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 back-pressure.
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 includes two huge 6X5" polished-stainless rolled-edge tailpipe tips, and comes with a Lifetime Warranty.
NOTE: These exhaust systems do not fit Cab/Chassis models.
