Whenever the car is running everything is fine. However, when I turn it off, a minute or so later white smoke starts pouring out of my secondary cat. I've cleaned them off with degreaser and acetone so its nothing on the surface that's burning. It's also only occuring on the passenger side.

No smoke comes out of the tail pipe either.
