Gale Banks Engineering Monster® Exhaust System for 2004 Ford F250/350 6.0L Power Stroke Supercab Short Bed

Catalog #: 77605.179
Gale Banks Engineering Part #: 48784

Monster exhaust system flows up to 91.5% better than stock and virtually eliminates backpressure. Formed of heavy-duty stainless steel, Banks 4" constant-diameter Monster exhaust pipes bolt behind the catalytic converter. The straight-through muffler with Banks’ exclusive expansion chamber delivers a throaty, yet civil, exhaust note, and the handsome 5" polished-steel dual-wall tailpipe tip with a rolled edge stays mirror bright.


Banks Monster exhaust outflows stock and the competition. The streamlined 4" intermediate pipe(s) and tailpipe are formed of stainless, heavy-wall tubing with constant-diameter bends to dramatically reduce backpressure. Banks replaces the factory's restrictive muffler with a polished-stainless steel Monster muffler, featuring a straight-through 4"-diameter flow-path with a Banks-designed expansion chamber which dissipates the annoying mid-range exhaust drone that’s so prominent in competitors’ straight-through mufflers. The muffler utilizes spun ceramic, very-high-temperature packing, more than doubles the stock flow and delivers an authoritative—but never intrusive—exhaust sound. The 3-1/2" turbine outlet pipe* with Banks’ resonator eliminates screechy turbo noise (resonator for ’03 Power Stroke only). 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.
