eye KIT 4in Catback MFLR RPLCMENT PIPE Single AL: 2004.5-2007.5 DODGE CUMMINS 600

If you're working on a 2004.5 through 2007.5 Dodge Ram 2500 or 3500 with the 5.9L Cummins engine, this 4-inch aluminized replacement pipe from Diamond Eye is designed to fit right in. This part is specifically for replacing the muffler section of your cat-back exhaust system, giving you a more direct flow path.

Diamond Eye uses CNC mandrel bending to shape this pipe, which helps maintain consistent diameter throughout the bend. This process is important for exhaust flow, especially on a diesel engine where efficient exhaust gas evacuation can make a difference. The aluminized steel construction offers a good balance of durability and cost for this application.

This kit is intended as a direct replacement for the muffler section, so it should bolt up to your existing cat-back system or other compatible components. It's designed for all cab and bed lengths for the specified truck models.
