4-inch constant-diameter pipes with Straight-thru muffler cuts backpressure up to 81 Percent. Turbo Back System. 5-inch Chrome Tip. F-250 & F-350 PICKUPS and EXCURSIONS: Banks 4 inch Monster turbo-back stainless steel exhaust features streamlined turbine-outlet pipe, intermediate pipe and tailpipe all 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). Designed for trucks without a catalytic converter. 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. And the 5 inch polished rolled-edge tip has an adjustable clamp for positioning on tailpipe. Get it in your choice of chrome-over stainless or high temp black! (And to help keep it looking good, there's a 1/2 inch air gap to keep heat from tarnishing the finish).Important: Some vehicle configurations require an extension kit for proper fit. Pickups other than standard-cab long-bed or extended-cab short-bed require Exhaust Extension Kit. Extended Cab Long Bed #53517 required, Crew Cab Short Bed #53516 required, Crew Cab Long Bed #53518 required.
