1999-2003 Powerstroke Exhaust System Kit (48656-B)

Fits

The Banks 4-inch Monster turbo-back stainless steel exhaust features streamlined turbine-outlet pipe, intermediate pipe and tailpipe all formed of stainless, heavy-wall tubing with constant-diameter bends to maximize flow, lower exhaust gas temps and slash backpressure up to 81 percent. (Available with or without a cast, large-bore Power Elbow housing). Designed to retain stock catalytic converter. The polished-stainless Monster muffler features a straight-through 4-inch diameter flow-path with a Banks-designed expansion chamber to dissipate the annoying mid-range exhaust drone that affects most straight-through designs. The muffler utilizes spun ceramic, very-high-temperature packing, more than doubles stock exhaust flow, and delivers an authoritative - but never intrusive - exhaust sound. And the 5-inch polished rolled-edge tip has an adjustable clamp for positioning on the tailpipe.
