I dunno. Is it just me, or have my ears grown so knowledgable of mustang exhausts that without seeing what rumbly V8 is coming down the street, I can tell you if it's a stang or not? I noticed this the other day, it's almost as if NO other musclecar can produce the same type of sound. That's all IMO though...just wanted to see if I'm going insane or not, or if someone else has this ear for sound
