Monster® Exhaust


(2011-15 trucks) 4" heavy-duty stainless DPF-back Monster Exhaust system with constant-diameter intermediate pipe and tailpipe. Exclusive CoolCuff® design lowers tailpipe temperatures as much or more than stock while simultaneously improving flow and cutting backpressure by nearly 57%.

The CoolCuff design is tested and refined by Banks engineers using Computational Fluid Dynamicssoftware, then validated through extensive temperature testing in all areas: before and after the DPF, 6" out from the tip, by the spare tire, shocks, wiring, hoses, and more. First we tested our own exhaust then we tested the others. Result: Monster Exhaust measured well over a hundred degrees cooler than the competition, and cooler than stock, too!

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 ½" air gap to keep heat from tarnishing the finish. An adjustable clamp lets you position it on the tailpipe just right.
