2004-2008 Ford F-150 4.6L/5.4L Banks Cat-Back Exhaust System – Crew Cab – 5.5ft. Bed (Black Tip) 48743-B

3 inch stainless constant-diameter direct-fit cat-back system cuts backpressure up to 79% & flows up to 138% better. Throaty sound; huge polished tip. Formed of heavy-duty stainless steel, Banks’ increased-diameter mandrel-bent Monster exhaust pipes (3 inch intermediate pipe and 3.5 inch tailpipe) bolt behind the catalytic converter, cutting backpressure up to 79% and increasing flow up to 138% for increased power, longevity and fuel efficiency. The polished-stainless straight-through muffler outflows stock, and delivers a commanding, yet civil, exhaust note. The system includes Banks’ exclusive ob-round (patented design) angle-cut rolled-edge tailpipe tip in your choice of polished chrome-over stainless or high-temp black! And to keep it looking good, there’s a 1/2 inch air gap to help keep heat from tarnishing the finish. An adjustable clamp lets you position it on the tailpipe just right. The lightweight, direct-fit-system bolts on easily. Fully compatible with Ford’s factory warranty, the entire system is covered by Banks’ 5-Year Limited Warranty.
