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 dramatically increasing flow and cutting backpressure. Tested and refined by Banks engineers using Computational Flow Dynamics software, 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. The system safely clears the spare tire, shocks and brake lines, and includes two huge 6X5" ob-round (patented design) angle-cut rolled-edge tailpipe tips in your choice of polished chrome-over stainless or high-temp black! And to help keep them looking good, there's 1/2" air gaps to keep heat from tarnishing the finish. Adjustable clamps let you position them on the tailpipes just right. Please note: These exhaust systems do not fit Cab/Chassis models.
