01-05 Gm 6.6L Duramax Rfi Cold Air Intake Enclosed System

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.

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" out from the tip, by the spare tire, shocks, wiring, hoses, and more. First we tested our own exhaust then we tested all of the "competitors." They all tested hundreds of degrees hotter than Banks and stock!

The system includes a huge 6X5" polished-stainless rolled-edge tailpipe tip, and comes with a Lifetime Warranty.
