4" stainless mandrel-bent system. Dramatically improves flow; virtually no backpressure; lowers EGTs, safely clears spare tire; throaty sound; huge polished ob-round tips.
F-250/350 PICKUP: Banks Monster Diesel Duals 4" exhaust system flows up to 76% better than stock and virtually eliminates backpressure. The streamlined intermediate pipe(s) and 3-1/2" tailpipes are formed of stainless, heavy-wall tubing with constant-diameter bends to maximize flow and lower exhaust gas temps. The dual tailpipes have 52% more flow area than a single 4" tailpipe. The turbine outlet pipe* has a Banks-designed resonator that eliminates the screechy turbo racket (for '03 Power Stroke only).
Banks' polished-stainless Monster muffler features a straight-through 4"-diameter flow-path with an exclusive expansion chamber that dissipates the irritating mid-range exhaust drone that plagues most straight-through designs. The muffler utilizes spun ceramic, very-high-temperature packing, more than doubles 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.
*Banks turbine outlet pipe not required for '06 Power Stroke with manual transmission

“Considering the fact that the fuel economy savings are substantial and the fact that the stainless steel exhaust will last the life of the vehicle, the Banks system is well worth the investment.”
