Get rid of the Roush mufflers, I did. Go back to stock mufflers. Add electronic adjustable cut outs to the system......Just be sure they are adjustable ones so you can control the cut out flow....Best of all worlds. Quiet in the neighborhood, full open loud at the track, mellow when cruising, but you control it. best regards Plum
