My, oh my,does it ever !!! My buddy with a charger r/t was hounded by the cops and he had actual mufflers on his car. You wonder how all these harley davidsons can drive around with out any sound reducing systems..and they don't even sound good...
Could you get away with just a tube muffler like a thrush ?

As long as they tone down at speed, they would be great.
