Ford Excursion: Banks 4" Monster exhaust pipes bolt behind the turbocharger. The streamlined turbine-outlet pipe, intermediate pipe and tailpipe are formed of stainless, heavy-wall tubing with constant-diameter bends to maximize flow, lower exhaust gas temps and slash backpressure up to 81%. Kit includes a cast, large-bore Power Elbow™ housing.
The polished-stainless Monster muffler features a straight-through 4"-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. A huge 5" polished-stainless steel tailpipe tip sports a rolled edge. Double-walled design with 1/2" air gap keeps heat from tarnishing exterior mirror finish. Adjustable clamp for positioning on tailpipe.
