2003-2004 Dodge Cummins SCLB/CCSB w/Factory Catalytic Converter


The 4-inch Monster exhaust system flows up to 122 percent better than stock and virtually eliminates backpressure giving you a more kick-in-the-pants power feeling from that Cummins under the hood! Banks streamlined 4-inch turbine outlet pipe with provision to retain stock catalytic converter, intermediate pipe(s) and tailpipe are formed of stainless, heavy-wall tubing with constant-diameter bends to maximize airflow and lower exhaust gas temps.

Banks replaces the factory's restrictive muffler with a polished-stainless Monster muffler featuring a straight-through 4-inch diameter path that flows up to 129 percent better than stock. The Banks-designed expansion chamber dissipates the annoying mid-range exhaust drone that accompanies most straight-through mufflers. The monster muffler utilizes spun ceramic, very-high-temperature packing and delivers an authoritative - but never intrusive - exhaust sound. And the 5-inch polished rolled-edge tip has an adjustable clamp for positioning on the tailpipe. Get it in your choice of chrome-over stainless or high temp black! (And to help keep it looking good, there's a 1/2 inch air gap to keep heat from tarnishing the finish)
