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 



The stangs still have the purest sounding, cleanest, meanest, and strongest exhaust out there. Albeit from the 60's to the present.
Just when you though it was you alone! I think all of our girlfriends and wives think we are all crazy at first. You know they notice us listening before we even say a thing.
