4-inch 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. Tested and refined by Banks engineers using Computational Fluid Dynamics software, then validated through extensive temperature testing in all areas: before and after the DPF, 6-inch out from the tip, by the spare tire, shocks, wiring, hoses, and more. The system includes Banks patented 6-inch X 5-inch ob-round (patented design) angle-cut rolled-edge tailpipe tip in your choice of polished chrome-over stainless or high-temp black! An adjustable clamp lets you position it on the tailpipe just right. Please note: These exhaust systems do not fit Cab/Chassis models.
