Banks Power "600" Single Monster Exhaust System (2004.5-2007 5.9L Cummins "600")
The 4" Cat-Back Monster exhaust system flows up to 122% better than stock and virtually eliminates back-pressure. Banks streamlined 4" 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"-diameter path that flows up to 129% 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 authoritativebut never intrusiveexhaust sound. A huge 5" polished-stainless steel tailpipe tip sports a rolled edge. Double-walled design with 1/2" air gap keeps heat from tarnishing the exterior mirror finish. Adjustable clamp for positioning on tailpipe.
