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

If you're looking to get more out of your 2004.5-2007.5 Dodge 5.9L Cummins, upgrading the exhaust system is a solid step. This 4-inch cat-back kit from Diamond Eye Performance is designed to replace your factory exhaust from the catalytic converter back, offering a less restrictive path for exhaust gases. This can lead to a slightly improved throttle response and a deeper exhaust tone.

Diamond Eye uses CNC mandrel bending to create smooth bends in the tubing, which helps maintain consistent diameter and reduces turbulence. This particular kit is constructed from aluminized steel, a well-built material that offers good corrosion resistance for everyday use. The 4-inch diameter is a popular choice for Cummins owners looking for a balance between performance and manageable sound levels. The kit is designed to fit all cab and bed lengths for the specified Ram 2500 and 3500 models.

This cat-back system is a direct replacement for your stock exhaust, meaning it bolts up without requiring welding or significant modifications. You'll want to refer to the manufacturer's installation instructions for specific details on mounting hardware and procedures.
