Wake up your rare Powerstroke Excursion with this 4-inch stainless constant-diameter pipes and straight-thru muffler that flows up to 91.5 percent better than stock and virtually eliminates backpressure and gives that distinctive Powerstroke growl! Banks also 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. A huge 5-inch stainless steel tailpipe tip in your choice of polished chrome-over stainless or high-temp Black sports a rolled edge. And to help keep it looking good, there's a 1/2 inch air gap to keep heat from tarnishing the finish. An adjustable clamp lets you position it on the tailpipe just right.
