I had some crackle on the passenger side and it was an exhaust leak at the connection of the muffler pipe with the over-axle pipe. You might want to check for leaks.

Yeah, my left one is bigger too...Kiddin'.

Something's loose or you have separation inside the left muffler (hopefully not).
It happened to me before in an old T/A, talk about a rattle... Check all your clamps etc...
Good luck.
