So if its simple science...then why do new cars not do it? Heat is constanty expanding causin piping to expand, but yet I don't hear this crackle on new or newer cars. I've owned over 60 cars..and it only did this on two of them. My sc400 and my infinity q45.

It could just be the type of metal man. Thats what it is, our exhaust could get hotter than other cars but the crackling is only the metal cooling.
