2003-2004 Dodge Cummins came factory equipped with a 3.5" exhaust from the turbo to front of muffler, and then a 4" from rear of muffler to tailpipe. While this system is reasonably adequate for stock to mildly powered trucks, a larger diameter system or higher flow system from Diamond Eye, FLO~PRO, Magnaflow, MBRP, or Silverline is mandatory on any Cummins equipped with even mild upgrades, or for those towing heavy loads. And of course, there are other benefits to adding an exhaust kit besides purely functional, aftermarket kits not only sound good, but they look even better, especially with a nice polished or black tip to finish it off. For those looking for something even more unique, try out a set of exhaust stacks by MBRP. Imagine a set of 6" Bullhauler turnout stacks sticking out the bed of your truck. And you wouldn't believe the shuddering sound they produce, either!
