The original car in this post sounds pretty bad a$$. Yes there are others that sound better but there are far more that sound worse. Sometimes we forget that in full factory form these cars sounded less impressive than a Maytag.

oh i can go lower. but when you put it in gear you have to keep it idled up. whats the point for just the sound. my 90 mustang ran low 12's and i had the set around 650. it was a stick car though
