Banks Power 03-07 Ford 6.0L Excursion Monster Exhaust System - SS Single Exhaust w/ Chrome Tip

4 inch stainless constant-diameter pipes and straight-thru muffler nearly doubles flow. Lower exhaust temps. Virtually no backpressure. Rich, throaty sound. Available for F-250, F-350, F-450 & F-550 Pickup & Excursion. Monster exhaust system flows up to 91.5% better than stock and virtually eliminates backpressure. The streamlined 4 inch intermediate pipe(s) and tailpipe are formed of stainless, heavy-wall tubing with constant-diameter bends to maximize flow and lower exhaust gas temps. Banks replaces the factory's restrictive muffler with a polished-stainless steel Monster muffler, featuring a straight-through 4 inch 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. Includes a 3-1/2 inch
