5.7L HEMI & 4.7L RAM PICKUP (2002-09 only): Banks' 3" constant-diameter Monster exhaust pipesâ€”formed of heavy-duty stainless steelâ€”bolt behind the catalytic converter to slash backpressure up to 88%, improving performance, durability and fuel efficiency. The straight-through Monster muffler delivers a throaty, yet civil, exhaust note and flows up to 65% better than stock. The system includes Banks' exclusive 6" X 5" ob-round (patented design) angle-cut rolled-edge tailpipe tip in your choice of polished chrome-over stainless or high-temp black! And to help keep it looking good, there's a 1/2" air gap to keep heat from tarnishing the finish. An adjustable clamp lets you position it on the tailpipe just right. Installation of the lightweight, direct-fit-system is bolt-on easy.
