4 inch 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 4 inch exhaust system flows up to 88% better than stock and virtually eliminates backpressure. The streamlined 4 inch turbine outlet pipe (not required with 325 hp systems), intermediate pipe(s) and 3-1/2 inch 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 inch tailpipe.

Banks' polished-stainless Monster muffler features a straight-through 4 inch 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 inch X 5 inch ob-round stainless angle-cut rolled-edge tailpipe tips--in your choice of polished chrome-over stainless or high-temp black! And to help keep them looking good, there's 1/2 inch air gaps to keep heat from tarnishing the finish. Adjustable clamps let you position them on the tailpipes just right. System safely clears spare tire, shocks and brake lines.

Split-dual exhaust applies to single-rear wheel applications only (they do not fit appropriately on duallys)
