Banks Monster Diesel Duals exhaust systems slash backpressure, lower EGTs, and produce a roar that will make your fellow ghouls green-eyed. Banks created the Monster exhaust systems from 100 percent stainless steel with a constant diameter to improve exhaust flow and give you a scary surge of power. These systems come complete with polished or black high-temp tips and a polished straight-through muffler (most applications), plus all required hardware for an easy installation. They will safely clear the factory spare tire location. Note: Systems are not designed to be used with 5th wheel hitches.
