I know that my MBRP turbo back exhaust has a noticeable drone at highway speeds. I know that MBRP has a resonator that goes on the front pipe that is supposed to eliminate the drone. I feel that mine was quieter with straight pipe at highway speeds (under 2200 rpms). I know that a buddy that has a silverline and his is louder than mine outside the cab, but I haven't talked to him about the drone in the cab.
