Bankspower - Diesel Performance Specialists

(5.4L engine only) Formed of heavy-duty stainless steel, Banks' increased-diameter mandrel-bent Monster exhaust pipes (3" intermediate pipe and 3.5" 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. Includes 5-1/2 x 5-3/8 weld-on ob-round polished-stainless angle-cut rolled-edge tips (patent pending). 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.
