Ok so I just noticed today that when the car is warmed up or has been pushed for a bit, when I stop and get out the car with the engine still on, I can hear little crackles from the exhaust. Like...a log fire. Not really loud, but I can hear it quite easily standing behind the car. I assume it's normal, but being a paranoid android that I am, I thought I'd ask. :)

Are you talking about the popping sound? If so, then that's normal. I get that too. Do you have an aftermarket exhaust?

Normal sound. It's the expansion/contraction of the metal in the exhaust system.
