Banks Power 03-04 Dodge 5.9L CCLB Monster Exhaust Sys - SS Single Exhaust w/ Black Tip

This turbo-back exhaust system features 4-inch constant-diameter pipes and a straight-through Monster muffler, which Banks Power claims cuts back pressure by up to 81% and flows up to 122% better than stock. The system includes a streamlined 4-inch turbine outlet pipe (with provision for retaining a stock catalytic converter, though this specific part number is "no cat" compatible), intermediate pipe(s), and a tailpipe made of stainless, heavy-wall tubing with constant-diameter bends. The muffler is made of polished stainless steel, has a 4-inch diameter path, and incorporates an expansion chamber to dissipate mid-range exhaust drone. It uses spun ceramic, very-high-temperature packing for an authoritative but not intrusive sound. The system is finished with a 5-inch Cerakote black rolled-edge tip with a 1/2 inch air gap to prevent heat tarnishing.
