well i saw a stang with stingers on it in a parkin lot so i left the guy a note and told him to call me so i could hear them haha, anyway he called me a took me for a ride, and they werent as loud as i expected. the way some people talk about them, is like they are unbearable but it wasent to loud inside the cab, also they werent as loud as i expected at idle as well, so i finally figured it out, i am gonna go with the Stingers
