does anybody have any actual expirence on which one is quieter? i've always herd about how quiet the exmag is and then i drove a car with the exmag on it and it was a lot louder than i expected. i've never really her a lot about the WS, others usally reccoment the exmag over it. i'm just looking for a really quiet (as close to stock as possible) exhaust. what do you think?
