4 inch stainless mandrel-bent system. Dramatically improves flow; slashes backpressure up to 81%; lowers EGTs, safely clears spare tire; throaty sound; huge polished ob-round tips.

F-250 & F-350 PICKUPS: (For non-cat. converter vehicles only) Monster exhaust's 4 inch 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 inch 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 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.

For non-cat. converter vehicles only

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