Cool Sound.
Cool Tips.
4" stainless mandrel-bent system. Dramatically improves flow; virtually no backpressure; lowers EGTs; safely clears spare tire; throaty sound; huge polished ob-round tips.
Monster® Diesel Duals Exhaust
Monster Diesel Duals 4" exhaust system flows up to 88% better than stock and virtually eliminates backpressure. The streamlined 4" turbine outlet pipe (not required with 325 hp systems), intermediate pipe(s) and 3-1/2" tailpipes are formed of stainless, heavy-wall tubing with constant-diameter bends to maximize airflow and lower exhaust gas temps. The dual tailpipes have 52% more flow area than a single 4" tailpipe.
Banks' 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. The muffler utilizes spun ceramic, very-high-temperature packing, flows up to 129% better than stock, 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.
