anyone heard them on a stang???? i am looking in to buying them but dont want to get them and have them be all loud like my flowmasters...... also could hear what the the dynomax ultra flows sound like(pretty much the same thing as the max flow)-------so if youve hear either of these on a stang without cats let me know how loud they are at crusing speeds---i dont really care if theyre loud at full throttle....
