2003-2004 Cummins Exhaust System Kit - CCLB (48642)

Fits

The 4 inch Monster exhaust system flows up to 122 percent better than stock and virtually eliminates backpressure to give your Cummins better throttle response, throaty sound and more power you can feel from your seat! The 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. 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 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)
