[QUOTE=Jeff Kleiner;270076]What engine? Coyotes are quiet anyway if that's what you are going to be running. Engine type and specs are generally the determining factor as far as noise level. All things being equal I think the sound level is pretty similar between the J and 4X4 since they're going through the same muffler either way.
