Banks Monster Diesel Duals 4" exhaust system offers up to a 150% improvement in airflow and slashes backpressure up to 98%. The streamlined intermediate pipe(s) and 3-1/2" tailpipes are formed of stainless, heavy-wall tubing with constant-diameter bends to maximize airflow and cut backpressure.

The polished-stainless Monster muffler features a straight-through 4"-diameter flow-path with an exclusive expansion chamber to dissipate the annoying mid-range exhaust drone that accompanies most straight-through mufflers. Monster muffler utilizes spun ceramic, very-high-temperature packing, more than triples stock exhaust flow, and delivers the signature Monster sound in stereo. Now for the cool part: Banks’ exclusive 6” X 5” ob-round polished-stainless angle-cut rolled-edge tailpipe tips (patent pending)! System safely clears spare tire, shocks and brake lines.
