F-250 & F-350 PICKUPS: (For non-cat. converter vehicles only) Monster exhaust's 4" pipes bolt behind the turbocharger. The streamlined turbine-outlet pipe, intermediate pipe(s) and tailpipes are formed of stainless, heavy-wall tubing with constant-diameter bends to maximize flow, lower exhaust gas temps and slash backpressure up to 81%. (Available with or without 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. Now for the cool part: Banks' exclusive 6" X 5" ob-roundpolished-stainless angle-cut rolled-edge tailpipe tips (patent pending)! System safely clears spare tire, shocks and brake lines.
