Diamond Eye 4 INCH Muffler Replacement PIPE..SS..2004-2006 DODGE OEMR400-SS

If you're looking to get more exhaust flow out of your 2004.5-early 2007 Dodge 5.9L Cummins, this muffler delete pipe from Diamond Eye Performance is a solid option. It's designed to replace the factory muffler, opening up the exhaust path for better performance. This pipe is made from stainless steel, so you don't have to worry about rust down the road.

Diamond Eye uses CNC mandrel bending to ensure a smooth, consistent bend radius, which helps maintain exhaust flow. The 4-inch diameter is a direct match for the factory exhaust system on these trucks, making installation pretty straightforward. You'll likely notice a deeper exhaust tone and potentially a slight improvement in throttle response after installing this.
